Thermal Long Sleeve Undershirt (Black)

I ordered from Mystery United for the first time and was not disappointed. The delivery was fast, the packaging was high quality, and the shirts are very stylish. In my case, the Europe Mystery Box included event shirts from Athletic Bilbao and Young Boys Bern. Excellent! There was also a description of the respective clubs. I would happily order again anytime. At the moment, a few friends and I are also planning to try the Mystery Tickets. We’re excited to see what it’s like.

Last Sunday, 08/03/2026, I went to MSV Duisburg with my father. Everything was well organized from start to finish, with the tickets and tips on where to park, etc.
We were seated close to the MSV supporters, which created a great atmosphere and made it a really nice match.

Fast shipping and top quality. I asked for the Mystery Box as a birthday gift. The surprise effect was definitely there, it included a cool shirt from a traditional club. There was also a sheet with information about the team. I would definitely ask for it again and hope you’ll be around for a long time.

Nice scarf with excellent informations. I will obviously order another one.

Beautiful shirts, even from lesser-known clubs and that’s exactly what makes it so fun.

Everything was great, fast delivery. The gift was a complete success!

Fast delivery and a great shirt.

All good and the size fits perfectly, just as I ordered it.

We had a great mystery football trip to MSV Duisburg. The tickets were perfectly arranged and the communication was very good. All in all, a very positive experience!

Well organized. Great experience!!

The order arrived very quickly and I’m very satisfied with the quality! Simply a perfect company!

Gave the tickets as a gift, it turned out to be a real experience. We got to visit a club with an amazing atmosphere, a large fan base, and great seats.
All that for “just” 40 euros.
Definitely recommended!

Great match and great atmosphere. However, we were in the completely wrong section and couldn’t see anything. The stand was overcrowded, you were basically standing between the toilets trying to watch, if you know what I mean. (I saw on TikTok that you were at the game yourselves.) MSV Duisburg.

I’ve ordered several times already and always received exciting, mostly high-quality shirts. My preferences were taken into account every time. Definitely worth the money!

I bought a mystery shirt and it arrived the very next day. The shirt is fantastic, super high quality! I also received a sheet with information about the club; without that, I wouldn’t have known which club it was.

I recently started ordering two boxes every month: the Classic Box and the England Box! And an accessory ☺️ Everything is always neatly packed! Even when ordering two boxes, they arrive in separate packages, not all crammed into one! It’s always a great experience. Today I received my third Twente shirt and the away shirt from Watford! They always take your preferences into account! I always include a note with the shirts I’ve already received, to keep the team informed. I don’t want duplicates hanging in my closet! So far, no duplicate shirts 🫡 Very satisfied with Mystery United! 🫶🏻

Fast processing,
the surprise with the shirt was a success!

Great quality!

Ordered multiple times and always delivered quickly. Clearly specified which shirts not to receive, and that has always been respected. One very happy son here every time!

As usual a great shirt ..this time Argentinian club !! Great present for a 10 year old boy ! 

Fast service, great price, and I received a mystery shirt just the way you’d want one. A special 3. Bundesliga shirt. I’ve been a huge football fan for over 30 years, but even I didn’t know this team: SV Waldhof Mannheim.

Highly recommended.
I got the CL Box and the Euro Box.
Inside were shirts from AC Milan and FC Utrecht.
Great packaging and fast delivery.
I’m already placing another order!

Beautiful shirt, highly recommended for its quality and delivery time.

On 14/01/2026 I placed an order with Mystery United and received two awesome shirts: the 2025–2026 home shirt of POGON SZCZECIN 😍 and the super nice 2024–2025 away shirt of KAIZER CHIEFS FC!
It was the first time I ordered something for myself, and I'm very satisfied! Clubs you normally wouldn’t get a shirt from 😁
Best regards,
Jonas Vansimpsen

My son was thrilled with all three shirts he’s received so far! Thank you!

My son thought it was a great birthday surprise.

Good quality shirt!

Every shirt we ordered was a great surprise for my football-loving boys. And even when the size didn’t fit, support responded quickly and sent a replacement. Very professional team, thank you!

A great shirt with fun facts about the club and a very fair price, quickly delivered and well protected.

I’ll definitely be ordering more!

Ordered here several times and always well delivered. Great quality and fun shirts and scarves! Top!

Excellent customer service that thinks along with you and finds a fitting solution, and they’re easy to reach if a delivery gets lost.

It’s a beautiful shirt and one that no one else has.

Nice!!!!!!

At first, I ordered a size too small, but thanks to the excellent service I was able to easily exchange it for a larger size.

