A high quality, high performance, very warm and comfortable sleeping bag with minimal weight.

Rab's Ascent range of sleeping bags are duck down filled performance sleeping bags designed for regular use.

Made using durable and lightweight Pertex Microlight fabrics, they give you durable build and construction, with very effective warmth for bags of such low weight.

Their semi-rectangular shape is great for those who don't like the restriction of a mummy shaped bag, and will most likely be appreciated by those buying their first down bag.

The Rab Ascent 700 sleeping bag comes with two storage sacks: a large storage/carry sack, and a compression stuff sack. This gives you the option of compacting the bag down to conserve space in your kit, or keeping it uncompressed for long term storage, to preserve the down.

Good bag, nice price, 07 November 2015
By Stephen C (Manchester)
I've used this bag a few times now, down to just above freezing.
I would expect to be warm at those temps, and I was. My wife is a very cold sleeper and she was also toasty.

Whilst we haven't really tested the limits of the bag yet, it feels great, has lots of room and is very comfortable.

Compresses much smaller than the supplied sack allows.

Will be getting another 2 this winter.

Excellent Product, 16 June 2015
By spence (Sheffield)
Used this bag on a mountaineering trip mid January this year - My number 1 bag (RAB expedition 1200) was out of action due to a rip and I had to resort to taking this.

I was pleasantly surprised by the warmth that it gave in the freezing temperatures. Even down to -24C I was still 'warm' and had no trouble sleeping! I was a little nervous when I realised I would have to resort to this bag, however it went above and beyond the recommended.

Only 1, slight problem - Along the zip seam seems to be a slight cold spot, and seemed to lose a lot of direct heat from here, making one side of my body feel a lot colder than the other!

All in all, amazing sleeping bag that when pushed to the limit really supersedes expectations.
