DD1 is 10.5, small for her age and very slender. She needs a rucksack suitable for carrying all her kit to Scout camp. I've done a bit of research but am wondering if any parents of small, skinny Scouts/Guides/similar have any tips from personal experience? Am prepared to spend a bit of money, because she should get plenty of use out of it (loves camping etc so liable to carry on and do DofE etc) - but on the other hand, she's pretty rubbish at taking care of possessions, so it needs to be fairly bullet-proof!
