This product is a true American size and not slim or Asian size. We have listened to your reviews and completely redesigned our most selling Turtleneck product to resist any fading, pilling, and shrinkage. Made from 100% mid-weight (7.25 Oz) combed cotton with carbon pitched fabric, the turtleneck provides luxurious comfort and warmth for all your outdoor activities. From fabric to fit, this turtleneck offers soft, stretchy and breathable features that significantly increase your comfort level during autumn, winter and spring. The garment fit is just right — not too loose, not too tight and room for extra layering for ski and other outdoor activities in winter. Turtleneck has nicely finished rib-knit cuffs and collar with a dash of spandex, so they spring back to shape.
