Garneau M Drytex 4000 Zip Top F17

This heavyweight base layer is made with Drytex® 4000, a technical fabric that is brushed on both sides to create a thick insulation layer of air that retains body heat, and Mesh, a fabric that provides incomparable comfort and flexibility as well as maximal breathability. The reversed 8"/20.5 cm zip with inner flap and zip garage makes it easy to slip on and off, and the flatlock seams eliminate irritation and reduce chafing for even more comfort.
