The Rab Storm Bivi bag is a great budget bivi. The bag is full closure and completely waterproof, however the material used is not particularly breathable. This can lead to a condensation build up which can limit the effectiveness of down sleeping bags. This makes it a good option for infrequent use or one off expeditions such as Duke of Edinburgh Awards. It comes in a waterproof stuff sack so even if your bag gets wet in the day, your bivi remains nice and dry!
The Storm Bivi is a light-weight single-person bivi, in a 70D Hyperlite Storm fabric, for trekking and travel use.
The Storm Bivi has been a regular in the Rab® shelter collection for many years, and continues to offer the same high levels of protection and durability. Designed to be compatible with all the wide' style Rab® sleeping bags, the Storm Bivi features an end zipped entrance and a small mesh panel for venting.
It will pack down to just 13cm x 25cm (5 x 10inch) for quick-and-easy packing and transporting.
