ergoPouch Cocoon Swaddle Sack 2.5 TOG – Gentle, Versatile Baby Sleep Sack (Daisies)

The ergoPouch Cocoon Swaddle Sack 2.5 TOG is built to grow with your baby, starting as a snug arms-in swaddle for those first, sleepy days and morphing into an arms-out sleep sack as your little one becomes more curious and mobile. This thoughtful design supports each stage of your baby’s sleep journey, offering comfort and practicality without overstating guarantees. For families exploring hands-up swaddling, you can pair it with our Butterfly Cardi (sold separately) to customize how your baby settles for sleep.

Crafted from 95% GOTS-certified organic cotton plus 5% elastane, the fabric feels soft and breathable against sensitive skin. The material is dyed with non-toxic, water-based dyes that stay gentle and vibrant through many washes. It’s even approved by the Eczema Association of Australasia as a skin-friendly option, which can be meaningful for babies with sensitivities. A two-way zipper and protective zip cover make middle-of-the-night diaper changes quicker and gentler on delicate skin, reducing interruptions during quiet hours.

Warmth you can tailor to your nursery

• 0.2 TOG for warmer rooms around 71 °F (22 °C) or higher
• 1.0 TOG for average nursery temperatures (67–75 °F / 20–24 °C)
• 2.5 TOG for cooler rooms (59–69 °F / 16–21 °C)
• 3.5 TOG for especially cool nights (53–65 °F / 13–19 °C)

Choosing the right TOG helps you maintain a comfortable microclimate without relying on loose blankets, which many parents find helpful during seasonal changes or in rooms with varying heat sources. The bell-shaped bottom provides room for hips and legs to move while the snug fit supports a secure feeling, which may contribute to longer, more restful sleep periods for many babies.

Durable, skin-friendly design you can trust

• Machine washable and designed to withstand repeated washes
• Non-toxic dyes keep colors vibrant while remaining gentle on skin
• Arms-in to arms-out conversion via shoulder snaps, growing with your baby

In everyday use, the combination of breathable fabric, thoughtful zipper placement, and a protective edge helps keep sleep routines smooth and predictable. The option to pair with accessories for different swaddling styles provides flexible comfort in your nursery, while the overall design aims to support a calm, restful start to each sleep cycle.
