The Thermal Kit easily attaches to the inside of your TentBox Classic 2.0, creating a warm and cosy sleeping area for year-round adventures.
For easy installation, please follow these instructions.

Step 1: Attach the Thermal Kit
- Unclip the storage net from the roof of your TentBox.
- Use the straps to secure the four top corners of the Thermal Kit to the roof of the TentBox, then attach the clips above the side doors.
Step 2: Reattach the storage net
- If you're not already inside, unzip the window of the Thermal Kit and climb inside the TentBox for the next step.
- Reattach the storage net by clipping it over the top, threading the clips through the holes in the Thermal Kit. This keeps it in place and helps to prevent sagging.
Step 3: Secure the fabric
- Tuck the bottom edge of the fabric under the mattress to keep it snug and in place.
Once installed, you can leave it inside the TentBox all winter, so you’re always ready for adventure.
