Marmot Boulder T-Shirt - Short-Sleeve - Men's

An underarm gusset on the Marmot Men's Boulder Short-Sleeve T-shirt shirt relieves restriction in the arms when you're climbing. The free range of motion this gusset offers you lets you concentrate on how to grab that single finger hold instead of worrying if your shirt is going to pull back on you and make you miss it, thus plummeting at least three feet to the ground (we're talking about a really low boulder problem). Marmot built the Boulder with breathable stretch fabric to help keep you cool, and flat lock seams to prevent chafing.
