Product Information

The downside to buying online is that you can’t actually get hold of the product to try it out first. That’s why we’ve pulled together this list of key factors for Rab Storm Bivi below, to help you choose if it’s the right product for you and your budget. layer Ripstop nylon upper / 10,000 mm hydrostatic head / 10,000/m2 breathability / width: Shoulders – 80 cm; Foot – 50 cm

There are two options for sealing the bivvy: you can either zip up the mesh panel or you can pin the mesh panel up with a toggle and zip the whole thing closed. Unlike many other bivvy bags, it doesn’t taper at the foot end, so it’s good for those who don’t like the feeling of being in a mummy bag. It also has a reinforced brow, to help keep the bivvy off your face, which makes things so much more comfortable on a wet night. According to North Face, the DryWall single skin also ‘provides unparalled single-wall breathability’. At 420g, the Assault Bivy is not the lightest, and for some it might seem just too big. But, if you’re after a top quality, waterproof bivvy bag with extra space for your boots and bag, then look no further. This new version of the Helium, released only this year, comes in 14% lighter than the previous generation, and from what we can see there’s been no downgrade in performance either.

The Hunka comes in three different colours: green, red and blue. It isn’t the lightest, but at 330g it’s still a big weight saving on any tent. It has a hood that goes nicely around the outside of your sleeping bag hood, with a simple drawstring at either side so it can be tightened around you and your bag. It has no additional venting or faffy zips and the bag tapers towards your feet. You can pair it with a tarp for added protection from the elements, if you like, but many choose not to. And that’s it. There’s not much else to say. The Hunka is a simple product with no-frills. But, on a clear summer’s night, where your aim is to feel at one with nature with your face exposed to the fresh air, then it’s absolutely the best value product on the market.

It’s no-frills, but no-frills is sometimes fine if the bag is light and protective, and that’s certainly the case here.
