There are a ton of cloth diaper accessories out there, so how do you decide what you really need?  Each accessory has a very specific purpose. Some may have a very narrow focus while others don’t. However, wet bags are an accessory that falls into that category of “must-haves,” especially if you plan to use cloth diapers on the go.  What’s a wet bag? A wet bag is an easy way to store your dirty cloth diapers when you’re away from home. It is a reusable, waterproof and leak resistant bag that zips shut to help keep odors (and liquids) from escaping.
