DeFeet Armskin D-Logo Wool

Many seasons have passed since the introduction of DeFeet's Armskins arm warmer, and now it finally gets a new identity and build, with the use of wool. The Merino Wool blend is time tested as an insulating, wicking fabric and is surprisingly durable and effectively long term if cared for properly. The Merino is complemented by nylon fibers and Lycra for structure, moisture release and just the right amount of stretch. Excellent for cycling, running, and hiking, the DeFeet Armskin D-Logo Wool should be a mandatory piece in the wardrobe of every endurance athlete.
