Inspired by the colours found around us in the glacial elements. The new Glacier Ultra Light Sock is a high performance, low volume sock for a precision fit with a design to suit. The Definitive Fit System delivers a close form fit and is coupled with light cushioning over the shin area for extra comfort in this high impact zone. Made from the Signature Blend, a luxurious combination of merino wool and rayon from bamboo, the ultra light weight rating of this sock offers exceptional breathability, superior warmth and comfort.
