Clothing Warmers - Arm

DeFeet Armskin SL D-Logo

Similar to the venerable Armskin from DeFeet, however the SL has far less material and a slightly lighter fabric. This combination provides you with a super light and low volume arm cover for days where only the slightest protection from the elements are required.

The Armskin SL outer layer is nylon for an exacting fit, while the inner layer is Coolmax. For those unfamiliar with the Coolmax textile, it doesn't get much better for moisture management. Coolmax is able to take your perspiration and quickly transfer it the outer layer of the garment. The layer next to your skin is now dry again and the moisture in the outer layer dries out quickly from exposure to the elements. Coolmax has many perforations for added air flow, ventilation and body temp regulation. The body of the Armskins also include 10% Elastane and 3% Lycra for optimal stretch that creates a garment that will effortlessly map your arm movements and make them feel like a natural extension of your skin.


  • Perfectly packable
  • Coolmax optimizes moisture management
  • Comfortable seamless construction
