THE CAVE stands as Heimplanet’s first inflatable tent, embodying iconic design and functionality tailored for 2-3 people. Its standout feature is the ease of setup—requiring just a pump, this tent can be fully pitched in less than a minute. This is largely due to its innovative geodesic dome construction, which boasts ten crossing points, lending THE CAVE remarkable stability. Constructed from high-quality materials, it ensures weatherproof durability, making it a reliable shelter in various conditions. A key element of THE CAVE’s design is the Inflatable Diamond Grid (IDG). This self-supporting air frame draws inspiration from the molecular structure of a diamond, ensuring both stability and an intuitive setup. This design simplifies the pitching process, allowing users to maximize their outdoor experience without the hassle of a complicated tent assembly. The IDG supports the tent’s waterproof ripstop polyester Flysheet and ripstop nylon inner tent, which also includes multiple storage pockets for organizing smaller items.
The geodesic dome design of THE CAVE not only enhances its stability but also optimizes the surface-area-to-volume ratio. This efficient design principle is complemented by the patented Multi Chamber Safety System, which allows the entire IDG to be inflated in a single step. Once inflated, the frame can be segmented into five separate chambers using one-pump connectors. This segmentation ensures that the tent remains stable even if one section is compromised, providing peace of mind during outdoor adventures. THE CAVE’s architecture includes a star-shaped roof, creating a central support point that enhances stability. This design forms a point symmetrical slope with five drains, efficiently channeling rain away from the tent. The Multi Chamber Safety System not only facilitates a quick setup but also aids in maintenance by making it easy to locate and repair any defective parts. This thoughtful engineering ensures that all struts remain stable, contributing to the tent’s overall robustness.
When first assembling THE CAVE, users will find it consists of three main parts: the inner tent, Flysheet, and Airframe. The initial setup, or First Assembly, involves hooking the Flysheet into the Airframe and then attaching the inner tent to the Flysheet. Heimplanet has made this process user-friendly with clear instructions and color-coded connections. Once completed, the tent forms a single cohesive unit, eliminating the need for managing separate parts in future setups. Heimplanet has significantly improved the fabric quality across their tent range, incorporating 40D High Tenacity Polyester with Double Ripstop. This material offers higher tensile strength compared to regular polyester, resulting in increased tear resistance. Additionally, the new fabric is lighter, drapes better, produces less noise, and feels softer to the touch, enhancing the overall user experience.
Weighing in at 4.8 kg (10.66 lbs) and offering a footprint of 4.8 m² (51.67 sq. ft.), THE CAVE is both lightweight and spacious. Its tent floor is made from 70D Nylon with a durable water repellent (DWR) coating and polyurethane (PU) layer, providing a water column resistance of 5000 mm. This ensures a dry and comfortable interior, even in wet conditions. The efficient design allows for inflation in less than a minute using a floor pump. The durability of THE CAVE is further reinforced by its two-layer air struts. Each strut features an airtight TPU bladder encased in a high-strength polyester fabric jacket. This construction provides the necessary support and stability to withstand various outdoor conditions. Before leaving production, each bladder and strut undergoes rigorous inflation and pressure testing, ensuring reliability and performance in the field.
