With its zoned baffles, high-loft goose down and ascent-ready feature set, our Electron Pro Jacket makes mountain-grade warmth and protection packable, portable and flexible. As part of our Ascent range, the Electron Pro Jacket is designed for winter insulation, alpine climbing and year-round mountain use. The lightweight outer is built from 20D Pertex® Quantum Pro ripstop nylon with a DWR coating for improved weatherproofing. Zoned midi and micro baffle stitch-through construction helps minimise bulk, eradicate cold spots and increase core warmth. The 800FP goose down is treated with a Nikwax® hydrophobic finish for coping with moisture. Other key features include stretch-panel cuffs, a helmet-compatible hood with stiffened peak and a pair of harness-friendly YKK® zipped hand pockets. With its premium down, advanced fabrics, and active fit, our multifunctional Electron Pro Jacket strikes the ideal balance between warmth, weight and mountain utility.
