Lightweight & Small backpack or bag for Disney

[chewbacca]

I am looking to get 2 lightweight bag or backpacks for our trip to Disney next year. I will be using them for taking and extra change of clothes/diapers for the kids and just some small items we might need. I have a Maclaren Twin Triumph stroller that I will be taking so the baskets are not huge. These will need to be ale to fit in those baskets.

I bought a Kiva backpack but it has already started ripping at the seam.

Any suggestions?

TIA!
