Rab Men's Storm Bivi

Product Information

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 thing’s made from Pertex’s impressive Diamond Fuse fabric, a 2.5-layer ripstop nylon with specially shaped yarns that are intricately woven together to create a robust, abrasion resistant and highly durable fabric – one that’s both waterproof and highly breathable too. There are however some methods that you can use to determine a product’s quality without needing to physically have it. Another factor that can be a great indication of product quality is the brand. Brands like Rab are of course extremely well known, especially for shelters & bivis. That got us thinking though, that we’re looking at every possible item from Rab so it would be good to narrow our search down even further and only look at Rab branded products within the shelters & bivis category.

To put into perspective how waterproof this fabric is, the hydrostatic head of your average tent flysheet (basically, the amount of water it'll withstand before allowing it to pass through) is around 3000mm - the Storm Bivi's is 10000mm.

To give that price some context we then looked at all of the products available from Cotswold Outdoor in the shelters & bivis category. We found 9 items in total.

The Rab Storm Bivi is a lightweight, breathable, waterproof bivi designed to wrap around a sleeping bag, offering optimised protection from the elements.

The downside to buying online is that you can’t actually get hold of the product to try it out first. There’s so much information available online when we’re shopping now, that it’s easy to find lots of detail about products like Rab Storm Bivi. This is of course really helpful, but there’s almost too much information available, so it’s important to know exactly what you’re looking for. 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.Hyperlite Storm fabric / end zip entrance / small mesh panel vent zip rand / wide sleeping bag profile design We’re really pleased to have scored Rab Storm Bivi so highly, givimg it 8.2 out of 10, making it well above the average for all shelters & bivis.
