Modest, hidden from view, and ready to regulate body temperature at a moment's notice, the summer base layer is often considered a secondary item. Not so with us, who constantly strive to perfect its materials and fit to ensure maximum comfort during the hottest days of the year.

Starting with the numbers, the NS Skin Layer is approximately 30% lighter than its predecessor, the SkinFoil. Made with our Circular Seamless technology, the fabric has no irritating side seams because it's a seamless tubular knit that feels ultra-soft against the skin. The Skin Layer features a blend of carbon fibers and polypropylene, which manages moisture much better than previous versions. The result is an ultra-lightweight, breathable, and antibacterial base layer that keeps you as cool and dry as possible.
