Just placing this here. Just an exercise last night but a casualty turned from uncomfortably cold to chipper and warm inside a bothy bag with 2 people for company in under 5 minutes. Several brands make them. I carry the Supalite version of these from summitgear dot co dot uk. (The Supalites are less weight than the standard model but more £ and they are warmer because they don’t have a window in them). Whether your stop is planned (aka lunch) or unplanned (aka you have suffered an injury which means you can’t continue), putting your arse on a £5 foam sit mat and getting in to one of these with a few mates will make a lot of difference.
It might well make all the difference.
P.S. unless you’re in a walking group for the Under 5’s i wouldn’t recommend the 2 person tbh. 2 normal size humans wearing winter clothing probably won’t fit inside most two person bothy bags. Get a 4.
