RAB Alpine Bivi

The Alpine bivi is a minimalist, single-person waterproof bivi, designed for use on lightweight alpine expeditions and summit attempts.

The air-permeable 15D Pertex Shield Air fabric is engineered with nanoscale fibres for radically reduced condensation and a drier, more comfortable night. The outer fabric has waterproof protection of 15,000mm HH, alongside air permeability of 0.8 CFM. The tent features a waterproof bathtub base with taped seams providing reliable protection against water ingress when compressed. It also features a wide zipped entry with storm flap which enables you to stay protected in all weathers. While the bag measures 230cm in length and 80cm at the shoulder, the sculpted cut reduces the all-in weight to just 470g. With carry-friendly packed dimensions of 25cm x 12cm, it’s the ideal way to stay fast, free and agile on multi-day alpine expeditions.
