Diaper bags can swell to monumental proportions and unless you're packing up to track your way across the desert Bedouin-style opting for a smaller tote might be the way to go. This JJ Cole System Bag 180 ($69) is compact and practical. Strategic pockets abound so you'll be able to fetch the essentials in no time flat. There's a removable pouch that fits diapers and wipes - stash it your handbag when you want to travel even lighter. The cheery vine pattern is bright and pretty, but not so femmy that dads will think carrying it dilutes their manliness.
