DD (10) needs sleeping bag - should I buy child or adult size?

[Mummyinamask]

As title says really - DD going away for weekend and needs bag but I know nothing about such things. Is it worth buying a child size bag (she is quite tall) or is an adult folded over ok?
What about these mummy shapes?!

Any advice welcome!

Adult. The children sized ones are pretty small - I think my two grew out of them by 10.
Mummy shapes are cosy but the DC didn't really like them as they couldn't move much inside them.
Is she going to be outside? Brora!

Brrrr!

Adult definitely. Get her to try some to see which feels comfy. My DD can't sleep in a mummy one, she likes to sprawl, so has a pod type bag. Check the temperatures it is suitable for as well. A season two is just warm enough for an English summer, you need a three/ four season for spring/ autumn camping.

Is she camping in or out?
I would go for an adult one. My DS likes mummy style. I think they are warmer but more restrictive.

Wow! So many replies so fast! Thank you!

She will be indoors but is a wriggler so adult it is.

Thanks again - you have saved me hours of online shopping indecision

Adult and if it's too long tie a belt around the bottom to shorten it until it fits.

I am in my thirties and still use the sleeping bag i got when i was ten (its cotton lined and soft so is used underneath my newer bag).
