In cleaning up around here, I found an REI Little Teton child's pack. This is for your preschool-sized kid--very small, but nice. The pack is long since discontinued, so I can't link to any stats; it's more like this that like anything I got from googling Little Teton. www.rei.com/product/102016/rei-co-op-tarn-12-pack-kids
Used it in 2004-05 when the boys were 5-7, and on the small end for their ages. More normal kids would probably wear it from about 3-5, or until they are big enough for the Deuter Fox 30 (which we moved up to in 2006).
Anyway, if you want it, it's yours for the postage. It's a little faded, because we used it in the car for a long time to corral pens and paper and stuff, but everything works and there are no holes or anything.
