Icebreaker's heavyweight baselayer with hood with optimised fabric zones for active performance. 

The Men's Winter Zone Long Sleeve Half Zip with Hood is a technical top for skiing, winter climbing and other highly active days in cold conditions. Zoned body mapping technology help optimise thermal regulation while the front zip allows for easy dumping of heat.

Strategically placed lightweight eyelet merino mesh under the arm panels actively controls temperature during high output pursuits, while the main body features Icebreaker's BodyfitZONE merino wool fabric with a touch of LYCRA for stretch. Merino and Polyester waffle jersey has been added in key areas around the forearms and hood for added abrasion resistance.

The addition of flatlock seams throughout the garment eliminate chafing, and the protective hood fits comfortably under any helmet.
