RAB says about the Storm Bivi
Providing a protective shield from rough weather, the Storm Bivi is suitable for mountaineering, bikepacking, and multi-day treks. Ideal for those travelling light with minimal capacity. Built with two weights of tough nylon and finished with a fluorocarbon-free DWR the Storm Bivi stands up to rigorous use and unpredictable conditions. Fully waterproof with a tough 70D base, it is resilient, hardwearing and highly protective. It has a zipped main entry with breathable mesh panel for added venting, helping to minimise condensation. At 547g and packing down to 25cm x 12cm, it’s easy to stash in a pack for those who get out in all conditions.
