regret buying it

I usually buy the tactical shirts and it fits a little loose, this shirt runs tight,,,, wasted my money

zu lang, zu glänzend

nicht schlecht, aber leider etwas zu lang und zu glänzend..,


Conforme à la description. La matière est agréable. Bonne absorption de la transpiration!Je recommande.

T-shirt MK1 couleur bleu

Je pense que la coupe du tshirt est trop longue car elle arrive au niveau de mon aine

True to Size

Ive worn this t shirt in the gym several times now and I have to say that its very comfortable gym shirt. Fit is slightly loose for my build around the midsection and a little tighter around the arms. I'm 86 Kg and 185 cm and purchased Large.

Great for workouts

Excellent fit for workouts as its quite long in the waist. Nice quality light material. Only complaint is that the material sticks up slightly on the shoulder where the seams meet.

Fijn sportshirt

Goede pasvorm, zit prettig tijdens het sporten. De kleur was niet afwijkend van de afbeeldingen. Zeer aan te bevelen als je op zoek bent naar een shirt dat strak aansluit.

Fits perfectly

Fits perfectly, very light and good to workout!!!!


Super comfortable, but runs a little looser. If you want a tighter shirt get a size smaller [This review was collected as part of a promotion.]
