A Maternitique best-seller! Soft and snuggly, these pure, organic sleep sacks will keep baby warm and cozy through all the chilly days and nights. Made with luxuriously soft organic cotton velour, the sleep sacks feature lots of little details to surprise and delight new parents who want the best for their babies.

The zipper, for example, opens from the bottom up for easy diaper access, keeping baby's torso warm while you make the change. Plus, the interior of the sleep sack is lined with soft organic cotton jersey—so the inside is as comfy as the outside.

The organic sleep sacks are sleeveless so you can layer with either short-sleeve or long-sleeve tees depending on the temperature. Brilliant.

But the greatest thing about sleep sacks is that baby's legs and feet are free to move, wriggle about and touch each other. That type of skin-to-skin contact helps stimulate baby's neural development. Now that's what we call smart!

All the velour sleep sacks feature a natural, un-dyed body with your choice of pink, blue, green, chocolate, and natural trim.

A hint from the Maternitique Moms: get at least two of these; you'll use them daily.
