TUFF-TREK® Ultralite XL Thermal Liner
Stay warmer. Sleep better. Camp longer.
Upgrade your camping comfort with the TUFF-TREK® Roof Tent Thermal Liner, designed to improve insulation and reduce condensation inside your roof tent during colder conditions.
Thermal liners create an insulating air gap between the tent canvas and sleeping area, helping retain heat while also reducing moisture build-up overnight. This makes them ideal for winter camping, shoulder-season trips and colder climates.
Compatible with many soft top roof tents, the thermal liner installs easily inside the tent and can remain fitted when the tent is closed.
