Don't underestimate the value of pockets when searching for the perfect nappy bag. This Halova Nappy Bag ($36) has over 3,600 reviews on Amazon, but it's as if the brand was listening to the needs of other parents as well. Let's start with what it can hold: a LOT. There is a large main compartment that fits a surprising amount of stuff (just watch the videos of parents piling things inside), separate storage pockets, including insulated pockets, and even a wet-clothes pocket so you can keep washcloths or dirty clothing separate. There's even a clutch side pocket that can be used to dispense napkins.
