The Men’s Short Sleeve BENCHMARK Shirt by Black Diamond is built for both wandering up the mountain trails and cruising down to the pub after the day. The all organic cotton body is yarn-dyed and soft to the touch while rugged enough to last. Gusseted underarm panels make sure the shirt doesn’t untuck when reaching or twisting. Two button-flap chest pockets are quick stash storage for small items. The fabric is bluesign-approved.
