In a couple of months I'll be taking my 8 and 9 year old boys on their first "real" backpacking trip. (Something like a 3 day, 2 night, 15 mile trip.) I want it to be enjoyable for them so I wanted to make sure their base weights are under 5 lbs. They'll each carry their own sleeping bags, wet weather gear, water, etc...I did some searching around and it seems most of the kids packs are in the 2+ lb weight range so I decided to do something custom.
I reached out to Chris Zimmer at Zimmerbuilt who was awesome to work with and we eventually settled on the design you see below. The packs are 10"x6"x19", I had him do a 17" torso, we shortened his standard shoulder straps about 3", and had him move them a half inch closer together. Final weight is about 17 ounces and will probably drop another ounce after some trimming. I just got them yesterday, the quality and workmanship are fantastic! My boys and I can't wait to try them out.
