Two-Stage Sleep Sack: Arms-In to Arms-Out

Meet the ergoPouch Cocoon Swaddle Sack 0.2 TOG in Willow—a soft, breathable sleep solution built to grow with your baby. It starts as a snug arms-in swaddle for newborns and transitions to an arms-out sleep sack, supporting your baby through key sleep milestones. Shoulder snaps enable quick adjustments, and compatibility with the Butterfly Cardi (sold separately) offers hands-up swaddling for comforting, near-embrace moments.

Why parents value the cocoon style

The bell-shaped bottom provides hip and leg room while the snug fit helps minimize startle reflex, creating a secure feel that mirrors the womb. This design aims to support longer, more restful sleep without needing multiple products.

• Arms-in for newborn comfort and arms-out as your baby grows
• Shoulder snaps for simple, fast adjustments
• Optional hands-up swaddling with the Butterfly Cardi
