Rab Optical Down Jacket

What Our Gearhead® Experts Are Saying:"This is one of the warmest jackets I’ve used in the backcountry. Between the Pertex® Shield, 700-fill down, and TXdown® insulation, it handles gnarly weather without restricting movement. It's like bringing a sleeping bag into the mountains—but way more functional."When we’re heading into cold, high-alpine terrain with real winter conditions in play, we need gear that doesn’t flinch. The Optical Down Jacket is built to thrive in those moments, offering serious warmth and waterproof protection with the mobility and breathability required for backcountry touring, ski missions, or deep resort days.Rab’s trusted Pertex® Shield 2-layer fabric keeps weather out while staying breathable, and the combination of 700-fill-power hydrophobic recycled down and TXdown® Gold sheet insulation keeps warmth locked in without adding bulk or limiting movement. Whether bootpacking to a remote line or navigating an open bowl in brutal cold, this jacket handles the demands of deep winter with purpose-built precision.A ski-helmet-compatible hood, articulated sleeves, removable Matrix™ stretch powder skirt, and strategically placed YKK® AquaGuard® zippers make it clear—this piece is designed to perform. RECCO® technology is built in for added peace of mind, and sustainability notes like reclaimed down and fluorocarbon-free DWR round out the jacket’s forward-thinking design.
