Had the Shrit on an 8-day trek to the Alps, rain, wind and sun has felt. It's really very convenient, but with all the cushions I expected a bit more. I still get on the hips chafing. (Not on a bad backpack, Deuter Air Contact 70 + 15 is as well padded). Is not the fault of the T-shirts, but am the usual - had hoped for more just because of the special design. That's why 1 star deduction with regard to the price .. Think for price / performance ratio you can get better.
Did not notice much of a difference to my Under Armour shirts that do not have all the bells and Schack on hips and shoulders and back, and that cost less.
Had the shirt also for training at the gym. There is also great. One can purely sweat without it stinks, it looks great and has a cooling effect.
Another bonus is relatively long, and can be pulled further down, so stuffed into his pants with belt and remains wonderfully on the spot.
