I use this every evening on our porch and it fits the wagon interior perfectly, no gaps for bugs to sneak through. The padded corners are a nice touch since my toddlers are constantly climbing in and out, and it folds into the storage bag without any fuss.
Took this camping last weekend and not a single bug got to my kids while they napped in the wagon. The padded corners are a nice touch, no scratching against the frame when I pull it on and off. Folds into the little bag way easier than I expected too.
The mesh fits the whole wagon interior so no gaps for bugs to sneak through. It folds into the little storage bag and I just toss it in the diaper bag. The padded corners have held up fine after a few camping trips.
