The Rab Men's Khroma Transpose Jacket is a waterproof, synthetic insulator designed specifically for ski mountaineering. Rab's Proflex membrane maintains robust waterproof, breathable ratings to shield you from wildly wet weather, while Primaloft Silver insulation ensures warmth even if it happens to get wet. The hood is large enough for ski helmets, and there are plenty of adjustments at the hood, hem, and cuffs to seal out spindrift. Even without the hood overhead, the jacket's back neck stretches snugly so snow can't sneak inside. Rab designed the Khroma Transpose with a regular fit and sleeve articulations so you can swing ice axes and bootpack with a full range of motion.
