  • SET UP - With our tents you only need to connect the airframe, inner tent, and outer tent once before your first use. After that your tent can simply be rolled out like a sleeping bag, pumpen up and fixated with pegs in case of strong winds. To pack up simply open one of the valves to deflate the airframe and roll up the tent to put it back in the pack sack.
  • ONE PUMP SYSTEM - The airchambers of the frame are connected. That way, the entire tent can be pitched using only one valve. After the tent is pumped up within few seconds, disconnect the airchambers using the small clips attached so that the tent remains stable even if one airchamber is damaged (Multi Chamber Safety System).
  • STABILITY - Thanks to the geodesic frame structure our tents are extremely stable. Even our largest tent can withstand windspeeds up to 110mph.
  • ROOF DESIGN - The tent's centre becomes an additional supporting point. This allows the formation of a star-shaped roof. The result is a point-symmetrical slope that offers five run-offs for rain.
  • FACTS - Packing Size: 16x13x9in, Weight: 10.6lbs, Ground Area: 54 square feet, Double-layer air struts, 5000mm water column, see Heimplanet Groundsheets for extra floor protection.


Developed with passion and attention to detail in Hamburg, Germany.THE CAVE is our first inflatable tent and it still is an icon. All it takes is a pump and in less than a minute your tent will be pitched. Thanks to its geodesic dome construction with ten crossing points THE CAVE is extremely strong and because it is made from high-quality materials it offers weatherproofness and durability too. The Inflatable Diamond Grid (IDG) s stability and an intuitive and easy setup of THE CAVE so you can get the maximum out of your trip. It provides support for the waterproof RipStop Polyester fly sheet and the RipStop Nylon inner tent with lots of storage compartments. The vestibule is good for storing smaller things or your shoes. The gear loft under the inner tent roof offers added storage - put your lamp inside and create a diffuse and ambient light inside THE CAVE. For everyone who loves travelling and simplicity! Inflatable frame, inner and outer tent work as a unit and only need to be assembled on the very first setup. From the second time on you just need to pump it up.

  • I recommend.
Color: Classic
As far as backpacking tents go this tent is by no means traditional. I am a bit hesitant on giving this tent a full 5 stars, but I feel as if for each negative it has an amazing positive. I have spent about 25 nights in this tent and have loved it. The first thing you notice when setting this tent up backcountry is how easy it is. You literally open the valves and pump it up and steak it down. The average time is around 6-10 minutes. This is also equally easy to take down but on average without trying to hurry can be take down in around 15 minutes. The negative with how this tent folds up is that any water not shaken off gets folded up in it and can be aggravating Because the rain fly and inner netting and tube frame are all one unit after you put them together. So this can make it difficult to clean because to separate each part and shake it out is not easy but can be done after the trip at home pretty easy. The second positive is how amazing this tent handles wind. With living in Wyoming and frequenting Colorado and Montana for backcountry trips the wind can get pretty crazy in the mountains and this tent takes it all. the negative is that the vents on the tent can't be closed from the inside and don't 100% seal when closed. Thus a little wind gets in always. Next is the weight of the tent. The tent is very light for a tent of this size, and it does fit three different 6 foot tall college men with backpacks shoved to one size of the tent, this tent is very nice for coming in at 10ish pounds. ( depending on the pump you get). The con here is that even being light the tent still is pretty large when folded down into its compression sack. About the size of two compressed backcountry sleeping bags. so the trade off of weight and ease of set up is countered by the size that you have to strap to your pack. One thing compared to other tents I have used is that there are almost no vestibules only two small ones for boots) thus all backpacks have to be stored inside the tent. This is a minor inconvenience because there is so much floor space but it is one that also has benefits that you wouldn't think of with a normal more square footprint of a tent, these are that you can access anything in your pack easy and not have to unzip doors to get at it and in cases of uneven terrain you can use your pack as a leveling piece kinda like a giant wedge pillow. All in all with this nontraditional tent you get a very nice tent that sets up fast and handles wind, rain, and snow well. ... show more

  • Finally, relief from threading aluminum poles every day.
Color: Classic
The media could not be loaded. I go on bike tours. That means setting up a tent, and striking it, and moving on to the next spot, over and over again. After a while, folding up and threading aluminum poles (especially in the dark!) becomes a huge annoyance. So I got this tent. This tent is all one piece, including the optional groundsheet. I just unroll it where I want it to go. When I'm packing it back up, I open the valves, fold the sides in, roll it up in one direction, and then unroll it and roll it back up in the other direction. This drives out almost all the air, and I can then stuff it into a large compression sack or directly into an extra-large pannier. Easy and fast. The compromise I'm making for this convenience is of course the weight. This weighs about 50% more than most other tents of similar size. Given how important weight savings is on a bicycle, that makes this a tougher call. My dream was to find a portable device that I could attach to this tent, and have it inflate automatically. But all the portable inflators (and I've looked at dozens) have one of two defects: They do not make enough air pressure, or they are slow and loud as heck. You can't show up at a nice calm campground with other people nearby and then start a device that goes BRPRPRPRPRPRPRP for 20 minutes. You'd get pelted with granola. I also thought about getting a full-size floor pump to inflate this thing, but it's too bulky to carry on a bike. So I gave up, and got the smaller Heimplanet-branded handheld pump. Turns out, that small pump is pretty darned efficient. I'm able to inflate the tent in a little under 3 minutes, without much effort. I've attached an 8x speed video to this review. Two other relatively minor complaints: The front door is a bit small, and when the outer rain cover is in place, it's a bit dark inside. ... show more

  • Fantastic! Very sturdy tent when assembled.
Color: Classic
This is a surprisingly sturdy tent when assembled. It is the sturdiest tent I have ever slept in. The first time we camped with it we were basically in a wind storm, and it kept us really well sheltered. Everyone else had standard dome tents that were totally flattened by the gusts of wind, and our tent didn't even move! It's a rock! From the car I was able to get this thing unpacked and assembled and inflated in less than 10 minutes without even rushing. When I was done camping, I was able to deflate and pack the tent down in about 15 minutes! It's a bit more work than inflating, as you have to roll it to deflate, then unroll and repack it, but was still quite easy to pack. The only disadvantage is that it is a little bit bulky when packed down, even though it is quite light. Also, this NEEDS to be staked down, that is really a requirement compared to other tents. The interior looks awesome (as the the space age exterior), and it has a ton of headroom. We put a queen-sized inflatable mattress in the bottom, and there's still room for your bags too. All in all this is a 10/10 tent. I love it! ... show more

  • Initial setup sucks.
Color: Classic
Three stars because I really like this tent. Also, only three stars because the first setup is a monumental pain in the ass. Took over two hours for first assembly. The crappy toggles are very difficult to engage and getting the inner and outer tent properly oriented is tedious. I was off twice and had to detach everything and start over. The instructions were piss-poor. No guidance on which toggles went where. Thankfully, I’ll never have to do this again. ... show more

  • I love my tent. Gets really hot in the day though.
Such an amazing tent so worth the money it’s only problem is that it should have a better way to ventilate.

  • Finally found what i really needed!!
Best tent I have here. Great design. They were out of stock once I ordered it but got asked to replace with the black camo limited one instead which is unbelievable beautiful.

  • Nice tent but won't fit three people
Color: Classic
Nicely made tent but too small for three people as advertised so I sent it back. Perfect size for one person, two can fit but tight. Three if only all kids.
