Lenny... You should check this site out: http://www.ultimatekilimanjaro.com/mountain.htm

Seems February is the warmest month of the year on Kili but still well into the negative numbers

Yeah I had a look at the temps they will drop below freezing at night and your bag is only rated to 3'c. Hope you sleep warm!

Chris as it goes I do sleep warm which is a good thing and I have a liner and a downs jacket so should be ok (fingers crossed) 

Andy would you belive it but that site is the only one I have saved in my Favorites on my work computer after reviewing alot of sites (great mind and all that  ) But I just bought this guide book http://www.amazon.co.uk/Kilimanjaro-Trekking-Africas-Highest-Mountain/dp/1905864248/ref=sr_1_1?ie=UTF8&qid=1291298907&sr=8-1

Do you want to sell me something to put my mind at rest?

RedLeader will sell you his Alpkit PD600 so he can join the synthetic craze

Question?

Would a 3 season bag and a liner make it 4 season? or would it be a better idea to get a 1-2 Season sleeping bag and put it into a 3 season bag?

[suspectmonkey]

I think a liner inside a sleeping bag maybe boosts the rating by a degree or two, but personally I've never tried it.  I get tangled up enough inside a bivvy bag, never mind a liner

At the weekend I used my Pipedream 400 inside a bivvy bag even though I was in the tent.  Definitely helped and I felt very warm all night with just my base layers on.  Perhaps that might help?  Obviously the bivvy bag is heavier than a liner, but you can also use it as your survival bag and they are handy to sit on at rest stops!

There's a sleeping bag that Tesco sell that I swear by, but I do get a bit of friendly banter here on NI-Wild.  I used two of these on Saturday night inside my bivvi bag (no tent, or tarp) and was as toasty as anything.  Quite surprising really when you see that they only have an extreme rating of +1.7°C.

For the purpose of trying to make a 3 Season into a 4 Season it might be just the ticket.

This is the Tesco Micro-lite Mummy Sleeping Bag:


"This microlite mummy sleeping bag in a graphite and lime colourway offers superior insulation with reduced weight, so it's ideal for travelling light. With a polyester lining and shell at 240 togs, it has a comfort rating of +13.2-16.3°C and an extreme rating of +1.7c°C. Features include a 2-way reversible zip and 4-way compression strap to minimise the space it requires when rolled"

It really is quite tiny when compressed and only weighs 853g.  I have used this all last winter, the summit of Carrantoohill and the Crimbo camp where I'm guessing we had a temperature of -10°C, since drydag seen -6°C on his way home at 9pm.

Anyway... Worth considering as a liner, especially when it's only £13, very well made and fully machine washable.  Mine gets washed after every trip and is still in tip top condition.

Dowser, you forgot to mention that you boost the temperature rating of your sleeping bag by around 10 degrees through the consumption of Scotch

[RedLeader]

And by having the foresight to bring a hotwater bottle, ie a small dog.

Dowser I was looking at that bag the other day aswell.

Tesco do have two on the go at the moment.  My one which is fully synthetic and a Tesco Ultra-Lite Mummy Sleeping Bag, which is a down bag.  A bit more expensive and more hassle than its worth being natural down, so make sure you don't lift the wrong one.  Both are available off-the-shelf in most of the large Tesco stores.

If it's a good liner that your looking to go with your 3 Season, I reckon give the synthetic Tesco one a go.  If it doesn't work out it's only £13.  You will definately use it on it's own in the summer months for ultra lite hiking.

240 togs!?!?!  Not sure how they are measuring, but as every 2 Togs gives about an extra 7 degrees, you're good to -798     That bag's well over-engineered!

As are most household duvets... when I read this I ditched my 13.5 Tog for a 4.5 Tog so I don't become all soft and needing ridiculous amounts of insulation to sleep outdoors.  I have a selection of sleeping bags if 'the day after tomorrow' does happen... or the Russians turn off our gas

Back to serious - not a bad bag for the dough and decent weight for 2 of them.
Dowser, I'm interested if you put one bag inside the other, or just sandwiched the other bag on top (held by the bivy)?  With a decent mat to insulate from the ground, and able to sleep on your back, this would use all the insulation in an 'unsquished' way to extend the range even further.  The bivy itself would have reduced convection and helped a bit.  I would guess though that the temp at the weekend was actually warmer than -6 due to the more stable environment under the trees, and being elevated enough to be above the 'cold sink'... Ray Jardine would say, "an ideal camp"!
