The first point we need to raise for this review is that with receiving a prototype we can only write about the Ultra Mythic 180 in this current form. We would expect the final product to have slight differences in weight and design. Also, the EN temperature ratings are currently only estimates and taken using fill weight just below 180g.We had heard rumors that Rab were due to launch a new line o …

First impressions of the Hyperion are striking. The pack weight in its stuff bag of just over 600g and with its stuffed size of 15 x 20 cm is mind blowingly light and small [Regular Size]. Once out of the bag the lofting starts to take place. This is somewhat magical and once the Hyperion is fully lofted you wonder how it ever fitted into such a small space. When totally lofted it looks …

Helium 400 Sleeping Bag While the Helium 400 isn’t the warmest of sleeping bags, it comes in at a good weight of 850g for a -3 season rated sleeping bag and with a price tag of £220, it’s a fantastic choice and a great all rounder. The face fabric is incredibly soft and has a nice handle thanks to the HELIUM™ 20 outer shell and the bag lofts very well which feels great to climb in to after …

Rab have certainly made a name for themselves for offering high quality sleeping bags with a focus on warmth and weight, matched with a build quality that stands the test of time. This updated Rab Neutrino 200 we received is one of the ‘Pro’ versions. This is because the Pro version is made using a Pertex Quantum Pro outer fabric which offers better protection in damp conditions when com …

Mythic 200 Sleeping BagThe insulation value of a sleeping bag depends on three things, the amount of down, the quality of that down and the way the bag is constructed – which needs to have baffles large enough so that the down can loft freely. There are lots of other minor factors like over filling to top compared to the bottom which gets crushed, zip and shoulder baffles, hood design etc.. but th …

For a large majority of us our initial thoughts of a synthetic sleeping bag often brings with it memories of our first experiences of wild camping. Many a morning began with a battle to get this barely compressible beast back into its stuff sac, before squeezing it into an oversized rucksack only to find out it had taken up over half of the capacity. Choosing a sleeping bag is an area mo …

Choosing a sleeping bag can be a tricky affair. How each person sleeps can differ greatly so guidelines for warmth can be difficult to follow. We tend to look at the environment we are intending to use the bag then choose a rating as high as possible for the weight we’re willing to carry. Our intended use was for winter camping in the Cairngorms where temperatures often exceed minus double figures …
