The Heimplanet Cave XL is the world's most advanced inflatable tent, combining revolutionary geodesic dome technology with genuine four-season capability. This isn't just another camping shelter. It's a tent that inflates in under 60 seconds using a single pump valve, yet delivers the structural strength to withstand Iceland's notorious storms, Scottish Highland winters, and everything nature throws at you.
The Cave XL's strength lies in its patented Inflatable Diamond Grid structure — a sophisticated system of five air chambers creating ten intersection points in a geodesic dome configuration. This design distributes stress evenly across the entire structure, delivering exceptional stability that traditional pole tents simply cannot match. Each air strut features durable two-layer construction with an extra-airtight TPU bladder and high-strength 140 HPE Dacron outer jacket.
Four-season capability means serious weather protection. The flysheet carries a 3000mm hydrostatic head rating for genuine waterproofing, whilst the floor handles 5000mm — built for prolonged downpours and melting snow alike. The fabric itself is 40D High Tenacity Polyester with Double Ripstop construction. The winter inner tent uses solid ripstop nylon rather than mesh, blocking wind and cold effectively whilst multiple ventilation openings prevent condensation without sacrificing warmth.
Heimplanet's Multi Chamber Safety System provides genuine peace of mind in remote locations. After the initial one-valve inflation, you close connecting tubes between the individual air chambers. If one chamber is damaged, all other struts remain fully pressurised and stable. The tent maintains structural integrity whilst you locate and repair the affected chamber — every single bladder and strut is pressure-tested before leaving the factory.
Setup couldn't be simpler. Roll out the tent, connect your pump to the single valve, and watch the entire structure rise before your eyes in approximately 27 seconds of pumping. The initial First Assembly permanently connects the flysheet to the airframe and inner tent to flysheet using colour-coded attachment points. From then on, it's genuinely roll out, inflate, and you're done. No poles to thread, no sleeves to wrestle with, no guesswork.
Inside, the Cave XL offers 5.4 square metres of footprint with 4.1 square metres of inner tent space. Three people sleep comfortably with space for gear, or use it as luxurious accommodation for two with bags stored inside. When packed, the entire system compresses to 26cm x 51cm x 24cm and weighs 5.4kg — remarkably compact considering the internal volume and four-season capability it delivers.
The complete package includes the winter inner tent, pump, repair kit, carry bag, and lifetime warranty coverage on manufacturing defects.

If the competition reaches its entry limit before the closing date, it may close early, and this will be made clear here on the page.

Our focus is always on the prize itself, and in our case, that means the campervan. We believe winning a campervan is a genuinely exciting, life-changing prize, something that opens up new experiences rather than simply landing as a number in a bank account.
Because of that, we generally shy away from cash prizes or cash alternatives and leave those to other competition sites. For us, the appeal is in the adventure, the freedom, and the memories that come with owning a campervan, and that’s what our competitions are built around.If a cash alternative is ever available for a specific competition, it will be stated clearly on this competition page before you enter.
If it’s not mentioned here, then the prize is the campervan as described, with no cash alternative offered.Our aim is to be upfront from the start, so you can decide whether this competition is right for you before taking part.
Fairness is non-negotiable for us, and we’ve built the draw process to be as clear and consistent as possible. When a competition reaches its closing date and time, entries are locked and the draw is run automatically using a Random Number Generator (RNG).
In plain English: every valid entry is assigned its place in the draw, and the RNG selects the winner from that pool. No judgement calls, no manual picking, and nothing “behind the curtain”.Because the draw happens only once the competition has closed, everyone is entering under the same rules and within the same window. We also keep a proper record of the draw outcome so the process is traceable if it’s ever queried.
If an entry doesn’t meet the competition rules (for example, it exceeds entry limits or fails eligibility checks), it won’t be treated as a valid entry for the draw.If your entry wins, you’ll be notified immediately by email.
If we don’t hear back from you via email, we’ll follow up using the contact details you provided at checkout, which may include a phone call, text message, or WhatsApp.
The idea is simple: if you’ve won, we’ll do our best to reach you quickly so you can enjoy the moment and we can move things along smoothly.
Yes, we do offer a free postal entry option, in line with competition requirements.Postal entries are limited to one entry per household, per competition, per month, and must be submitted exactly as outlined in our instructions.
This includes providing the correct details, meeting the eligibility requirements, and ensuring your entry arrives within the stated timeframe. Any entries that don’t meet these requirements won’t be included in the draw.Because postal entries rely on delivery times and manual processing, they naturally take longer to handle and don’t come with instant confirmation.
For that reason, most people choose to enter online, where entries are confirmed immediately, easier to manage, and give access to better value options such as Subscribe & Save.
Postal entries are included in the draw in the same way as online entries, provided they’re valid and received on time. Full instructions are available on the website for anyone who wishes to use this method.
If this competition reaches its maximum number of entries before the listed closing date, it may close early. When that happens, entries are locked and no further entries can be accepted, even if the original closing date has not yet passed.If the competition does sell out early, this will be made clear on this page, and the draw will still take place as scheduled for that competition.
Selling out early doesn’t change how the draw works or how the winner is chosen, it simply means all available entries have been taken.For anyone planning to enter, it’s always best to do so sooner rather than later, especially on popular competitions that can fill up quickly.
Once you’ve entered a competition, everything is kept clear and easy to follow. You’ll receive email confirmations for your entries, so you always have a record of what you’ve entered and when.If you choose to provide a mobile number at checkout, you’ll also receive text message confirmations and updates, giving you extra reassurance that your entry has gone through successfully.
This helps make sure you don’t miss anything important.We’ll continue to keep you updated by email with key information such as competition reminders, closing dates, and winner announcements.
If you’re part of Subscribe & Save, things are even simpler, as your entries are handled automatically and updates arrive without needing to re-enter each time.Our aim is that you always know where you stand. From confirmation through to the draw result, everything is communicated clearly, so you can enjoy the experience without second-guessing anything.
Once the winner has been confirmed and we’ve made contact, we’ll arrange the next steps directly with them. The exact handover details depend on the prize, and everything will be explained clearly so there’s no uncertainty.If the prize is a campervan, we’ll work with the winner to agree a suitable collection or delivery arrangement.
Timescales, location, and any practical details will be discussed in advance, so everything is handled smoothly and properly. Our aim is to make the handover an enjoyable part of the experience, not a complicated one.
Any relevant paperwork or checks will be covered during this stage, and we’ll guide the winner through the process so they know exactly what to expect. Nothing is rushed, and arrangements are only made once everyone is comfortable with the plan.
If you have a question we haven’t covered, we’re always happy to help. Just get in touch and we’ll take it from there.
