UA long sleeves are really neat & this one is top notch.

Very happy

Great shirt. Very comfortable on a run or just kicking back. [This review was collected as part of a promotion.]

Great looking and equally comfortable

I use these shirts frequently as accents for golf polos, they look amazing and are extremely lightweight and comfortable to the point you forget you’re even wearing them [This review was collected as part of a promotion.]

This product is 100% performance gear.

I love the fabric on this product, it's rugged and I never put my UA gear in the dryer .I always wash it in cold water and hang them up. I have over 60 different shirts. From polos to t shirts to shorts . They all look brand new [This review was collected as part of a promotion.]

Great fit

Love this top, just wish there were even more colour choices so i could get some more. Perfect for running in, incredibly comfortable and a great fitted fit - I'm 6'2" and 93Kg
