They used to be great but they changed the fit for some reason!

I bought my first pair of these 3 years ago and bought many more pairs afterwards because I liked them so much. I've always worn Larges and they were great but the last couple of times I've ordered I've had to return because the Larges are too tight on my legs now. This last time I saw them in the Outlet I decided to buy a few Large and a few X-Large. I'm still returning all of them because the Larges are still too tight in the legs and while the X-Larges fit my legs, the waist is super loose. This is so frustrating because I've absolutely loved these since I found them but it looks like I'm going to have to find another brand as a replacement if there is one.

So good I went back and purchased another 3 pairs!

Very slightly on the small side. Really comfortable and great for sport and outdoor activities.


Wie immer ein Top-Einkauf von UA. Die Hose sitzt sehr gut und hat einen hohen Tragekomfort. Beim Sport ergibt sich eine perfekte Bewegungsfreiheit. Auch beim normalen tragen ist alles perfekt. Keine Nähte die irgendwo drücken und auch beim langen tragen gibt es keine Druckstellen. Alles in allem: Perfekt!

Best shorts ever!

I'm 50 now. I was always looking for the best fitting, high tech en good looking shoirts for me. Not only for sports but for 24/7. I'm 50 now. And I finally found them!

Meilleur boxer

Les boxer under armour sont pour moi ce qui se fait de mieux en terme de confort et de maintien pour la pratique sportive

Hoef geen andere meer

Top product. Zit heel comfortabel en blijft goed van kwaliteit. Ook ben ik zeer tevreden met de lengte. Vind ik vooral belangrijk bij het sporten.

Good product, poor service

I wanted undershorts that would dry quickly after a travel wash & reduce volume of packing / luggage. These are very comfortable & are longer in the leg without being clingy. I ordered the longer length too at the same time and found them to be too warm. UK delivery took over two weeks despite the product showing as in-stock throughout & emails to Customer Service went unanswered - if I were to buy more UnderArmour I'd go through a more reliable third party supplier rather than buying direct, we'll see ...

So good I bought 6 more pairs

Comfortable, good with heat and better at stopping your junk from rearranging.

Guter Kauf!

Sieht gut aus, angenehm zu tragen, nicht zu warm, trocknet schnell, direter Zugriff in den Laderaum, Insgesamt ein guter Kauf.

A new fan!

I love these underwear, and I am quite picky about them. They are really great for sport and walking, comfortable the whole day. I will definitely be buying more.
