Bear Grylls infamously once used a seal carcass as a wetsuit to endure cold waters. Fortunately for the rest of us, he also helped develop the Gerber Bear Grylls Survival Blanket, so we should be able to avoid the seal scenario. This Survival Blanket is lightweight insurance for an unexpected night in the woods. Drawing on Gerber's decades of experience crafting tools and Bear Grylls' adventure knowledge, this is an essential survival tool made better. It's larger in size and uses more robust material than traditional versions, without adding much bulk or weight. And thanks to the durable material, this survival blanket is reusable.
