Think of this as a footprint for the inside of your tent. Snap it in place where you want it and add a little extra insulation. soft layer. and protector for your tent floor. Perfect if you have a dog that sleeps in your tent and you want to keep the floor abrasion free. Use it outside your tent as a highly water-resistant barrier between you or your gear and wet grass. sand. dirt. you name it. This ultra-versatile blanket packs down into its own pocket and can travel wherever you need it to go.
