Mountain Equipment Aerotherm Jacket £200
Designed for mountaineering, alpine climbing, hiking, and running, the Mountain Equipment Aerotherm is a highly technical, ultralight softshell jacket. It features a super-light double weave softshell outer and a micro-grid of fleecy squares inside, providing warmth and weather protection. Its minimalist design weighs only 279g in men's small, making it ideal for gramsaving hikers. The jacket's outer is Exolite 45 stretch double weave softshell fabric, the lightest double weave fabric globally. The inner micro-grid (100% polyester) offers wicking and temperature regulation. Despite its low weight, the fabric maintains decent toughness, though it lacks the stretch of traditional softshells.
The jacket copes with light showers and wind, but for heavier conditions, pair it with a waterproof shell. Its breathability is exceptional, ensuring comfort during fastchanging conditions. With a snug, athletic cut and articulated, pre-shaped sleeves, the jacket fits well but may require sizing up for some. Notable features include two fleecelined handwarmer pockets, a chest pocket, adjustable waist hem, and elasticated wrist cuffs. The main YKK zipper has an internal
storm flap and a zipper garage but is oneway. The hood, with an elasticated rim, is adjustable via a rear drawcord. The jacket can be stuffed into the right-hand pocket, creating a compact package with karabiner carry loops for easy access.
