Arc'teryx Cronin Cotton Overshirt is a durable and comfortable overshirt inspired by classic workwear, but designed for bouldering and active use in rugged terrain. It is made from a robust blend of organic cotton and nylon that combines natural comfort with stretch and durability. The fabric withstands repeated friction against rock while offering good breathability, making the garment suited to both intense activity and relaxed days away from the climbing wall.

The construction is reinforced with bartack stitching and double needle seaming, which considerably extends the lifespan and makes the overshirt ready for hard use. The regular fit allows natural freedom of movement, and the articulated panels follow the body's movements during climbing and wide reaches. The elbow areas are reinforced without compromising mobility, providing extra durability where it is needed most.

The fabric surface is treated with a PFAS-free FC0 DWR finish that repels light moisture, so the garment retains its comfort and performance in varying weather. The overshirt features a zip chest pocket for secure storage of small essentials, positioned to be easy to reach both on the ground and on the wall.

The Cronin Cotton Overshirt works equally well as a layer for bouldering and climbing as it does as a hardwearing everyday garment, combining technical details, natural comfort and workwear aesthetics in one cohesive design.
