The Rab Alpine Bivi combines cutting-edge fabric technology with ultralight design for serious alpine adventurers.

Its 15D Pertex® Shield Air fabric features nanoscale fibres that actively reduce condensation, keeping you dry and comfortable through the night. With a robust 15000mm HH waterproof rating and 0.8 CFM breathability, it sheds weather while managing internal moisture.

Built for durability, the bathtub base and taped seams guard against water ingress even under compression.

Pack it down to a mere 25cm x 12cm and you've got the perfect shelter for fast-moving alpine expeditions where every gram counts. Designed for climbers and mountaineers who refuse to compromise between protection and mobility.
