What I thought

Brand new for 2018, I got a sneak preview of the Robens Crevasse II sleeping bag in Denmark last year and well and truly fell in love with it.

I have never liked restrictive mummy sleeping bags so previously always used an envelope style bag instead. The problem though is that the extra space means they are less effective at retaining heat, and really, there’s not an awful lot of choice, with most R&D going into the more popular mummy style sleeping bag.

The Robens Crevasse II is different though, although technically it is a mummy bag, it’s oversized and nowhere near as restricitve as a typical mummy bag, which was the key reason I was drawn to it. I also really liked the fabric which has a soft cotton-like feel, so along with it’s 3-season credentials, I was very keen to put it through it’s paces.

Overall Rating (4.5 / 5)

The first time I tried the sleeping bag I camped out in March. The night time temperature was hovering around the 2° mark, but I was so warm that I ended up taking off my hat and unzipping the bottom section to stick my feet out.

I’ve since spent upwards of 40 nights outdoors using this sleeping bag in overnight temperatures that have ranged from 0° to 14° and the performance of the bag is utterly brilliant.

In fact it’s a revelation not needing extra layers at night. I’m so used to wearing thermals, thick fleece pyjamas and a hat and using a second sleeping bag or duvet on top of me, that it’s taken me a while to get used to the Crevasse II.

Whilst it’s by no means a cheap sleeping bag, in my opinion if you do a lot of camping outside of the summer months, this makes a sound investment.

The quality of the sleeping bag is excellent and the extra size is a real benefit for those of us who don’t like to feel too restricted but still want to stay warm.

Whilst it’s by no means a cheap sleeping bag, in my opinion if you do a lot of camping outside of the summer months, this makes an excellent investment.

When packed this sleeping bag still takes up a fair bit of space, even when stuffed into it’s compression sack. My partner has a miniscule 3 season mummy sleeping bag which is easily 60% smaller in size when packed down, but it’s also made of a really odd shiny plastic-feeling material and is generally a far smaller and more restrictive sleeping bag. Because of the extra bulk then, the Crevasse II isn’t the type of sleeping bag you’d want to be hiking with, but for car campers, it’s perfect.

Pros

I love the colour of the sleeping bag and the cotton-like feel of the fabric
Being able to unzip the foot section is brilliant as I often sleep with my feet outside of a duvet, and for warmer weather use, this makes the bag more flexible
The warmth of this bag is amazing. Coming from someone who is almost always cold at night when camping, even with thermals, a hot water bottle and extra blankets, this is absolutely the warmest sleeping bag I’ve ever used
I love the clever flexible configuration options that allow you to use the sleeping bag more like a duvet and snuggle up by wrapping the ‘wings’ around you or pop your arms out when it’s warm

Cons

Although it does compress down and comes with a stuff-sack, It’s still pretty big – this definitely isn’t a sleeping bag for backpacking!
I’d personally prefer the side zips to go down a wee bit further to make middle of the night strips to the toilet block that bit easier

Thank you to Robens who sent us this sleeping bag to test. We were not paid to write this review.
