Rab Ark Emergency Bivi Bag

Rab Ark emergency bivi bag for emergency shelter

A lightweight emergency bivy bag in PE that reflects body heat and helps block wind and moisture.

The Rab Ark Emergency Bivi is a lightweight bivy bag for emergency situations. Made from PE (polyethylene), it is built to help you retain warmth by reflecting body heat, while also offering windproof and waterproof protection.

For anyone carrying a simple emergency shelter in a pack, this is the sort of item that is there when conditions turn unexpectedly poor and you need something compact and straightforward rather than a full sleeping system.

What to keep in mind

This is an emergency bivy rather than a comfort-focused sleeping bag or full shelter. It makes sense as part of a back-up kit where low weight and basic protection matter more than space or long-stay comfort.
