I wore the shirt for 2 days in the Andorran mountains riding downhill with my friends. I had many crashes and on the second day I crashed right into the side back on one of the trails and the shirt held up perfectly showing only impregnation marks from the dirt and the grass I crashed into.
I could also wear my elbow guards (I have the FOX launch Pro) under the shirt. Very comfortable and roomy enough to do tricks on the trails and allows plenty of movement.
Buttons are big and durable with a very ergonomic design, and close / open really nicely.
Would definitely carry this shirt around on future riding trips!
