Anyone used it?
The Alpkit PD800 is lighter, uses higher quality down, is warmer and cheaper.
It is unfortunately however out of stock.
The RAB is a good bag though and the brand name holds its value well 2nd hand.
Rockrun have the RAB Atlas Explorer 700 on offer from £175 to £100 which uses 700g of the same 650 fill down.
For £100 it's a fantastic bag and nearly half the price of the ascent.
Yeah I think that RAB have now switched to quoting US figures on thier down products. I am tempted to get one of these. I've got a Rab Summit alpine 500 which is a great bag but a little restricted for someone my size. On Ebay you can get the Macpac escapade 500 or 700 for £72 which is a very similar bag to the rab atlas explorer semi rectangle with 80/20 600 duck down.
I bought the Rab Ascent 700 last sept/oct 2010 because I thought that a down sleeping bag would be warmer than the other one I had. I slept, or tried to, in temperatures no less than -3c and was freezing cold in this Rab Ascent 700 Bag. I wore thermals AND had a thermal sleeping bag liner as wel as others clothes eventuallyl, and also a sleeping mat. My partner, who does not feel the cold so much, said he would try it the next night, as he thought I was being a bit over dramatic. Well he, who does not feel the cold so much was very cold as well, and had all the thermal clothes and liners!
I would not recommend this sleeping bag to anyone, and when I contacted the company, they said that it depended how fit I was, how many calories I had consumed that day etc, etc, blah blah..I then bought a Mountain designs sleeping bag(in New Zealand where we were at the time), with lower spec, and it works MUCH better..no thermals, liners, etc.
Make your own mind up, but Rab saying that it is suitable for extreme temps of -31 as far as I am concerned is a joke!
Well (as is easily evidinced by sundry posts) the amount of insulation that people need to sleep comfortably simply does vary wildly.
The temperatures they give are EN ratings so a fairly standardised test rather than made up so - absent a faulty bag of course - should be reasonably reliable.
Incidentally -31 is the limit at which it'll keep you alive. You don't normally want to go near that. -12 is the comfort rating, ie when you're meant to manage to sleep OK and I think thats the limit (could be the middle of the range) so getting cold @-3 certainly isn't impossible if a cold sleeper.
hey just wondering if these comments about degrees are in celcius or farenheit? thanks
