Arc'teryx Sunna Speed Bird Crew Shirt SS

The Sunna Speed Bird Crew Shirt SS is a technical short-sleeve tee built for high-output days in the mountains. Its 40-denier recycled polyester body uses a Solotex circular knit waffle construction with four-way stretch, delivering excellent breathability and rapid moisture transfer to keep you cool when effort climbs. An antimicrobial finish helps control odour during long, hot missions, and the lightweight 110gsm fabric keeps your pack light without compromising durability.
