Chris thanks for the question - they are 20oz boxes - but do make sure you watch part 3 because the bag broke! (the strap stitching came apart, and without the bag being overloaded and only after about a week). So i returned it and in fact wouldn't recommend for that reason. I now use the seilblot shoulder bag instead - featured in part 3 of these review videos). Best of luck. Simon
what's the oz size of the meal prep boxes?
