The 260 Zone LS Half Zip is a warm base layer top that features optimised fabric zones for active performance during highly-active adventures in cold conditions. A touch of LYCRA® adds stretch, mesh eyelet in the underarms and upper back actively control temperature when you're pushing yourself and a jersey waffle in high-wear areas adds abrasion resistance. To top all this off, you can make small adjustments in temperature using the front zip and raglan sleeves and flatlocked seams add chafe-free mobility and maximise comfort.
