The styling is based on a bike messenger bag and it looks like it would be a comfortable diaper bag to carry around. Dad Gear say it’s durable and comes with a host of useful stuff on the inside:

Quick Access Wipes Case
Two large interior pockets
Two bottle pockets that can be accessed from inside or outside the bag
Changing pad
Stroller straps
2″ padded shoulder strap
Removable front flap
Made from durable materials that Dad Gear say will outlast the diaper days.

The diaper bag is available in a host of different prints with something to suit just about everyone.
