Description

For the days where you need a little extra warmth but not a fully insulated layer, and a little extra weather protection but not a fully waterproof jacket — the Gamma MX Hoody has you covered. More breathable than a hardshell, this softshell offers excellent warmth for little weight and just-enough weather resistance for mixed conditions and colder days. Wear it as a standalone on chilly hikes and approaches, or as a midlayer on cold, wet-weather treks.

What’s been updated: Updated with FC0 material for a lower footprint.
