Daddy Diaper Bag

Thinking outside of the box, and getting my husband a nice messenger diapering supplies... And also getting it for me too. 😜 I am not a girly person so wanted something a little different than what I have been seeing. 
Requirements:
Small and compact (I don't want to be weighed down)
Compartments for organization
Comfortable to wear
Does not look like a diaper bag
Definitely not diaper bags but I'm looking at these sling messenger bags. Going to get it for hubby for xmas and fill it will baby gear! We are due in early March!
