Best Emergency Shelters & Bivvies

Getting out of the wind and rain is the fastest way to stay safe when you're stranded or caught out. In the damp British climate hypothermia can set in quickly, even in summer on the hills, so some form of shelter belongs in every kit and car.

Our picks run from a pocketable foil blanket for every bag, through a reusable survival bivvy and a rain poncho, up to a versatile tarp you can pitch as a proper shelter — match the weight and protection to how far from help you tend to be.

Item entry

Bivvy Bag

Waterproof emergency sleeping bag that provides shelter from wind, rain, and cold. More durable than an emergency blanket.

View item →

Features to look for

Breathability

Cheaper bags cause condensation. Look for breathable membranes like Gore-Tex or eVent.

Weight

Emergency bivvies: 100–200g. Reusable quality bivvies: 300–500g.

Zip access

Full-length zips make getting in and out much easier.

Common mistakes

Not practising getting into it

In an emergency, fumbling with a bivvy bag wastes precious body heat. Practise at home.
