Best Emergency Blankets & Warmth Gear

Recommended for Power Outage Kit

When the heating fails in a winter power cut, staying warm is about trapping the heat you already have. A good blanket, insulation from the cold floor and a little supplementary warmth go a long way — and cost far less than trying to heat a whole house you can't power.

We've chosen a breathable wool blanket for everyday warmth, a compact foil blanket for the car and grab bag, air-activated hand warmers for cold fingers and toes, and a self-inflating mat to keep you off the cold ground.

Item entry

Wool Blanket

A wool blanket keeps you warm even when damp and won't melt near a flame — the rugged, reusable warmth layer for a cold house, a stranded car or a night outdoors.

Features to look for

A high wool content

The more genuine wool, the better it insulates when damp and resists flame. Blends with a lot of synthetic lose those advantages.

A generous size and weight

A large, dense blanket wraps fully around an adult and holds real warmth — worth the extra bulk for a car or home kit.

Durable, tight weave

A close weave resists snagging and lasts for years of rough use, unlike loose throws that pill and thin quickly.

Common mistakes

Relying only on a foil blanket

Foil blankets reflect heat but offer no padding and tear easily. A wool blanket is the reusable, sit-on-able layer a foil sheet can't replace.

Storing it damp

Put a blanket away damp and it can go musty or mildew. Keep it dry, ideally in a bag, so it's fresh when you need it.
