A duck down filled performance sleeping bag that's warm, light and tough.

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 much more comfortable for general purpose use than a minimal mummy-shaped bag, and will most likely be appreciated by those buying their first down bag.

Mixed opinion on this one...., 31 December 2016
By Dan
I'm a warm sleeper and found this perfectly adequate (even a bit too warm on one night) for a few nights wild camping in Dartmoor and then Lake District in September and October 2016.
I'm 6Ft1 with a 43" chest and it fitted just about right.
My GF tried it and felt a bit chilly so we swapped and I had this and she used my Mountain Equipment Lamina 20 (which is warmer) in temps that were around 8°C at night.
She sleeps quite cold however so I won't take it out on the sleeping bag.

Packs up reasonably small, zip is free flowing (doesn't stick.) and easy opening from the inside.
Paid under £150 after GO priced matched and discounted.
Wider at the shoulder than some others I tried.
Soft comfortable inside material.

Sheds A LOT of feathers and down (don't wear a fleece inside as you will come out in the morning looking like a goose or duck.)
The down can settle in places so the insulation can appears thin in areas (hold the fully unzipped bag up against the light and you will see where it has settled.)

If you don't mind extra bulk and not concerned about a bit of extra weight, there are warmer synthetic bags out there that are much cheaper.
For instance my Lamina 20 was £72 and isn't that much heavier/bulkier.

Best to use a sleeping bag liner to keep the bag clean. It'll keep you a tad warmer and will prevent you from being covered in down.

Sad ..., 14 June 2016
By maggie (Highland)
Bought this 2/3 bag as its meant to be ok above freezing. Used it in June and was definitely cold, not just a wee bit - but COLD. Wish I hadn't bought it. I suggest that unless you know you will use it in HOT places don't believe the 2/3 rating - its a 1/2.
