ergoPouch Cocoon Swaddle Sack 2.5 TOG – Gentle Sleep Sack for Calm Startle, Dragonflies

Introducing the ergoPouch Cocoon Swaddle Sack 2.5 TOG, a baby sleep sack that grows with your child from snug newborn swaddles to a relaxed arms-out style. Crafted for gentle breathability and comfort, it aims to create a secure, womb-like feel that can support longer, more peaceful awake-to-sleep transitions.

Adaptable design for each stage of sleep

The Cocoon Swaddle Sack starts as a snug arms-in swaddle for newborns and converts to an arms-out sleep sack with discreet shoulder snaps. When you pair it with the Butterfly Cardi (sold separately), you can explore hands-up swaddling. The bell-shaped bottom gives hips and legs room to move while maintaining a firm, cozy fit that helps minimize startle interruptions and supports a steady sleep rhythm.

• Newborn-to-arms-out versatility in one garment
• Hands-up swaddling option when used with Butterfly Cardi
• Bell-shaped bottom supports hip movement and secure comfort

Year-round warmth with four TOG options

Choose from four warmth ratings to suit nursery temperatures across seasons: 0.2 TOG for warmer rooms, 1.0 TOG for mild temps, 2.5 TOG for cooler days, and 3.5 TOG for colder nights. Selecting the right TOG can help your baby stay comfortably covered without the need for loose blankets.

• 0.2 TOG: around 71 °F / 22 °C
• 1.0 TOG: 67–75 °F / 20–24 °C
• 2.5 TOG: 59–69 °F / 16–21 °C
• 3.5 TOG: 53–65 °F / 13–19 °C

Soft, skin-friendly materials you can trust

Made with 95% GOTS-certified organic cotton and 5% elastane, the fabric remains soft and breathable through many washes. Non-toxic, water-based dyes help keep colors vibrant while staying gentle on sensitive skin. The product is approved by the Eczema Association of Australasia as a skin-friendly option for babies with irritation-prone skin.

Care is simple: a durable, durable construction means regular machine washing and tumble drying on low. A two-way zipper allows quick diaper changes, and a protective zip cover minimizes potential skin irritation during nightly changes.

Practical design features for everyday sleep

The two-way zipper provides convenient access at night, while the shoulder snaps support a smooth transition between arms-in and arms-out sleeping. The design mirrors a secure, snug fit that can help baby feel secure without restricting movement, supporting your baby’s evolving sleep patterns.
