Tumbler insulation is used to keep your tent, seat, and bed from overheating, keeping your belongings safe and sound.

It is a cheap way to keep an item from freezing to the point where it is unusable, but it can also help keep the temperature inside your tent or sleeping bag as cool as possible.

Insulating your tent is also the easiest way to prevent leaks that can cause condensation, mold, and other issues.
