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.

A versatile bag

First we’ll get the disappointing stuff out of the way. This sleeping bag isn’t the cheapest, doesn’t use the highest lofting down, nor is it most compact. Because the 500 is relatively lightly filled, the down can move leaving areas where you can see through the walls of the bag. And it can leak down: we have had 3 Ascent bags, and over the more than 2 years we have had them, in total they have lost roughly a good single handful of down. So if you want a bag only for lightweight hiking and camping, you would probably chose another bag.

Now why I really like it: I bought a couple of 500s which we have used for 2 camping trips to Holland and Southern England in May and June, and also as back-ups during a six-week trip around Australasia. After uncomfortable cold experiences in years gone-by, we always use 3 and 4 season sleeping mats when camping. And because I dislike having to wash whole sleeping bags, we have always used silk liners in the bags, which are easier to wash. Under these circumstances, whenever we have used the sleeping bags, they kept us warm and comfortable. The bag is very roomy, and the down allows sleeper to perspire without getting wet and uncomfortable. And when after a hard night’s rain the tent inner was surrounded by an inch or so of water and we had to strike camp, even though parts of the sleeping bags got dipped in the water, that didn’t soak far in and dried out relatively well.

But their main use is in the cooler months during motoring trips away from home, as supplements to the bedding in hostels and B&Bs. Because of its long zip, a bag can be mostly opened out to serve as a cover or duvet. And the bags can be zipped together. So two bags can become one large bag, which can be also be used as a luxurious double thickness duvet. Or the bags can be joined along just one zip and spread out to be a double duvet.

So all in all a very versatile bag for a travelling lifestyle. I wouldn’t want to rely on a single 500 to keep me warm in close-to-zero and sub-zero temperatures, but that is what our third Ascent, a 900, is for. (And the 900 can be zipped to the 500s.)

Mixed opinion on this one....

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.

Pros:
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.

Cons:
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 ...

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.

Found a lower price online? We'll beat it by 10%
