What Our Gearhead(R) 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(R) 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.
