POC Layer Merino Neck Warmer Merino warmth that fits under your helmet without a fight Merino wool is the reason this neck warmer works. The fabric uses a blend with over 80% Merino wool in a single-layer knit, so it sits soft and comfortable next to the skin. That matters on a long cold descent where a scratchy synthetic would wear on you mile after mile. The warmer is thin and flexible, making it easy to wear under a helmet for extra warmth in the coldest conditions. It does not stack up at the collar or bunch under your chin. The blend pairs Merino wool with polyamide and elastane so there is real structure to the knit. Four-way stretch gives exceptional freedom of movement and enhances comfort, no matter how you choose to wear it. Wear it as a straight neck tube, pull it up over your nose on a frigid climb, or fold it down when the pace picks up and you start generating heat. One piece, multiple configurations, no extra kit in your pocket. 80%+ Merino Wool Single-Layer Construction keeps the fabric soft against skin and naturally regulates temperature as your effort level changes throughout a ride Four-Way Stretch Knit moves with you in any position, from a tucked aero descent to an upright climb, without pulling or restricting Helmet-Compatible Fit stays thin and low-profile so it layers cleanly under any road or trail helmet without adding bulk at the brow or crown Multi-Wear Versatility lets you wear it as a neck tube, pull it up over the lower face in wind or cold, or fold it down when you need ventilation | Poc | Layer Merino Neck Warmer Men's In Uranium Black | Polyamide/elastane
