A Peak Oyl Lite Sleeping Pad (reduced on Blacks site by rather a lot) and some feet to fit under a gas canister to stabilise my stove.
I like using a small screw on cooker, so the feet should make everything a bit more stable, and this weekend's adventure has persuaded me that my Vango 3/4 sleeping mat is a bit fiddly for use in colder conditions as you have to arrange other luggage under your legs and feet to keep them off the ground.
