"What Our Gearhead® Experts Are Saying:""This is my go-to shell for big storm days and deeper missions. The GORE-TEX ePE is super burly but lighter than I expected, and the fit is dialed for layering. That longer cut really helps in deep snow, and RECCO is a peace-of-mind bonus.""When we're pushing into remote alpine terrain, we need gear that keeps up. The Khroma Diffuse GTX Jacket is Rab’s dedicated big-mountain shell—built to handle deep powder, burly storms, and long ascents with confidence. Its 3-layer GORE-TEX with the new ePE membrane delivers bombproof waterproofing and breathability with a lighter, more sustainable profile. We count on the long cut and articulated sleeves for full coverage and mobility during technical skintracks and steep descents. The helmet-compatible hood cinches tight without fuss, while the removable powder skirt and RECCO® reflector bring versatility and safety for big backcountry days. Whether we’re charging couloirs or linking ridgelines, this jacket’s the top layer we trust when weather and terrain get serious."
