Sleeping Bag Ratings

Probably a 3 season I would imagine. Take all ratings with a pinch of
salt though, different manufacturers measure these things in different ways.

What would a -7C comfort and -15C sleeping bag be Season rated as?

Or is it not as simple as that!

Searched in Google and can't seem to find that kind of advice.

Cheers for that Jay.

Just had another search and sounds about right, 3 season. Not good enough
for my April trip, so try another avenue, probably hire from the holiday
company.

or a 3 season with a liner - the usually trick to add a * rating?

Where are you going in April? Anywhere exceedingly cold?

If you do find you are two cold in your sleeping bag you can always put
some clothes on, or have something to eat, like an oaty biscuit to fuel
your body and keep you warm.
Also, sleeping bag liners can add some warmth.

I don't know if this is any help Sandy.

What an amazing document Sandy. Just had a quick browse through, and very
informative on sleeping bag comfort ratings, and theory behind design. Will
read it in full later. Thanks for the link.

Yes, a 21 day treking circuit from Lukla taking in 6 peaks, finishing on
Island Peak just south of Everest.

Last trip was Bolivia and I took my Mountain Equipment bag, rated at -10C
with a silk liner. Admitted we were camping at 18000ft, and I did have to
put clothes on .... but still got cold during the night. Had an option this
time of borrowing a Skugpak, rated at -7 comfort to -15, but the
recommendation for the trip is 5 seasons, hence the original posting.
Wasn't sure on bag ratings.

For 5 seasons you really need a -20 minimum. Rab do a couple for this
rating and Mountain Equip do some too, one of theirs is rated to -40

mmm toasty.

Excellent document Sandy. Thanks for sharing.

Here's a useful quote from the paper.

"Take Extra Clothing Even in summer, it is advisable to carry
expedition weight
underwear, particularly a long sleeved thermal top and full length
leggings. A full
set weighs only 400 grams but can be used night and day. These can be
worn
under your normal clothing if it becomes cold and you can sleep in them
on cold
nights. If you are going into sub-zero conditions also take a balaclava
and bivouac
socks. It is easy to upgrade the warmth of the sleeping bag by wearing
expedition
underwear, a balaclava and socks."

Cheers

Peter (feeling warmer already...)

Decided it will be cheaper to hire one from the company I am travelling with
(KE Adventure) than buy one for a one-off trip. Getting a bit too late in
life to get maximum use out of an expensive 5 season bag.

Good call, I'd say. I used to have an ME Iceline which I bought
after a /very/ shiversome night in Glencoe in an old 3 season bag.
In 7 years I got the zip done up all the way for a whole night
once, and I eventually sold it on to a pal who's one of those folk
that can be cold at night no matter what.

Pete.
