DC are off the cub camp soon, and I'm not sure what they should take to sleep in. They have SIMs and sleeping bags (nothing fancy), and can take thermals if the forecast looks chilly, but probably need an extra layer or two.
I thought either:
a cotton liner (knocked up from old sheets)
a fleece liner
or a fleece bag to tuck the sleeping bag into?
I have some foil survival blankets , but they would probably be a faff and get trashed!
Any advice welcome
