Letter Re: Field Gear for Kids

Dear Jim,
Our family camps quite a bit for re-enactments, so the kids are used to fairly rough conditions. They have appropriate gear for most eras from Viking to US Civil War.
However, my daughter went on her first Brownie campout this weekend. She has sleeping bag, backpack (which was a full load for her at 20 lbs), spare clothes, first aid kit, Surefire and pocket light, walkie talkies and teddy bear. She also always insists on taking a couple of bottles of water. (She selected all this stuff. I’m very proud of my 8 year old.)
It would be nice, and I’m going to research, something children can use akin to web gear for carrying canteens, first aid kits and accessories.
Small 1.5″ Web belts and US issue compass pouches come to mind, with flashlight sheaths and other small accessories. Any advice is welcomed. – Michael Z. Williamson
