Product description
For tours
The Ascent 400 down sleeping bag from Rab is a high-quality all-rounder built for mountaineering and trekking. It has a mummy shape that is cut wide enough for wider shoulders and the foot box is also designed to allow a bit more freedom of movement. Plus, its spacious shape ensures comfort and excellent insulation at all times. When the temperatures drop, you can use that extra space to put on some other layers of clothes. However, despite its airiness, the Ascent 400 is super insulating thanks to the high-quality down with a 650 cuin fill power and the trapezoidal baffle design.
Construction
The trapezoidal baffles ensure that the down fill is held in place and that no cold bridges are formed. The comfortable Ascent only weighs 920 g in the standard length. Plus, you won’t need to worry about moisture thanks to the down’s hydrophobic treatment, which prevents it from absorbing moisture. As a result, you won’t need to dry out the sleeping bag all the time and you can also use it in humid environments.
You can bring it along on all sorts of tours. The inside zipped pocket, the two-way zip and the zip slider that glows in the dark are super practical whilst travelling. An amazing all-rounder: the Ascent 400 down sleeping bag from Rab!
The features at a glance:
- Lightweight down sleeping bag for trekking and summer mountain tours

I spent a lot of time researching and buying / returning sleeping bags until I found the right one. I found the rab was the right balance between quality, warmth and budget. The rab is quite roomy compared to some other bags I tried, the material feels soft and comfortable, the warmth ratio for me is great as it keeps me warm in colder months but not too hot in summer months as I can unzip it and use it as a quilt. It came in at a reasonable price too. Surprisingly I found that this compresses down quite a lot which is great for space saving in your pack. Only two downfalls for me are the feathers can escape through the pull cords and the pull cords themselves although useful for pulling tight for a snug fit can sometimes get in the way around your face etc when you are sleeping. Overall a really good bag and worth the purchase.

Great sleeping bag, super comfy and surprisingly roomy for a mummy bag. Easily fits into your rucksack and compresses into the smallest gaps for maximum space efficiency, if you don’t use the bag like I don’t. Super lightweight and there’s a handy valuables pocket too.

Hi Andy,
It's a 3/4 length zip on this bag.
My husband has got to reduce the load he carries when he cycle tours due to knee problems.. Many thanks x
Hi Susan , the packed dimensions are approx. 37 x 21 cm.
There is not RAB Ascent 400 on RAB's website, only 300 or 500. Which one is this?
Hey Matteo,
the Ascent 400 is produced exclusively for us, that is why you couldn't find it on the Rab-website.
Best,
Max
Hello Gordon, Unfortunately, no. This is a special bag that had been produced for us by Rab and had only been made available in the regular size.
