Show Description

Add a layer when it's cool or keep the sun off when it's beaming. Solare fabric keeps the chill off without overheating, and when it’s warm shoos moisture off you skin. Clean construction eliminates seams that can rub, and the double-sided silicone elastic keeps them in place. Fold them up, stick them in your pocket and be ready for any big mountain day.

  • Solare polyester and elastane fabric wicks away moisture.
  • Silicone gripper prevents them falling down.
  • UPF 50+ UV protection.
