Mart Cobra Emergency Mylar Thermal Blankets, 4 Pack
Product Information, Not A Review
Quick Specs
What Stands Out
What To Check
Mart Cobra emergency blankets are thin sheets of aluminized Mylar that reflect body heat back toward the person wrapped in them. They are Amazon's best seller in Camping Emergency Blankets, and each one folds into a flat packet about the size of a deck of cards.
They are built for the cold you did not plan for. A bedroom with no heat during an outage, a truck stuck on an icy road, a soaked kid at the end of a fishing day when the wind picks up.
The Numbers That Matter
82 x 52 in unfolded. Big enough to wrap an adult or tuck over a kid's bed under the regular comforter.
Up to 90% of body heat. That is the brand's claim for how much heat the Mylar reflects back. The simple version: it helps most when it is wrapped close and layered with other blankets, not spread loose over a bed.
4 individually packed. One per vehicle, one for a backpack, and the rest in the house bin.
| Spec | What it decides |
|---|---|
| 82 x 52 in | Whether it wraps an adult |
| Aluminized Mylar | How it holds heat in |
| 4 individually packed | How many kits it stocks |
| Reusable, tear resistant | Whether it survives more than one use |
Safe use. Mylar is a thin plastic film, so treat it like a plastic bag around little kids: never leave a baby or toddler alone with one, and do not let it cover a child's face. Keep it away from open flame, candles, propane heaters and anything else hot. If you are using a heater like the Mr. Heater Portable Buddy, keep the blankets well away from it.
Who It Is For
The dad stocking a truck kit or a winter outage bin who wants warmth that takes up no space. Pair them with HotHands hand warmers, the First Aid Only all-purpose first aid kit and a NOCO Boost GB50 jump starter in the truck, and with a Jackery Explorer 300 at home for lights and phones.

The Short Version
Mylar blankets weigh almost nothing and cost almost no shelf space, so there is no reason not to have one in every vehicle and a couple in the house bin. Layer them under regular blankets in a cold bedroom, and keep them away from heaters and toddlers.
