Product Description

Product Description

A highly innovative and technical tent, The Cave, from Heimplanet, is a stable and rigid geodesic structure, which utilises flexible TPU beams, filled with air, to support the attached flysheet, meshed inner and groundsheet.

Intuitive and extremely fast pitching allows the interlocking beams to inflate from one of the five valves and only a minute is needed to roll The Cave out, locate a valve, and inflate the diamond shaped frame with the included pump. The innovative design of the tent features a multi-chamber system within the frame, ensuring stability even in the event of any deflation.

Five separate tubes combine to create The Cave’s frame, with the whole tent able to inflate via any section. Once fully inflated the connectors between the different sections can be simply locked off, ensuring any air loss in the frame would only affect a fifth of the overall structure, leaving the flysheet and inner tent still fully suspended and useable.

Weighing only five kilograms, The Cave can comfortably sleep three people, and packs away into its carry bag just as quickly as it was pitched, simply releasing all the valves and rolling the tent back up. The Cave is intended to be a home away from home, allowing new challenges and experiences to be easily sought. Speedy pitching provides owners with more time to do what they love, and the solid structure provides shelter in the most isolated of environments.

The Cave is unique and innovative, and revolutionary in my experience. When I was looking around for an inflatable tent I could not decide whether to get a Vango Airbeam or a Cave, so I bought one of each - a Cave and a Vango Airbeam Velocity 300. Both are 3 man tents, and they each have their strengths and weaknesses. The Cave can be both inflated and pegged out more quickly, since its 5 air beams can be interlinked, so that inflation is done from one point only. The Vango has three thicker, unconnected air beams. Once the Cave is up, unless it is windy, you can ignore the guys. You need to use just 6 tent pegs, mostly to pull the built in groundsheet into shape. Once up, it looks amazing, and always draws comments of interest and admiration!

The Vango Airbeam needs 18 pegs, since the guys have to be used. The Cave has 9 strong pockets inside, including one in the roof, in which to throw bits and pieces. I think the Vango has 4. I was afraid that because of its tiny vestibule (only about one foot deep), heavy rain would drip into the Cave when entering and exiting. Amazingly this does not happen, as I discovered the other weekend. It is possible to open the inner tent, put feet into boots in the vestibule, then unzip the outer, stand up, step away, turn around, and then, without flooding the inner, zip up the outer, at least when the wind is not blowing onto the front of the tent! The vestibule in the Vango is enormous, and has doors either side, so the problem of rain in the inner is highly unlikely.

Two things really bug me about the Cave. Firstly, getting it back into its bag. This is simply embarrassing! Only once, have I succeeded without a huge amount of huffing and puffing to get the air out of the beams. When it is wet this is nearly impossible.

I'll try and keep this briefish as I feel the other reviewers have covered the bases rather well.

Initial setup in the conservatory involves (80%?) inflating the grid/airbeams (tighten all but one of the valves) via the smaller valve with a spike in it. This doesn't take much effort other than trying to keep the pump in the valve (my 16 year old daughter lost her rag a bit when I was timing her setting up). One wrap of gaffer tape around the nozzle seems sufficient but in the field may not be enough. Hang the outer tent to the grid using the toggles making sure that the opening lines up with the only horizontal/ground section with 2 guy lines. Hanging is made easier by not fully inflating the grid. Hang the inner tent (including ground sheet) using the shorter of the two toggles. The longer toggle is used if you only wanted to use the grid and inner tent only(?). You'll be inside the tent when doing this so be careful you're not going to rip anything. There is a rigid strap to separate the inner and outer at the top/centre - I've left this connected (velcro) as I'm assuming it enhances the separation. I've fitted the storage hammock and it'll stay there so it doesn't get lost. There is also a ring in the centre which I believe can be used to hang a light although if you use the hammock there will be some fighting for space. There's no guidance on attaching the guy lines and as it's different to my other tent, I've guessed. There are two toggles and a guyline runner (tension device). I will attach the end toggle to the upper point and the other toggle to the lower point. This will make quite a large loop around the peg but should still tension ok but I'm guessing at the moment and haven't tried it.

The tent is now in it's reusable state and I won't disassemble further.

It is incredibly easy to inflate and I like it. You do always need to peg out the flysheet, this is for waterproofing. There is no overlap between where flysheet stops and waterproof groundsheet turns up. This means that the slightest contact between inner and outer in rain will let water flow into tent. Very easy to do, either some wind or if you push against inner with pillow etc. Pegging out outer pulls it away from inner a bit. I view this as a bit of a design flaw, there should be some overlap between inner waterproof part and outer flysheet. Also you have to pump up tubes HARD (ie really hard) if you want to have stability in wind. I thought I had pumped them up enough but maybe a 40 mph gust collapsed the tubes. No damage and you can just pop them back into shape, but lets water in as there is then inner and outer layer contact, also a bit annoying as you are then in a collapsed tent.

I do like it and the ease of erection/dismantling is great. The only thing I think is a design flaw is no overlap in waterproof sections between inner and outer. Very minorly is that the stuff sack is too small, very difficult to get into. I usually just take home and do it there. The whole point of stuff sacks is that it is reasonably easy to get into and then you can tighten down straps.

If Heimplanet reading this, make a waterproof overlap, only has to be a couple of inches and make the stuff sack 10% bigger.

The Cave arrives (nicely packaged) in three separate sections: the inflatable outer frame, the weatherproof outer tent which hangs from the frame and the inner tent which hangs inside the outer tent. At first the outer frame looks like a deflated spider's web of tubing and straps and it's only as you start to inflate it that it begins to take shape and make sense. It doesn't take long to inflate if you have a capable pump - note that the Heimplanet pump and the Cave tent are boxed separately, so look out for both boxes with your delivery. Mine arrived pumpless - so I huffed and I puffed and I blew my new house up (yes, seriously) and it worked. You can inflate the frame using any one of the inlets, the air circulates throughout the frame and one-way valves on each inlet stop it escaping. The first time you inflate the Cave you have to attach the three parts together, mostly this is just a case of looping toggles through loops, but (in theory) you only have to do this once and every subsequent time you pitch the tent you simply inflate the frame and everything just hangs into place beneath it.

Once it's pitched you can see how incredibly ingenious the design actually is, the outer frame is rigid enough to suspend the tents within but remains pliable - so it just flexes in strong winds like a tree sapling. The two tents hang one inside the other with virtually no contact - this means that air circulates naturally between, the inner tent is partly made with mosquito netting to facilitate this, and in wet weather the outer tent keeps things dry without allowing any seepage.
