Inspired by the timeless Harrington jacket, this modern track jacket is constructed from lightweight Alpinix™ 37,5 Wool. Combining classic style with advanced performance, it offers lightweight weather protection and exceptional comfort, making it ideal for active days and transitional seasons. 37.5® utilizes natural mineral technology maintaining an ideal core temperature and removing sweat at vapor stage. The technology is embedded into the recycled polyester fiber and will never wash out. Alpinix™ fabric integrates high performance and low maintenance for versatile wear. The fabric features a dry touch and durable texture due to its blend of compact woven wool, 37.5® polyester polyamide and polyurethane, balancing functionality, durability and elasticity.
