ergoPouch Cocoon Swaddle Sack 2.5 TOG - Baby Sleep Sack for 6-12 Months, Dragonflies

Meet the ergoPouch Cocoon Swaddle Sack 2.5 TOG, a thoughtfully designed sleep solution that grows with your baby. In one cozy piece, it starts as a snug arms-in swaddle for newborns and transitions to an arms-out sleep sack as your little one learns to roll, crawl, and settle into night time routines. The Dragonflies pattern adds a gentle touch to bedtime, making the sleep routine feel inviting rather than clinical.

Designed to balance security with freedom of movement, the bell-shaped bottom offers room for hips and legs to move, while the fit stays firm enough to help control the startle reflex. This combination can help create a familiar, womb-like feel that many families find comforting during the transition from swaddling to independent sleeping.

Temperature-Ready warmth for year-round sleep

The Cocoon Swaddle Sack is available in four TOG warmth options, so you can tailor the sleep environment to your nursery. For the 2.5 TOG version, typical room temperatures around 59–69 °F (16–21 °C) are a good reference, while other TOGs cover 0.2, 1.0, and 3.5 for different climates. Using the right TOG helps keep baby at a comfortable temperature without loose blankets.

Soft, skin-friendly fabric you can trust

Crafted from 95% GOTS certified organic cotton and 5% elastane, the swaddle sack feels soft and breathable against sensitive skin. The dyes are water-based and non-toxic, helping maintain color and softness after repeated washes. It is approved by the Eczema Association of Australasia as a skin-friendly choice for babies with eczema or irritations.

Smart details for night-time care

• Two-way zipper with a protective zip cover enables quick diaper changes and protects delicate skin.
• Bell-shaped bottom provides hip-friendly room for movement while maintaining a secure fit.
• Easy care and durability for busy households; machine washable and designed to withstand multiple washes.

Growing with your family, step by step

Starting as a newborn swaddle and evolving into an arms-out sleep sack, this piece grows with your baby. For hands-up swaddling, consider pairing with our Butterfly Cardi (sold separately) for safe, flexible positioning while you transition.

In short, the ErgoPouch Cocoon Swaddle Sack 2.5 TOG brings together warmth, softness, and practical design in a single sleep sack that fits your baby through a key growth phase. While it does not guarantee results, the thoughtful features offer a calm, secure environment that many families find helpful when night routines are in flux.
