Happiest Baby SNOO Comforter Sack — 100% Organic Cotton Baby Swaddle (Ivory Wildflowers, Small)

Meet the SNOO Comforter Sack

The Happiest Baby SNOO Comforter Sack is a doctor-designed, 100% organic cotton baby swaddle created to be used with the SNOO Smart Sleeper. Developed with input from Dr. Harvey Karp, this sack blends thoughtful design with practical comfort for daily use. While results can vary by child, the design aims to provide a snug, cozy feel that many parents appreciate during busy days and quiet nights alike.

Warmth, safety, and material quality

Crafted with a super-soft 100% organic cotton shell and a recycled insulation fill, the sack offers warmth on chilly nights and naps without the bulk of loose blankets. With a Thermal Overall Grade (TOG) of 2.0, it balances warmth with breathable comfort, helping your baby stay comfortable as the room temperature changes. The sack is designed to replace loose blankets, reducing the chance of fabric bunching around tiny hands and feet.
