This product has great features

What I was looking for

Comfortable, good fix, good quality, just what I was looking for

Long sleeved T

Very comfortable long sleeved T perfect for running in cooler weather

Very nice

Fits great and you don't feels sweaty at a reasonable price!

fits smaller than expected

I've owned lots of heatgear shirts over the years, so I thought I knew what to expect from this fitted shirt. It was a little tighter than other heatgear shirts in the chest, but in the forearms it was so tight as to be unwearable - and I don't have freakish forearms.

Fabulous material.

Durable, strong, and comfortable. Cool to the touch. Easy to wear under a jacket.

TOP Tshirt

maglia tessuto tecnico molto pratica e comoda per allenamento.

not true to size

terrible fit.. i believed your true to fit feature and i felt and looked like a sausage in this shirt. Returning this plus 2 others.....Absolutely no way i could wear this shirt!!!! So disappointed in UA.....

Article conforme à la description. Super haut pour le sport (courses, rugby...) et qui tient suffisament chaud en hiver!

Coupe pour ce maillot parfaite (et ne moule pas trop, donc accessible à toutes personnes même complexée) J'aime tout dans ce haut de sport, car comme dit précédemment, il tient super chaud (surtout en hiver!) et est top au niveau esthétique.

Great top

Great top, fire really well and really comfortable. Good value as well as in sale but things went a bit writing after it was washed and placed in the tumble dryer-don’t do that!
