How to winter bivvy on a budget

The last two years i’ve enjoyed going on campouts throughout the winter. In the UK this rarely gets too extreme (sub-zero temps are rare) but it is undoubtedly a very different undertaking for someone who has only tried a summer microadventure.

The obvious answer to this is to pony up and invest in some decent winter kit. A three or four season sleeping bag and maybe an arctic puffa jacket. The trouble is a decent down sleeping bag will set you back several hundred pounds at least. One of the things i truly love about microadventures are that they are pretty inclusive and expressly don’t require a major financial outlay. What to do then?

I have some thoughts on how to stay cozy on those cold cold nights without breaking the bank. I’ve assumed here that someone owns at least a bivvy bag, a sleeping mat and a summer sleeping bag.

Sleeping bag solutions
Ok, so a 1-2 season bag isn’t going to cut it in the winter months. How about buying (or borrowing) a second 1-2 season bag and put one inside the other? Decathlon (one of my favourite shops) do a 2 season synthetic bag for £30.

If you don’t quite want to lay out for (or have to store) another sleeping bag but need a bit ‘extra’, how about a sleeping bag liner. Silk is ideal but expensive so why not try a micro fleece for £15?

Sleeping mats
Some kind of insulating mat is a good idea even in summer months but on frozen ground it’s a good idea to double up (or is that down?). Foam roll mats are relatively cheap but if you want to maximise your ‘bang for your buck’ try something like this aluminium backed roll from Amazon for only £5.70.

Insulating yourself from the ground will make a huge difference in winter.

Hot water bottle
A few pounds will buy yourself a hot waterbottle that you can fill from a stove just before bed. It won’t last all night but it will start you off toasty. You can also get some chemical heaters that may make a useful contribution.

Pack on the layers
I’ve heard quite a few times how not wearing much to bed somehow makes you warmer. The basic laws of thermodynamics refute this i think. In a frosty situation wear many layers, even your coat if you have to. In the morning you can get up and move around to stay warm.

Get some extra socks to go over your normal socks. If you have a spare jumper or coat, put it down the bottom of your bag to keep those toes toasty.

WEAR A WOOLLY HAT, a scarf (or a buff) and some light gloves if need be. If you have a hoody pull it up. The neck and head areas lose a lot of heat otherwise.

Don’t breathe in your sleeping bag
I realise that this is a tough one but try to keep at least your mouth and nose exposed to the air. One of the enemies of warmth is being wet and breathing inside your sleeping bag may keep it damp.

You’ll need the BIG rucksack
Quite a few of the tips i’ve suggested here will add considerable bulk to your microadventure kit – 2 sleeping bags, 2 roll mats, extra clothes, a stove etc.

There is an old trope – light/small, effective, cheap – pick two. In this case i’m suggesting we go for effective and cheap.

Good luck microadventurers! If you have any of your own tips, let me know.
