The Astroman Long Sleeve Sun Shirt delivers lightweight comfort and reliable sun protection for climbing, hiking, and long days on the move.

Made from a bluesign approved recycled nylon blend, it stretches easily, breathes freely, and provides UPF 30 protection through full days outdoors. Quick-drying, moisture-wicking performance keeps you cool under pressure, while hidden snap closures and low-profile pockets add clean, functional storage. A center back hanger loop and raised heat-transfer logo finish the design with a refined, modern touch.