Fast delivery. The shirt ran smaller than the stated size.

Ordered two boxes. I shared my preferences and they were definitely taken into account. Got two awesome shirts from Leicester and Bournemouth. The kids were over the moon. Not your average kits either, real standouts. Perfect birthday gift. Would absolutely do it again!

Cool packaging, great service, and seriously awesome shirts! We got kits from Bhutan, Mexico, and even one from Africa. We’re building a really unique collection. What I love most is the club info card that comes with each shirt. I gifted my husband the quarterly Adventure Season Box, and unboxing each one is a little celebration!

Ordered some shirts. The first one was from Germany’s third division. Despite the lower league, the quality was excellent, and the design looked amazing. The second shirt was from a club in Tanzania. The quality was a bit lower than the first, but that’s often the case with shirts outside of Europe. The beautiful design, created by a fashion designer, definitely made up for it.

In short, the designs were way better than I expected, delivery was superfast, and customer service was quick and helpful. Price to quality? Best player on the market!

Great experience, I ordered more than 50 boxes for a big event and we got a huge variety (not a single jersey we got twice - all different) of jerseys from all around the globe, from Liverpool and Porto to Tanzania and India. Fast shipment and excellent customer service!

Super! 👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻

Great company!

I’ve already ordered around 10 shirts from this company. Fast delivery, always fun and unique shirts, plus a cool fact about the club included.

I had to return one once due to the wrong size. The process was quick and smooth using the online returns portal. As soon as my return arrived, I immediately received a replacement shirt.

The last two shirts I received even came with a handwritten note. Such a nice personal touch!

This is the best place to order your shirts!

Placed an order on Tuesday and received it the very next day. Clear and easy-to-navigate website. The items were neatly packaged.

User-friendly website with a great range of options. Fast shipping, high product quality and everyone was happy with the shirts received.

Mystery United always delivers the best-looking shirts. The price is totally worth it and shipping is super fast (I got my shirt 2 days before the expected delivery date!)

Nice shirt and not too expensive

It’s really fun to order a shirt without knowing which one you’ll get. The shirt I received is gorgeous. A great gift that was very well received!

Just placed an order but accidentally forgot to add one shirt. I contacted customer service and got help within 5 seconds. The missing shirt was added to the order and it was shipped out immediately.

With my order I received a shirt that didn’t quite meet my expectations.
After contacting customer service, I returned it and ordered a new one, including a note as advised earlier.
The new shirt is spot on.
Really happy with it!

We were really surprised in a good way by our order. Got a beautiful shirt. Great communication and super fast delivery.
We will definitely order here again!

Top service! I wanted to buy a mystery shirt from England for my son, but his size was no longer available on the website. After emailing customer service, they still managed to send us an English shirt in the right size. Really appreciated!

Good quality shirt, good price and lightning-fast delivery

I really appreciated the speed of delivery. I really like the shirt I received, and I think it's great that you also have “unusual” shirts from Asia, Latin America and South America! This is the second time I've ordered from you and I'm just as happy as the first time. I'll definitely be ordering again!

I placed two orders. The first one was perfect. The second time, I ordered a size smaller and it was too small. I indicated that I wanted to exchange it for a larger size, but I received the same size again. I sent a message and received a quick response and the issue was resolved. Two days later, I had the correct size and a nice shirt in my mailbox.

I give you five stars because you communicated quickly and resolved the issue quickly. We all make mistakes sometimes.

I will definitely order from you again! 👍👍

Very satisfied, would definitely come back! Perfect surprise gift.

A fun way to get a nice shirt you would never buy yourself. I got a really great shirt!

I ordered 2 boxes with a 5XL shirt. One of them (FC Eindhoven) unfortunately doesn’t fit at all, while the other one (Waldhof Mannheim) fits really well. Too bad that one turned out way too small.

Super fast delivery, everything perfect. Beautiful exotic shirts, just as I wanted. I’m 100 percent satisfied, great company.

I think it’s a great concept, I wish this had existed when I was a kid.
I’m really satisfied with how this works with you as a company.

Great and fun experience. Fast shipping, super original shirt that introduced me to a Mexican team I honestly had never heard of before!

I’ve ordered a few shirts from Mystery United, and while the concept is fun, the experience has been mixed. My first shirt was too small despite ordering a larger size, and the quality wasn’t great — it was from a third-division Portuguese club. The return process was easy though, and I quickly received a replacement from Maastricht, which was fine.

So far, I haven’t received any shirts from first-division teams, which is a bit disappointing. Overall, the service is smooth, but the shirt selection could be better.

