The site b1glamb listed has a backpack cooler with the mesh netting top.
I purchased this item from The Christmas Tree Shop for $2.99 (their's look to be a much better quality) about 10 years ago and I have used this about 15 times every summer (beach, pool, water parks, day trips, ect) along with all my WDW trips and it is just starting to fall apart.
First of all, thanks for the web site since I was kinda thinking I will never find another one again. I have NEVER seen anyone else using one of these. And secondly, this is such a great item. It is a perfect design with just enough room designated to each compartment.
Even though I got a huge bargain the first time around I still consider the $24.95 they are asking, money well spent. This is something you will get tons of use out of.
