Night in a bivi bag in january…….will i die?

what is a good packable sleeping back to aid my warmth.
Down is the best thing to keep you warm but is crap when wet so for winter either get a down bag with a good highly water resistant outer fabric or just stick to a synthetic bag. Synthetic bags tend to be a lot more bulky though especially with a winter rating, say -5C
Ton you’re more than likely going to have to get a Long or XL version. Most US manufacturers std length is only 6ft so you’ll need a long version e.g. TNF, Mountain Hardwear, Marmot
Even for UK makes like Mountain Equipment you’ll need the XL cos you’re a big lad.
There are loads of threads on here about sleeping bags and the relative merits of down & synthetic bags.
Golden Rule of bivvying is don’t fully zip/close it up as the condensation will make it miserable inside

For bivvying, I’d avoid down and go for something like a Mountain Hardware Lamina 0
Ton – these are great synthetic bags but you will deffo need the XL but you’ll also need to try before you buy to see if it’s wide enough at the chest. GoOutdoors in Stanningley stock the Lamina range so pop in to see if they’ve got what you needPosted 5 years agoofficialtobMember
next question was, any good pubs in Rhayader?
Haha i’m from a few miles away from Rhayader originally (Cardiff now).
The Elan pub is probably one of the nicest – I’ll be honest and admit i’m not a huge fan of Rhayader pubs in general, but I guess that’s just because I’m from there!Posted 5 years agoslugwashMember
On this year’s January equivalent to the El & Back (called Mach n Back) it was well frosty and sub zero in the night. However, some of us slept amongst the conifers where the temperature stayed nicely above zero and we weren’t coated with frost and condensation upon waking in the morning 🙂
BTW, could any late arriving riders chosing to kip down in the same vicinity as us on The El ‘n Back please keep the noise and lumens down as you stagger up from the pub in the early hours? Cheers.Posted 5 years agoChewMember
I’m still here Tony 😀
All depends on conditions and picking a good spot, as to how cold you can be and still be comfortable.

Is it better to get a good 3 season bag which you will use more and then layer up? Coat, liner, thermals, hat & socks etc.
A good mat is as important as a good bag.ton wrote:
druidh, yes mate, but i am building a ‘keep the cold at bay’ wardrobe.
got a down pullover and plenty of merino thermals to sleep in, so i figured a lighter bag would be ok.
Ah. I thought you meant you were gonna take a wardrobe with you. 😆
Remember that, if the merino gets damp while you are riding, it’ll not dry out and it will be very cold.Posted 5 years agoRusty MacSubscriber
Don’t know how the other more serious camping/bivying types rate them but I find a silk liner invaluable. My girlfriend is always sleeps cold, on our last camping weekend it got pretty frosty over night but in her 3 season bag and a silk liner she slept like a baby.Posted 5 years agoChewMember
also what is a good mat?
Look for R ratings the higher the better. You’ll loose more heat via the ground than via the air.
Love my neoair. Exped and Peak Elite also get good recomendations (but all on the higher end price wise)Posted 5 years ago
Foam mats work just as well, cheap but bulky. Many options available. Tried short mats, but after using a long mat, theres no going back for me.NickSubscriber
Are you thinking of doing El-an back? I did Mach n Back last Jan, it was great!
Best tip is to get out of the open, trees are good, even seeming impenetrable forests are more less dense once you get past the first few feet. I managed with a Alpit pipedream 400 and Filo jacket.Posted 5 years ago
just been reading a thing about camping in alaska, the guy who wrote it suggested that a foam mat with either a tin foil backing or a tin foil survival bag laid on it, was the best choice for winter.Posted 5 years ago
he said a inflatable air type mat stayed cold cos your body heat escaped through it.still s8tannormMember

Tony, some air mats contain insulation to stop heat escaping to the ground. Some of the ‘best’ are the Exped down mats (which contain down obviously), Exped also make one with a synthetic filling. NeoAir mats have a reflective barrier on the inside which doesa similar thing. Any air mat which is ‘open’ and allows air to move freely inside will be cold in winter as it offers no insulation.
A thin closed cell foam mat underneath any mat will bump up the R value by about 2.
Have a look at the mats over at AlpKit, their self inflating mats are pretty good at keeping you warm.Posted 5 years ago
