Transform your rooftop tent into a cosy, insulated retreat with the TentBox Thermal Kit – the must-have upgrade for colder nights and year-round adventures. This clever accessory attaches inside your TentBox to create a quilted, insulated inner pod that keeps warmth in, reduces condensation, and makes your camping experience even more comfortable.
Each Thermal Kit is model-specific, ensuring a perfect fit and seamless integration with your TentBox. Whether you own the TentBox Lite XL, Lite 2.0, GO, Cargo 2.0, or Classic 2.0, there’s a Thermal Kit designed precisely for your tent’s internal dimensions, window layout, and vent positioning.
The Lite XL Thermal Kit provides full coverage for the larger interior of the Lite XL, keeping the whole family warm. The Lite 2.0 version is slim and lightweight, perfect for smaller setups while maintaining airflow through the model’s windows. The GO Thermal Kit uses a lighter insulation profile to match the GO’s compact roof profile, while the Cargo 2.0 Thermal Kit accounts for its extra internal height, fitting perfectly without sagging. Finally, the Classic 2.0 Thermal Kit integrates beautifully with the Classic’s roof liner and LED light bar, maintaining its spacious feel while adding extra warmth.
Installation is quick and simple – the Thermal Kit clips onto the tent’s internal frame in minutes, creating a snug, cocoon-like sleeping space. Built-in windows and doors line up perfectly with your TentBox openings, so you can still enjoy light, ventilation, and views, with anti-bug mesh remaining fully functional. When you don’t need it, just unclip and pack it away until your next cold-weather trip.
The TentBox Thermal Kit is the ultimate all-season upgrade for your rooftop tent, turning chilly nights into warm, restful sleeps and letting you camp in comfort any time of year.
