Backpack Ice Chest Where Can I Find A Childs Mesh Backpack?

Where can I find a childs mesh backpack? - backpack ice chest

From my children's school is a mesh or clear backpack, and in the past, clear plastic simply do not have. My 11 years was a Jansport backpack, but my 4-year-old will start school in the fall and would like a backpack to find greatness. The only ones I saw in his hand Walmart knees of children in primary schools. I wish that can be adapted to find him, but it is just the icing on the cake.
