ergoPouch Cocoon Swaddle Sack 3.5 TOG - Baby Sleep Sack for Calm Startle Reflex, Arms In/Out (Oatmeal Marle)

Meet the ergoPouch Cocoon Swaddle Sack 3.5 TOG, a versatile sleep solution designed to grow with your baby from newborn arms-in snuggles to arms-out sleep. It converts easily with shoulder snaps, supporting your baby through the sleep journey. If you want more room for hands-up comforting, you can pair it with our Butterfly Cardi (sold separately) for added swaddling options.

Grow-with-You Design and TOG Options

Available in four warmth ratings, the Cocoon Swaddle Sack helps you tailor coverage for year-round nurseries. The 3.5 TOG is ideal for cooler nights, while lighter TOGs are available for warmer months. Using a sleep sack in place of loose blankets reduces common sleep risks and helps maintain a steady microclimate for your baby.

Skin-friendly, Durable Materials

Crafted from 95% GOTS-certified organic cotton and 5% elastane, the sack is soft, breathable, and gentle on sensitive skin. Non-toxic water-based dyes keep colors vibrant after washing, and the fabric remains soft wash after wash. The product is approved by the Eczema Association of Australasia as a skin-friendly choice for babies with eczema or irritations.

Practical Design Details

• Two-way zipper with a protective cover supports quick diaper changes while protecting delicate skin.
• Bell-shaped bottom frees hips and legs, while a snug fit may help reduce startle reflex, aiming for longer, calmer sleep.
• Machine washable and built to last across multiple babies and seasons.

Usage Tips

Begin with arms-in for newborns, then transition to arms-out as baby grows. The optional use with Butterfly Cardi gives hands-up swaddling flexibility, aligning with different sleep preferences.

Choose the ErgoPouch Cocoon Swaddle Sack 3.5 TOG in Oatmeal Marle for a gentle, breathable, and versatile sleep solution that supports your baby through early sleep milestones.
