I normally wear Large so I got XL and it fits snug. I will get larger next time because the sizes are Chinese.

For 4 euros, the t-shirt is just fine, I bought 12 and there was a discount, so it came out to 3.60. I am 88KG, 1.86 and wear XL, I got them in XXL and they fit exactly, they have a slim fit so take one size larger. I washed them once so far for testing and they didn't shrink at all, now it will show in the coming months. The cotton is of good quality and thin, I think they will last me through my service without any issues.

I normally wear XXL but I got XXXL so that it would be the length I wanted, which so far has not faded in the washes, but very nice fabric

The size and quality of them are just fine. They are almost identical to the ones they give you in the army.

Note: I bought the same size as the ones they gave me in the army.

For their price, they are fine.
Generally, they are tight, one needs a bigger size than they normally wear. Also, they shrink a bit in the wash.

5 stars because it can't get any cheaper.
€2.5 per t-shirt.
I bought 2 packs so I can change without waiting for the washing machine.
