Arc'teryx Sunna Crew Shirt LS

The Sunna Crew Shirt LS is a technical long-sleeve tee designed for high-output days in warm mountain terrain. Its lightweight recycled-polyester waffle fabric moves moisture away from the skin, dries quickly, and stays breathable when the pace picks up. Four-way stretch supports unrestricted movement, while gusseted underarms and low-profile thumbholes keep the shirt secure during scrambles, traverses, and approach hikes.
