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 resilient loft retention. 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. Pertex Quantum Pro Fabric Pertex Quantum Pro uses an ultra-thin water-resistant coating to provide increased protection in rough conditions. By combining a tightly woven face fabric with a microporous coating, Pertex Quantum Pro delivers weather resistance whilst remaining lightweight, soft, and breathable. It’s ideal for use in cold or damp environments.
