Probably the best bivi bag for climbers wanting a super light and compact design. It is a very lightweight and small-packing bivi-bag made of a lightweight waterproof breathable fabric.
It may not be as breathable as a Gore-tex bag but it's breathable enough, and at around half the weight and half the price, who's complaining?!
The bag does up by means of a draw-cord enclosure. This can be closed down to a breathing hole ca 2cm in diameter. In heavy rain it is necessary to lie face down to stop water getting in but doing this has been shown to let less water in seriously testing conditions than a zipped bag.
The original version was personally tested by Needle Sports' staff in The Himalayas, the Arctic and, worst of the lot, the Cuillins in February. Brilliant!
