• Meet SNOO Comforter Sack: Specially designed to be used in SNOO Smart Sleeper, SNOO Comforter Sack helps 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!
• Warm, Cozy & Safe: Keeps babies warm during nippy nights and naps—without risky loose blankets! Made with a super-soft 100% organic cotton shell that’s filled with 100% recycled insulation and a Thermal Overall Grade (TOG) rating of 2.0, SNOO Comforter Sack safely adds warmth when babies need it.
• All the Features You Love: SNOO Comforter Sack still has all the other features parents love about our original award-winning baby sleep sack, such as patented wings that secure babies on their backs in SNOO; snug inner bands that keep babies tightly wrapped; and shoulder snaps that allow arms-out sleeping.
• Speedy Two-Way Side Zipper: Our handy two-way zipper makes late-night diaper changes a cinch, and it’s positioned to the side to let parents easily layer SNOO Sack over any outfit.
• More Infant Sleep: Our baby swaddle sleep sack prevents startles and boosts babies’ sleep quality with special inner flaps that give the snug embrace your little one loved in the womb. Plus, its arm openings can unsnap to allow for arms out, making it a great transitional swaddle for moving to the crib.
