The Alpine Bivi from Rab is the go-to solo shelter for climbers and mountaineers looking for a tough and practical all-weather shelter for high-altitude adventures where a low pack weight is key.
The Alpine Bivi features an air-permeable 15D Pertex Shield Air fabric engineered with nanoscale fibres. This radically reduces condensation for a drier, more comfortable sleeping experience.
The outer fabric delivers waterproof protection of 15,000mm HH, alongside air permeability of 0.8 CFM. A waterproof bathtub base with taped seams provides reliable protection against water ingress when compressed.
A wide zipped entry with storm flap ensures you stay protected in all conditions. A tapered design helps keep the pack weight to a travel-friendly 440g while a packed size of just 25 x 12cm makes this technical alpine bivvy shelter ideal for fast-moving multiday expeditions.
