How much warmth does the Thermal Layer to your tent?

The thermal layer can raise the temperature inside the tent by 10-15°C.

Can I store the thermal layer inside the tent?

Yes, but for the Polaris Lite model, we recommend removing it before closing. This prevents over-compression and ensures a safe, secure fit due to the tent's sleek profile when stowed.
