A light, highly breathable long knee-length leg riding boot sock made in an ecologically aware way, using primarily recycled and upcycled fibres, UpHill Sport \”Summer Course” 3 Layer L2 Socks are designed and manufactured in Finland using a sophisticated multilayered system for durability, warmth and comfort.

The layer closest to the skin is soft polypropylene, able to transfer moisture away from the leg. The centre layer is an R3 tri-blend of upcycled cotton, RPET (upcycled polyester) and Tencel for temperature control, comfort and breathability. The third outer layer is Duratech — upcycled polyamide — for wear-resisting strength.

The leg shaft is kept very thin for the best fit under tight riding boots. The foot includes a breathable mesh upper, shaped, fitted heel, arch grip band in the mid-foot and a seamless toe — especially important in tight fitting boots to prevent rubbing and discomfort.
