Blueberry Simplex 2.0 Side-Snapping All In One Diaper

The Blueberry Simplex 2.0 All In One is a uniquely designed diaper that offers optimal fit and absorbency. This all-in-one diaper comes in 2 sizes, each with 4 leg/waist settings, to allow for a perfect fit with minimal bulk.

Blueberry Simplex 2.0 Side Snapping Diaper FeaturesThe interior of the Simplex 2.0 is similar to that of the Blueberry Simplex One Size AIO Diaper and features the same birdseye cotton inner fabric, as well as the semi-attached soaker design. The semi-attched soaker also allows for the diaper to wash and dry much easier than other all-in-one diapers on the market. There is a pocket tunnel so you can easily add absorbency for naps, nights, and heavy wetters. The attached waterproof polyester outer allows the diaper to go easy on and easy off, just like a disposable.

  • 2 sizes with adjustable legs and waist for a perfect fit
  • 11 layers of 100% birdseye cotton absorbency
  • Dual-ended pocket to easily adjust absorbency
  • Waterproof outer
  • Available in fashionable prints

How to Care for Your Blueberry Simplex 2.0 AIO

Prep Instructions: Wash and dry at least once before use. Diapers with brown stretchy tabs are recommended to be washed separately in cold or with similar color diapers prior to use.

Washing Instrucions: Store dirty diapers in a dry pail or wet bag until you are ready to wash. Rinse in cool or warm water, then wash on warm or hot (not to exceed 140 degrees)with detergent. Follow with an additional rinse. Tumble dry with warm heat or hang to dry. No bleach or fabric softeners. Avoid diaper creams which may not wash out. It is recommended not to stretch or over-handle the diapers if they are warm from the dryer to help prolong wear.

The large Simplex are our favorite diapers once our babies get to the point of being fully unsnapped on the rise of the OS Simplex. They aren’t quite as absorbent as the OS but we still never get leaks and we love the side snaps! They also fit our LOs before the weight it says and fit for a long time (obviously until potty training). Everyone should give these a try!

Fantastic Diapers

I LOVE these diapers. My 21 month old fits into the Large diapers on the smallest waist setting, and they are so trim. But they hold plenty of pee. These are my go-to diapers for outings, naps and overnight.

Better than organic version. Not so absorbent as OS but still they are ok for day time. I love them more than OS because they are super thin.

I always reach for these first. It's impossible to get a bad fit. Ive been using the same size for months now and still have plenty of use left. I notice no difference between these and the organic.

Nice and trim but does wick
Reviewed by:  from Little Rock. on 8/25/2017
I love how trim these diapers are and once you learn how to snap them they are really easy to put on. They wifk at the sides when full but you can add a booster or put stay dry material between tabs and problem solved.