I’ve ordered about 25 mystery shirts and every time i get a box i feel like a little kid. The tought of not knowing what kind of shirt you’re gonna get is what makes it very fun for me.

The shirts arrived on time. The client service was spot on. We had a lot of fun unveiling our mystery shirts!

All five shirts we ordered were fantastic, diverse, and our wishes and preferences were taken into account.

As a nice bonus, each came with a “Team Card” containing information about the shirt and the club.

Delivery was also very fast.

Highly recommended!

I always order with great excitement and I’m always so curious to see which amazing shirt is waiting inside the box this time.

Quick response to my request to order two identical boxes with the same shirts inside.

Everything went perfectly and the match was really fun! A fantastic day out with friends. Communication and organization were excellent.

Perfect shirt, arrived in Italy within ten days. Great website.

I received an amazing shirt from a website that’s perfectly organized down to the last detail. This definitely wasn’t my first order – and it certainly won’t be my last. Fantastic!

The packaging was really good! The Shirt was in perfekt condition!
I am so happy that I am the monthly winner of Oktober!

I always come back to Mystery United for awesome shirts, top quality and always a surprise! Fast shipping, excellent service both by email and on Instagram. They really think along with you! Great company 👍

It’s really fun to be surprised. The product quality is good. The shirt size (officially “L”) runs small, so now my daughter wears it. I’ll definitely do it again!

Communication is excellent!! Every time I’ve received a great scarf or shirt!!

Meets all expectations and wishes, you guys are awesome!

You have to be open to surprises, and then you'll be rewarded. Fast shipping, true to size, everything perfect.

The jerseys arrived quickly and in top condition.

And again 3 awesome new shirts 🤩🤩 So happy with them! This time all three from Brazil, I have no idea how they get all these shirts, but I’m seriously addicted! Thanks again for the super fast and top-notch service! 🥳👍💪 Until next time!

I got exactly the right shirt for my 12-year-old son! He’s absolutely thrilled with it. The third kit of Manchester United. We also got the shorts, so now it’s a complete set. 💪🏼

Nice shirt received, quickly shipped

Very quick personal support!

I lost a shirt of mine and contacted the customer support. I want the exact same jersey again, they reached out within not even an hour and made sure i was able to buy the same jersey.

It was delivered quickly, the website is easy to navigate, and I received an amazingly beautiful shirt.

A beautiful shirt
Easy to order via the website. You can specify if you don’t want a certain color or... a certain country, or whether you want (or don’t want) a European one. And then… surprise! Super happy with an Arsenal shirt!

Received a super nice shirt, fast delivery!

A great experience because they were really customer-friendly.

My nephew was totally surprised with a mystery box. He was very happy with it. Good quality.

We’ve already ordered mystery shirts and scarves many times for our three boys. As soon as they see the black box, they instantly light up. It’s great that they keep track of which shirts you’ve already received, and that you can indicate which clubs or colors you don’t want. For boys who are all about football, this is the perfect gift every time.

My son wasn’t too happy with the first shirt he received. After contacting Mystery United, we returned the shirt and gave them a bit more direction based on his preferences. He’s really happy with the second shirt they sent. Fast and excellent service!

Very reliable and fast shipping! Excellent communication!

Fast delivery in a beautiful box, with information about the received shirt. My 11-year-old son thought it was an amazing gift!

Fortunately, it’s a nice shirt from a top European league – in my case Young Boys Bern – even though it’s already the fourth Young Boys Bern shirt. Shipping was relatively fast, although the initially expected delivery date was postponed. The entire process and payment procedures were excellent.

Good, fast delivery, and also a quick response to the follow-up email I sent, with clear attention paid to my comments. Ordered two shirts: one was perfect, and the other from a cool club and also a nice shirt, but the collar was too large, so it ended up being too big overall. We're going to return it and have already submitted a return request.

It still needs to be reviewed, but I assume it won't be a problem.

I’ll definitely be ordering another shirt soon for my other son.

I accidentally selected the wrong mystery box. I wrote to customer support and they replied immediately, replacing the mystery box at no extra cost.
Super satisfied with the customer service!

My package got lost somewhere with PostNL, and they promptly sent me a new one.

I bought the Latin America box and received a very nice jersey from an Argentinian second division team. It also fits perfectly. I’ll definitely order again sometime next year.

I love to Open These Packs. Always getting it from my Aunt to Christmas and Birthday! Keep it going!

