Inspired by climbers, then refined to perform across a broad range of alpine activities, the Delta is a go-to when thermal efficiency, stretch, and all-mountain versatility are required. The Polartec® Power Dry® fleece’s voided grid construction delivers a high warmth to weight ratio and provides outstanding freedom of movement. Performing as a midlayer in cold conditions or a standalone in cooler temperatures, its versatility and comfort make it an essential piece of any mountain kit. This model is an updated design of the Delta LT Jacket with a revised fit and warmer fleece. Arc'teryx Women's Delta Jacket | Alpine Country Lodge | St. John's NL
