SNOO Sack and SNOO Comforter Sack (our warmer wrap), were specially designed to be used in SNOO Smart Sleeper to help babies sleep safer, longer, and happier!  And because SNOO Sack was created by world-renowned pediatrician Dr. Harvey Karp, you can trust that every detail was designed with baby safety and parent sanity in mind!

SNOO Sack 5-Second Baby Swaddle

SNOO Sleep Sack is the ultra-soft, ultra-easy swaddle sack that helps babies be happier and sleep longer—and it’s the only sleep sack that should be used with SNOO!

SNOO Sack has special wings that slip onto SNOO’s clips to secure babies on their backs and prevent risky rolling. This award-winning swaddle sack was created by Dr. Harvey Karp, America’s most celebrated pediatrician. Dr. Karp is the doctor whose 5 S’s started the Swaddle Revolution, so parents can rest easy knowing he designed every detail of SNOO Sleep Sack with baby safety—and parent sanity—in mind.

Intended for use in SNOO only.
