Love the fit and feel of this shirt. However, it's not durable at all. After wearing it twice casually, it has a big snag across the shirt. As part of an active line, I expect better durability. I have ten year old Under Armour and Reebok shirts that I've beaten up that still look new.

I LOVE these workout shirts! The brrr is a big upgrade in fanfic over the original RTX shirts - which are still great. I love how these feel.

I have been wearing this under my flannel shirts or under my gi at the dojo.. fits well, and keeps me comfortable. well done Origin

I had a chance to test it on the mountain race, which had various temperature conditions: from +10C in the morning, to 28C in the heat of the day, with direct sunlight and rains. And it worked great! During the rain, it did not become soaking wet and right after rain it became dry again. During peak temperatures, at the sunlight, it was really comfortable and I was not overheating. During morning chill, it was warm. So I would definitely recommend it - this is great all-rounder.

Love this shirt for long rucks in the Texas summer heat. The cooling actually works and feels great especially with a slight breeze!