Good quality

Ordering a mystery box is exciting, but the whole process runs very smoothly. And then opening the package and pulling out a super cool shirt, so great to see my 13-year-old son so happy with this “gamble,” as he calls it 😁

I ordered three “England Mystery Boxes” on 28/11/2025 as Christmas gifts.
The package arrived just in time in Italy on 23/12/2025. So the delivery time was a bit long.
Aside from that, I received shirts from Ipswich Town Football Club, Queens Park Rangers Football Club, and Cambridge United Football Club (all original UMBRO/ERREA).
I’m satisfied.
If you’re planning to give one as a gift, I recommend ordering well in advance.

What a great idea and such a cool execution. The Mystery Box for adults and football fans. And the shirts don’t end up in the bin, they actually get worn.

Received a really cool shirt from Køge in Denmark. Never heard of them before, so it’s nice and original and just a great-looking shirt too!
Top service! Delivered within 24 hours of ordering.

Very beautiful

Fast shipping
My son was super happy with his mystery shirt. Well packaged.
Clear website with multiple options.

Product matches the description and expectations.

I think that the shirt that i got is very nice but i asked to get a club that is is wel known zo thats the only downside

Fast service. Every order is a new surprise. Great value for money.

The shirt I received was too small, but it was exchanged without any issues. I filled out the return form, got a reply within 2 days, and received a replacement shirt within a week. Great communication with customer service and a quick resolution. Top service!

We ordered 6 mystery boxes, all the shirts were fantastic, delivery was fast, and the quality was great. We’ll definitely order again!

Fun box with a cool shirt

I was really happy with it, beautiful colors. It will look great on my wall.

I forgot to use the discount code, but after reaching out, I received a message within 10 minutes saying I would get the discount refunded and still receive the free sunglasses. The package also arrived the next day. Top-notch service, I’ll definitely order here again. 👍🏻

Once again pleasantly surprised by the great people at Mystery United. This time with a shirt from closer to home than expected. Cool shirt, great service once again. Also received a pair of sunglasses as a gift. Happy customer here!

Really a great shirt, delivered within a day. I got an Atletico Lusaka Zambia shirt—really good concept and fits true to size.

Everything perfect! THANK YOU.
Super quality and an amazing design.
Keep it up!
Greetings from Luxembourg ;)

For the second time, we bought a Mystery Shirt for our son's birthday. Once again, it was a perfect hit—unique shirts that no one else wears. Ideal for a football fan! You can easily specify your preferences (which shirts you don’t want to receive), and they take this into account. Delivery was fast, and communication via email was accurate.

I had seen advertisements from the company a long time ago and immediately found the idea of receiving a random jersey interesting. However, I hesitated a bit because a box costs around 50 euros.

A few days ago, I finally placed my first order, and I was not disappointed. The delivery took only a few days.

I received an away jersey from a Polish first-division club from the current 24/25 season. It also looks great, so it won’t just remain a collector’s item, but I’ll wear it from time to time as well.

The included info card about the club adds a nice touch. A quick look at the club's fan shop revealed that, when converted from Zloty to euros, the jersey is about 22 euros more expensive than what I ultimately paid at Mystery United.

This won’t be my last order, and I’m already excited to see which jersey I’ll get next.

Fast delivery and I was kept well informed. The product was of good quality.

Fast delevery

Nice shirt, fast delivery

Quality is good, delivery was fast. I live in Austria, and it took less than a week. Price is great, you're doing everything right.

Top quality, exclusive jersey, and a great story about the club. I only order from Mystery United now.

The cards explaining the history of the clubs are really nice. The shirts from Europe are top quality and look great (even from the 3rd division). The shirts from Asia, in my case Indonesia, or Argentina’s 3rd division are a bit simpler, but still very exciting and fun!

I've already ordered over 40 shirts here – always a great experience! The explanation card is a nice touch, the quality is excellent, and the deals are great. Very happy customer!

Tutto perfetto. Proprio come previsto

Very satisfied. Smooth process, received a beautiful Chelsea scarf. It was a gift, but honestly, I would have loved to keep it myself.

My son Thomas loved getting such a surprise. He didn’t know the jersey and looked up everything about it—now he thinks it’s amazing! :)
And the delivery was super fast. He also ordered and received a jersey for his school report—awesome!

Fast delivery, great jersey!

Great concept... Exciting to open the box and received a beautiful scarf!

We gave our kids the Mystery Shirt under the Christmas tree – a real surprise!
A super fun gift, and the card explaining where the shirt is from makes it even better!

Great gift idea for a fantastic price. The process was easy and everything went smoothly.

Reliable, top product, fast delivery, beautiful shirt – all in all, top!

I’d love to order again

A beautiful and original jersey.
Received the shirt in a nice box and neatly packaged.

Unique shirt from Mexico. Met my expectations and still managed to surprise me.
