Rab Alpine Bivi

The Alpine bivi is a streamlined, single-person waterproof bivi bag, crafted for lightweight alpine expeditions and summit pursuits.

Constructed from air-permeable 15D Pertex Shield Air fabric, the material incorporates nanoscale fibres to significantly minimise condensation, ensuring a drier and more comfortable night’s rest. The outer layer offers 15,000mm HH waterproofing alongside an air permeability rate of 0.8 CFM. A waterproof bathtub-style base with taped seams guarantees robust defence against water ingress, even under compression. The bivi also includes a spacious zippered entry with a protective storm flap, offering reliable shelter in all weather conditions. Measuring 230cm in length and 80cm at the shoulder, its sculpted design reduces the overall weight to an ultra-light 470g. With a compact packed size of 25cm x 12cm, it provides a practical and agile solution for multi-day alpine adventures.
