Pushing through fast-paced, sun-drenched days on the open trail is no sweat in the Sunshield 1/2 Zip. This super-light, mobile shelter from the sun combines broad-spectrum UPF 50 protection with HeiQ Mint anti-odor treatment for a go-to top that'll keep you feeling and smelling fresh in sweltering conditions. Sitting super-light on the skin, the stretchy, durable fabric construction offers unrestricted movement through high-effort sections, and packs down easily when not needed. This is your no-brainer layer for afternoons spent top roping on exposed faces, hikes on less-than-shady trails, and sunny weekends crossing rivers.
