You're not a snake, so why shed layers every time you ride Regulate your core temperature with a functional base layer that keeps you warm and dry. The Gore Base Layer Men's Turtleneck Shirt is the perfect addition to your cold weather cycling kit. A base layer is not just extra fabric. It has two functions first, it provides a smooth, seamless layer between your skin and outerwear, and second, it wicks moisture from perspiration away from your skin keeping you dry. Gore's turtleneck features a soft brushed polypropylene material which, combined with the form fit cut, feels like a second skin. It also transports moisture quickly to the outside so that it evaporates through a breathable outer layer. Layer the turtleneck under Gore's Power 2. 0 Thermo Jersey for optimal warmth and ventilation on cool wintery days. In frigid cold, add the Gore Power GT AS Jacket and ride until the sun sets. A half length zipper with a camlock adds a extra bit of adjustable ventilation for those long climbs that take everything you've got. The collar is close fit and a zipper garage prevents chafing. The turtleneck's seams are flatlock stitched for comfort and the back is elongated to stay tucked into your tights.The Gore Base Layer Men's Turtleneck shirt is available in five sizes from Small to XX Large and comes in Black and White.
