Mine is mesh only in the back, and see through clear plastic the rest of the way around. I like that because things don't fall out at all. I bought mine at Target maybe a year or two ago, for just a couple of bucks....it was 75% off. I have ended up using it alot.
Just as a point of clarification.....I don't necessarily fill mine full to bulging. If I think we would need jeans and sweathshirts later, they would stay in a locker or the car. I priamrily carry a backpack for the comfort, not because I have more stuff than would fit in a fanny pack.
I tend to carry just my wallet, some capri sun style drinks, some small snacks (Pringles, sweet tarts, cheese and cracker packs and so on), some tylenol (for me, I get headaches easily), a small package of hand wipes (in a ziplock bag) and my wallet.
If it's night, or we won't be going back to the hotel, I also carry those flashing light things (the kind you buy with characters on them), for my two youngest to play with.
I try to make everyone carry their own water bottle. For one reason, they 're heavy! Another is that I believe the kids will drink more if they carry their own.
