8 year old Dd has her first Brownie camp in a couple of weeks - they're staying in a dormitory, but the kit list includes a sleeping bag.
I've seen cheap ones (£9.99) but I'd rather think sustainable and get something that might be useful when she's older and might want to go proper camping, or backpacking or something.
I'm totally clueless and there seems to be such a wide range of prices and brands. I'm assuming folding up small and being reasonably warm are things to aspire to, but I'd really appreciate advice from people who actually use sleeping bags themselves!
What should I be looking for, what is good value, and likely to last well?
