Bringing you the optimal blend of low weight, warmth, and protection, the Rab Electron Pro Jacket fights off cold weather so you can continue climbing or skiing comfortably. The Electron Pro excels on winter ice climbs, summer alpine endeavors, and shoulder-season multi-pitches. Light and lofty 800-fill down insulation equips the Electron Pro with midweight warmth, and Nikwax's hydrophobic water-resistant treatment helps the down retain its lofty warmth in moisture. Rab wrapped up this protective insulation with Pertex's highly water-resistant, breathable, and wind-repellent Quantum Pro fabric. The hood cinches down over beanies or helmets with ease, and Rab added a wired peak to stay out of eyesight while you belay.
