Mountain Equipment Aerotherm Women's Jacket

A lightweight, windproof, and fast-drying jacket that adds a touch of warmth—ideal for mountain running and hiking.

Many within the Mountain Equipment team reach for the Aerotherm Jacket when heading out for brisk-paced days in the hills under moderate conditions. Recognised as one of the most adaptable jackets in their collection, it effortlessly balances wind resistance with moisture management, making it an excellent choice for a wide range of mountain pursuits. Whether climbing, hiking, or running, this jacket is designed to be worn comfortably all day.

The Aerotherm is crafted with a wind-resistant EXOLITE 45 double weave soft shell as its outer fabric. Light in weight, breathable, and with a touch of stretch, this material shields against the wind while allowing for free movement. Inside, a soft micro-grid lining with high wicking performance draws moisture away efficiently during steep ascents, helping to reduce discomfort from sweat build-up. This inner layer also contributes a measure of warmth when navigating chilly ridges or exposed summits. The combination dries swiftly and ensures all-day comfort, even in stop-start mountain conditions.

Tailored with a close-fitting Active silhouette to reduce bulk, the Aerotherm fits neatly beneath a waterproof shell when the weather turns. The hem can be adjusted via a drawcord to refine the fit, and low-profile elastane-bound cuffs help to seal out wind. A Mountain Hood with elastic binding delivers dependable protection during windy runs, yet stows neatly away when not needed. The inner lining is reversed in the arms to avoid snagging when worn with other layers, while the articulated sleeves allow for freedom of movement during climbs or scrambles. Two zipped hand pockets and a zipped chest pocket provide space for essentials, and the jacket packs into its own hand pocket with twin loops for clipping to a harness or rucksack.
