Trying to find a small cheap molle backpack for an edc load consisting of a 7" android tablet, some hot wheels cars, a water bottle and a bag of goldfish crackers. Needless to say it is not for me but my 3 1/2 year old wants a backpack like daddy's to carry his stuff in. Something around 8-10 inches tall would fit him well. Obviously this is not something I want to spend big money on but his Lightning Mcqueen and Perry The Platypus backpacks aren't tacticool enough for him now. Torso measures just over 11 inches. Any suggestions?
