That stuff @Sarvo is getting in sounds similar - that would be the bomb if so highly recommended.

A teaser
Will promote proper when have all sizes here
Freight only started arriving this week - thank god !!

Some good advice above.

Oftern extra clothing (rain jacket, down jacket) is better draped over your sleeping bag. If worn inside you end up compressing the the insulation and end up colder.

Also dont go to bed cold, do some star jumps or such before climbing into bed to get the blood flowing. As mentioned above hard to warm up if you go to bed cold.

Lastly what you have for dinner will make a difference to how warm you sleep. You want plenty of fats before you go to bed. Ideally something with cheese, olive oils etc. The metabolic process to digest these actually generates more heat. Avoid a dinner of simple carbs and sugar.

Why not Bivvy Bag over sleeping bag
What quality is the bag - not too good obviously

I’ve got one, it’s brilliant. They don’t seem to make the one I have, but here’s the latest version. These make a lighter sleeping bag much more versatile. I’ve actually only ever used mine Tahr hunting. :-)

I had a real cold trip once and tried heating up a rock o the primus and wrapping it in a teshirt , then using that to warm my feet etc. worked well.

Reading the title I thought this was going to be a broke back mountain type of story.....

Check out Twin Needles offer at the moment - heres the advert: "Sleeping bag rejuvenation special!!! LAST WEEKS!

That will give your existing bag a boost and that's pretty cheap compared to a new bag. Then its insulating yourself from the ground (super important), I like to use a fully enclosed bivy bag, beanie and sometimes wearing less actually helps your bag work better.

As others have said - layers. Either a second sleeping bag, a mat with a better R value or clothes you can wear in your bag. I take two puffs on cold trips (uberlight down vest and hoodded jacket) and they are sized so that I can wear the vest inside the jacket.

You also need a way of adding heat when you are cold so you don't just lie there shivering all night - hot water bottle, hand warmer, hot drinks and food. Hot food warms you in three ways (it's hot, heat is created when you digest it and then you have fuel to burn for heat). I know this as I have done a lot of fasting and it's cold and miserable in winter.

I have a lightweight synthetic bag suitable for a short bloke. Will PM.

I close my eyes and think of Rachel Riley.

Dont over do it. When youre in a down bag and you have a layer of clothes on and a down jacket etc I have found you will often times be colder than just wearing a good base layer as youre "filling the bag right up" and pushing against the outsides of it compresing the down and not allowing it to work properly, you can also end up sweating but never actually getting warm because your body is constantly trying to warm up in a damp atmosphere. I slept up in the snow the other night just my thermarest neoair venture mat (non insulated, I believe insulated mats are a have...) and macpac lattitude xp bag and wearing a base layer only and I was toasty as, bit colder when you first get into bed without wearing a down jacket but warmer and dry once you warm up the bag. I was actually using the base layer top from @Sarvo which I managed to get my greasy mitts on before the rest come into the country and it performs very well, comfy, warm, lightweight, and doesnt get smelly.

My 2c

Agree with Ryan above, don't overdo what you're wearing.

My tips
Don't go to bed cold! Even the worlds warmest sleeping bag will take an age to warm up if you're cold when you hop in it.
Wear a merino beanie until you're warm enough.
Half fill a water bladder or plastic drink bottle with hot water (hot water bottle if fly in trip) wrap it in spare hat or sock and put in your bag 5 minutes before retiring for the evening.
Keep pee bottle handy for when nature calls. Don't confuse the 2 during the night!

those cots look cool but the price is eyewatering i always get a sore hip on a pad I see there are cheap knock offs for about a hundy on ebay anyone tried one?

Ah the old synthetic Army bags. Have fond memories of sweating in it in the snow in Waiberia @ -10c.

Still have one actually. Not using it much anymore as they are f@cken heavy and bulky even in a compression bag.

Domex if memory serves me correctly.
