Waterproof layer spread under a sleeping bag in tent?

A tarp is an essential piece of camping gear that can be used for a variety of purposes, including providing a waterproof layer underneath a sleeping bag in a tent. A tarp is typically made of lightweight, waterproof material and can be hung under a tent or sleeping bag to protect them from moisture and condensation.

Additionally, tarps can provide extra sun protection when placed over a tent and can add an extra layer of warmth inside a tent by reflecting body heat back in. When choosing a tarp, consider the size of your tent or sleeping bag and the materials that it is made out of.
