The HMK layering system is designed to work with our XR Weatherproofing system to keep you out riding longer with more comfort. HMK base layers use exclusive EC2 Qwik-Dri technology to wick moisture away from your body to keep you dry and warm. The destination mid-layer offers 250 grams moisture wicking polyester with a smooth exterior for easy layering and a soft brushed interior for added comfort. HMK's destination mid-layer: comfortable, dry, warm, and soft.
