Recently voted 1st in Trail magazine's Hooped Bivi test. A great alternative to a tent for the solo backpacker.

A single pre-curved 7075 T9 aluminium alloy pole provide extra headroom and ensures good ventilation making it suitable for warmer, more humid conditions. No-see-um mesh door keeps out insects and has a storm hood for better weather protection.

The GORE-TEX® FLO2 fabric creates a more comfortable sleeping environment by allowing oxygen and carbon dioxide to pass through as well as water vapour.

Please note: For maximum safety and comfort, we always recommend the bivi bag zip be left slightly open when in use.

Review: Tents? Who needs 'em? 23/08/14

Remember those days of having your poncho strapped to four trees, cowering beneath it in your bouncing bomb trying to survive the wind hitting you from all angles? Remember the joys of trying to get to your stag position and tripping over a dozen other bungees and bits of paracord hanging from other Wendy Houses strung up around you? Well wave goodbye to all that with the indulgent and some might say jack, Terra Nova Jupiter. Coming in at a hefty £250 direct from Terra Nova It’s a 1 man bivvy tent (Hence the jackness) which incorporates the latest in fabric technology to provide a complete solution to your outdoor shelter needs.

This means that the tent is made with Gore-Tex FLO sheeting which is gas permeable, or in laymen terms, it lets all your nasty body gases and expelled breath out, preventing condensation & carbon monoxide build up inside. It also includes a No-See-Um mesh door which sits behind the solid fabric door, so you can have a choice of fully sealed in, or open with the mesh up to gaze at the night stars and passing tracer whilst keeping those Mosquitoes at bay.

The hood itself can be fitted with a half moon pole support to keep the top half upright and thus creating a spacious area inside at the head with which to conduct a degree of personal admin, or to store kit without having to fumble around for it. Actually putting the poles in takes about a minute, if that. If you erect the hood you can also peg it down with the trailing lines which come off from the head. The door at the front is secured via zip, with an overhanging flap to allow water run-off and prevent seepage. Once securely pegged in with all six available peg holes, the whole structure becomes very solid and can take a serious battering from the wind.

The groundsheet is also as would be expected, waterproof and resilient to rips and tears. This was proven often enough when it was used without a roll mat or underside padding in Afghan, be it on top of stones or other miscellaneous debris, it survived intact. Terra Nova advertise it as a Waterbloc Groundsheet, which whilst it doesn’t specify if it’s actually fully waterproof, was good enough to let me lie down half in a puddle and sleep comfortably enough without any water entering in during the night. I take that to mean it is!

The storage option is a basic waterproof bag into which you can store the rolled up bivvy. With all best intentions that just became too damn fiddly, and so it ended up getting stuffed into the bergen whilst still holding the dossbag inside. This made it a job of seconds to pull it out, shake it out, climb in and zip up, giving you complete protection from the elements. So what is it actually like to sleep in? To get in you simply open the hood, sit in it, wriggle down a bit and that’s you. At 6ft my head was more or less at the start of the ‘porch’ area of the tent. Once I pulled the zip up and closed myself in partially, I had a good bit of space to play with at the front.

As mentioned, once you’re in, you can either zip the front up completely, or leave the mesh hood up and have full view to your front. With the bag zipped up you are not only warm, but the wind doesn’t manage to find an entry point regardless how much of a gale is blowing. There are two zips on the hood runner so if you decide you want some fresh air in you can adjust them to whatever angle you like, partially open them apart and not risk any seepage. The Jupiter retains heat well, often finding it more comfortable in early Jan-Feb in northern Helmand to actually sleep on top of the dossbag due to the heat inside. Again though, if you get too hot, you just open the zip a touch.

If you’ve gone for the fully erect setup you can quite comfortably eat scoff, drink a brew, read a book or even clean your weapon parts in the hood. It’s not the Tardis, but there is enough room, and considering how difficult it is on the ground to find somewhere to clean kit where the sand and dirt wont get into it, the hood soon made itself the easy answer.
If however you’ve gone for the quick and easy option of just shaking it out and climbing in it gives you that much needed insta-shelter. It’s a glorious feeling when you’ve gone into harbour for the night, the rain is chucking down and whilst the rest of them try to fasten ponchos up you just jump right in and zip up. Waking up in the morning to see everyone else drenched and you’re fresh as a daisy is priceless.

The only slight problem I had with the quick method was if you tend to toss and turn when you sleep you can wake up in pitch black and not have a clue where the zip is to get back out! The other small issue that arose from time to time was that the zip would sometimes get caught on the fabric. Not a big deal and even having to wrench it back out didn’t tear it. There is no padding in the base, so sometimes you might want to stick a mat of some sort down first, but even as is, lying in or on a dossbag made it comfortable enough. The Jupiter is pricey, exceptionally so, but it depends entirely on what you want and what your demands are. If you can get away with it on exercise, it’s ideal, but in theatre where time is precious it’s a fantastic solution and one that both myself and about another dozen lads decided to buy into. The jealousy was tangible in the rest! However, if you’re thinking about buying it for use in the UK on training or exercise, be warned, it’s not good team play to have a Jack Bivvy, check you’ll be allowed to use it first as they may want you to hold hands with someone over the Hexi TV in your Wendy House instead.

So overall, an expensively indulgent but incredibly efficient and effective shelter that is light, durable and protects you from the elements at your weakest time. With this, as has been proven countless dozens of times, you don't need a tent if that's how you want to roll.

Buy it.
Review: Almost a tent for one 28/04/14

This is a lovely piece of bivvy kit, at the luxury end (and price), but perhaps worth it. No more roughing it sleeping with bivvy material sagging on your face in this design as the simple hoop entrance creates space for gear and creates a mini tent feel, while the insect mesh means you can choose to sleep looking out at the stars with no worries about insects biting. And if it rains it's a cinch to zip up the storm flap for full protection. You've almost moved beyond bivvying with this kit; it's slightly larger and heavier than simple bivis, with a pole and pegs that take a minute or two to pitch, but it still packs smaller and lighter than a one person tent and once you've crawled in you'll feel like royalty compared to your friends slumming it in survival bags. What's more the hooped design creates space to store a bit of your gear meaning that stays dry too.
