ergoPouch Cocoon Swaddle Sack 0.2 TOG – Baby Sleep Sack for Arms-In/Out, Dragonflies

Overview

Meet the ergoPouch Cocoon Swaddle Sack 0.2 TOG, a versatile sleep companion designed for babies aged about 3–6 months. It begins as a snug arms-in swaddle to help your little one settle, then converts into an arms-out sleep sack with shoulder snaps as baby grows. For families who prefer hands-up swaddling, pair it with the Butterfly Cardi (sold separately) to tailor the fit without adding bulk.

Adaptive design for growing babies

The Cocoon Swaddle Sack blends gentle stretch with a bell-shaped bottom, giving hips and legs room to move while keeping the torso comfortably snug. A two-way zipper makes midnight diaper changes quicker, and a soft zipper guard protects delicate skin from irritation.

• Two-way zipper with protective cover
• Shoulder snaps enable easy transitions from arms-in to arms-out

Warmth options to fit your nursery

Choose from four TOG ratings to match seasonal temperatures. The 0.2 TOG is ideal for warmer rooms, while the 1.0, 2.5, and 3.5 TOGs cover cooler conditions, helping you minimize extra layers and avoid loose blankets.

• 0.2 TOG: light warmth for warm rooms
• 1.0 TOG: balanced warmth for mild climates
• 2.5 TOG: cozy warmth for cooler nights
• 3.5 TOG: extra warmth for chilly rooms

Fabric, safety, and care

Crafted from 95% GOTS-certified organic cotton and 5% elastane, the fabric is soft, breathable, and gentle on sensitive skin. Non-toxic, water-based dyes help keep colors vibrant after many washes. The material is recognized by the eczema association in Australasia as a skin-friendly option.

Fit, use cases, and sleep benefits

The bell-shaped bottom supports hip and leg movement while maintaining a secure, womb-like feel that many caregivers associate with calmer bedtimes and smoother transitions between sleep stages. This design adapts as your baby grows, offering continuous comfort through different sleep needs.

Care and durability

Designed to last through multiple babies, the Cocoon Swaddle Sack is machine washable and dries with minimal effort. The fabric stays soft and vibrant wash after wash, making it a dependable choice for busy families.
