Thirsties Fab Doublers

Thirsties Fab Doublers Boys


Thirsties Fab Doublers provide additional absorption and leak protection without the excess bulk. Four layers of luxuriously soft cotton velour make Fab Doublers ideal for heavy wetters and nighttime use. Available in two sizes for custom fit.

To use the doubler with a Fab fitted diaper, you can stuff the insert in the sleeve of the fitted diaper or place the doubler in a Thirsties diaper cover or Duo Wrap and secure over the Fab fitted.

For use with the one-size pocket diaper simply put the doubler in the sleeve behind the one size pocket insert.
