What Baby wears under a Sleeping Sack

zzZipMe Sleeping Sack® Sets
Sleeping Sack + Bodysuit or Gown

Perfect for when Baby is ready to Transition from Swaddling

zzZipMe Sack® replaces loose blankets and
can’t get kicked off, so baby stays cozy all night.

Easy open elastic bottoms on our Gowns and our
handy 2-way zipper make diaper changes easy.


Transitional Swaddle Sacks are a great way to transition baby into the
zzZipMe Sack and can be worn under the zzZipMe Sack as well.


Many babies are ready for a sleeping sack around 6 months after
the Moro (startle) reflex has faded or when they are completely done
with Swaddling and sleep well in a loose fitting wearable blanket.
