Whether we're on a hanging belay or pushing toward a summit, Rab's Xenair Alpine Jacket is delivering the coverage we need. The Pertex Quantum Air fabrication fends off sprindrift, lets our microclimate breathe, and holds strong against rough terrain, while the synthetic insulation dries quick in wet conditions yet still traps heat when wet for reliable warmth, even when we're standing still. To hide from the wind, we pull the hood over our helmet, tighten the cuffs over our gloves, and cinch the hem, locking all our warmth inside.
