The latest generation of this popular fold-out roof tent impresses with an optimized design and improved everyday usability. The rounded frame ensures that rainwater drains reliably instead of collecting on the tent. Large window areas, a roof window, and the cabrio function create a bright, airy interior and bring you closer to nature.
Sleep in comfort at the highest level
With a sleeping area of approx. 240 × 180 cm, the roof tent offers plenty of space for up to four people. The memory foam mattress provides excellent sleeping comfort, while the aluminum honeycomb base ensures stability and additional insulation.
Thermal inner tent – more warmth, less moisture
The thermal inner tent significantly improves insulation inside the roof tent. It retains heat more effectively while reducing condensation. Thanks to its breathable properties, it creates a comfortable interior climate. Installation is quick and easy using the existing attachment points.
Roof tent with annex – your mobile living space
The high annex expands your setup with a spacious, protected area next to your vehicle. It offers plenty of room for sitting, cooking, or storing equipment and can also be used as an additional sleeping area. With door openings on all four sides, you remain flexible and can access your vehicle while staying dry. The durable PVC floor reliably protects against moisture and can be removed if needed.
Flexible for different vehicle heights
With a mounting height of approx. 160 to 220 cm and additional height adjustment, the annex adapts perfectly to different vehicle types – ideal for SUVs, vans, and taller setups.
Thoughtful details for life on the road
Organizers, shoe pockets, and a cargo net keep the interior tidy. The optimized folding mechanism and gas struts make setup and takedown easier while ensuring the tent fabric is stored neatly.
