Mylar Space Blankets — Best Value
- Reflect body heat (up to 90%)
- Weigh under 2 oz — pack 2 per go-bag
- Also works as ground cover, rain shelter, and signal reflector
Tip: Wrap directly over clothing. Cotton layers underneath improve comfort.
Wool Blankets — Home Essential
Wool insulates even when damp. Keep one per bed during winter storm season.
Car Kit Addition
Store Mylar blankets + hand warmers in the trunk. If stranded, run engine briefly for heat — ensure exhaust pipe is clear of snow.
Bottom Line
Spend $10 on Mylar blankets for every kit you own. Upgrade to wool or sleeping bags for home and vehicle winter prep.
