The OEX Salamanda Bivi Bag is a versatile piece of camping gear, but it truly shines in the hands of certain types of outdoor enthusiasts. The Ionosphere comes in two main parts – a double-hooped ‘undercarriage’ mesh section which forms the frame of the bivvy, and then a highly waterproof (5000mm HH) and breathable ripstop outer fly sheet which goes over the top. Both require pegging down using aluminum tent pegs which come with the Ionosphere. The fly sheet also has guy ropes to peg down to secure it. I have had it set up in severe gale conditions, and because of the low profile, there was absolutely no chance of it working loose and flying off. In Use One thing to note is that if you are over 6ft tall (I’m 6ft3 or 195cm) then you may be stretched for sleeping space inside – the sleeping area is 213cm long but this includes a sloping roof. Something to bear in mind. Hyperlite Storm fabric / end zip entrance / small mesh panel vent zip rand / wide sleeping bag profile design There are two U-Shaped openings on the top surface of the Sierra Bivy. The largest is for getting in and out and has dual zips to accomplish this task. Because it can open so wide, getting in actually pretty easy for a bivy. The second opening is on the top surface and forms a little window with a fly mesh and cover. this allows you to lie out and look at the night sky before zipping up for the night. Nice.
Which bivvy bag should I buy? [UPDATE: this is a very geeky, very helpful table to help you choose what’s best for you.] Budget What you really get with the Geertop is flexibility. It can be set up simply as a standalone netted structure to sit in if the midges are getting at you or the additional outer waterproof camo fly can be added to keep the rain off. This made it into our Outdoor 100 for 2022, with our Test Team all impressed by its superb fabric and lightweight qualities. Hi! I’mm Alastair, an adventurer and author. I invented the phrase #Microadventure and I’mve been shouting about it for a few years. You can follow the microadventures people are doing on social media here or say hello to me here.The hydrostatic head of the Helium is 20000 mm which is exceedingly waterproof and the Pertex material is also supposedly resistant to rips – however I didn’t wish to test this claim out! If you want to spend more money, then Outdoor Research also do a full Gore-Tex bivvy called the Alpine, but this is actually heavier. Some one-man tents are now so small and light, it’s hard to imagine that it’s even possible to take a more minimalist approach. But it is: enter the bivvy bag. What is a bivvy bag? It’s certainly a distinctive product due to the high, clam-shaped opening at its head, which utilises a single arcing pole to create a high (for a bivvy bag) ceiling. This makes for easy entry and exit and gives the user plenty of head space – after all, no one wants a claustrophobic bivvying experience.
The Helium bivvy itself uses a flexible fibre glass pole to form a hoop shape above your head with a zippable hood which can be pulled down over the hoop to fully zip up the enclosure if required. In good weather, the hood can be withdrawn and toggled up on the hoop, leaving a net mesh to keep bugs out. Getting in and out is ‘interesting’ as is the case with all bivvy bags. Our technique is to get it all set up with the head section fully unzipped, then undo our boots and literally step out of the boots one at a time onto the top end of the bivvy. It’s then a simple matter of sitting down and sliding in.
We recently reviewed the OEX Bush Pro Bivvi and feel we have to include it in this roundup of the best bivvy bag choices. It represents fantastic value for money, and pushes the Highlander Hawk really close for the top spot if you’re looking to spend less. In our view, the hood system is slightly better in the Highlander Hawk, but with the OEX Bush Pro being substantially cheaper, it’s certainly a close run decision. We are massive fans of Snugpak gear – they are leaders in well thought-out, rugged outdoor gear. The Snugpak Ionosphere bivy tent is no exception and straddles the line between bivvy bag and compact 1-person tent really well. There’s no wonder it’s often used by the US military – not bad for a company from Yorkshire in the UK! However, in an emergency situation, especially one that is wet and windy, a bivvy bag (or basic survival bag) can offer enough protection to save your life. For this reason, it is advisable that all trail runners carry a survival bag when running in high or remote areas – even if you’re not expecting to be out for long. Is a bivvy bag worth it? Bivvy bags are great for keeping the wind off and giving your bag a bit of extra warmth but I wouldn't use one in the rain unless I could keep the outer reasonably dry somehow. The price/weight of the more waterproof/breathable-ish bags make them not worth it to me as well as I'm more likely to use it in the dry so a waterproof one would inconvenience me 90% of the time and maybe make the difference between being wet and being soaked on the rare occasions it has rain use. But if you’re racing, then pace tends to take precedence. In a short race (only one or two nights), it’s easier to rough it and sacrifice a good night's sleep in favour of better running performance. But for long, expedition style races or Fastest Known Time (FKT) attempts, the situation is more complex, with the aim of the game being to maximise performance over a prolonged period and changing circumstances. In this situation, you'll need to consider the following: will you be able to cope with prolonged sleep deprivation? Will you be able to dry out your kit? What is the terrain on the course ? What is the climate and season?
Fancy it? If you do, then you’re in the right place. We’ve done the hard work for you, putting several products – ranging in design, style, size and price – through their paces on wild camping trips to Scotland, the Brecon Beacons and the Lake District. So, whether you’re looking to venture into bivvying for the first time or if you’re a seasoned pro at sleeping under the stars, there’s something for everyone here.
