Dabbawalla BackpacksProduct Rating: Product Review (submitted on January 4, 2011):
We have bought a few of these over the years as gifts for friends, and we have the penguin one for our 2.5 year old. They are perfect toddler bags - they are virtually indestructible, they are easy to wash, and they adjust easily. Whenever we've given them as gifts, we always hear back that they are a huge hit.
Our 2.5 year old uses his bag all the time - he fills it it with toys, and off he goes. We haven't had a chance to use the cold-pack feature, but I think we will this summer.
