After freezing in my 10 year old Blacks Great Bear sleeping bag (specs are 4 season -15c, weight 2250gms, filled with Qualofill)in Langdale last weekend I need someting warmer that is not down or goose. Ok, so I know I feel the cold but perhaps my current bag is no good and over-rated. I was looking at the ME Sleepwalker III but although it is actually lighter than my Great Bear is it warmer?
I will probably use it with a thermarest (zzzz, boring I know)

I have a sleepwalker 3. Haven't use it at -15c yet, but it was too warm at zero a couple of weeks ago. Its comfort rating is -12c. Sounds about right.

Its a comfy bag. The knee thing allows you to move about during the night. I would recommend it.

Maybe you could just buy a fleece liner for your old bag though!

Fleece or Meraklon (sp?) liner could solve your probs, depends on how much warmer you need to be.

No experience of ME synth bags, sorry.

Ajungilak Kompakt Winter or Kompakt 2000 Winter.

The 2000 is £150 and has a 2 metre hydro head outer. -20 comfort

The standard is less (dunno how much) and -15 comfort. I have a friend with the 2000 and he's slept out ino the open on a night down to about -10, and was "toasty"!

there was a gorg rab bag in outside monday. bout £250 which was a 4 season. was very light too. :0)

I use a vango Q7 200 which is a suposed 3 season but i find it quite toasty enuff in the - temps

ME synth bags are toasty and the Sleepwalkers are sooooooo comfortable.
When I had the old bag and a karrimat I never slept properly, but with the Sleepwalker and a thermarest I'm a new woman.

Guy, synthetic filling technology has moved on quite a long way in ten years, and your bag will also have deteriorated with use as well, so most four-season rated synthetic bags will be warmer than your bag is now. How they'll compare with it when it was new is harder to say.

Mountain Equipment's synthetics have a good reputation, ditto RAB's. We have a Snugpak 10 on test at the moment and that seems reasonable as well. TNF's synthetic bags use a good quality fill, ditto MHW's. Ajungilak aren't bad either. In a way bags are one of the hardest items to test simply because no two people sleep at identical temperatures and nights are all subtly different in terms of conditions - temperature and humidity so up to a point you have to take manufacturers' specs on trust. If you go for something like a Mountain Equipment bag rated to the temperature you think is adequate, I'd be pretty confident it'll do the job. In relative terms, a ten-year old synthetically filled bag is about 90 in our human years...

I put in a review of my Sleepwalker III TDS in the gear section. Top Bag - the 'stretchy legs' are the dogs wotsits for me. Sometimes over warm, but toasty when the temp drops. I'd buy another, which is saying something for me...

Cheers all,

I've just bought a Dreamcather 500 and am waiting for a nice cold opportunity to try it out

Helen - you need to spend a night in a sno-hole!

I bought a ME Dreamcatcher 500 a few weeks ago and spent a long weekend in the dales when temperatures dipped to below freezing (water bottle was solid in the morning) .

The bag performed superbly , you'll love it especially the TDS system which allows free movement . I bought ME gear on the strength of many positive reviews . Top gear which I'm sure will continue with bags rated to even lower temps (Dreamcatcher 500 is rated to -5%) .
