ergoPouch Cocoon Swaddle Sack 1.0 TOG — 0-3 Months (Willow)

All-in-one newborn-to-sleep-sack design

The ergoPouch Cocoon Swaddle Sack 1.0 TOG is built to grow with your baby, starting as a snug arms-in swaddle for the earliest weeks and transitioning to an arms-out sleep sack with convenient shoulder snaps as milestones occur. For parents exploring hands-up swaddling, consider pairing with the Butterfly Cardi (sold separately) to broaden comfort options.

Find the right warmth for year-round nursery comfort

• 0.2 TOG: suitable for warm rooms around 22 °C (72 °F) and higher
• 1.0 TOG: ideal at about 20–24 °C (68–75 °F)
• 2.5 TOG: best when the nursery is 16–21 °C (60–70 °F)
• 3.5 TOG: for cooler evenings at roughly 13–19 °C (55–66 °F)

Organic cotton comfort for delicate skin

Crafted from 95% GOTS-certified organic cotton and 5% elastane, the fabric remains soft, breathable, and gentle on sensitive skin. The material is recognized as eczema-friendly by the Eczema Association of Australasia, offering a skin-conscious option for babies with irritations.

Practical design for nighttime care

• Two-way zipper enables quick diaper changes with a protective zip cover to shield tiny skin
• Shoulder snaps support easy transitions between arms-in and arms-out configurations

Hip-friendly fit for growing babies

The bell-shaped bottom provides room for hips and legs to move freely, while the snug, stretchy fit helps reduce startle reflex and mimics a secure, womb-like feel. This design can support longer, more restful stretches of sleep.

Durable, easy to care for

Machine washable and built to last through multiple babies. Non-toxic, water-based dyes help maintain vibrancy and softness after repeated washes, and the sack is suitable for tumble drying on low.

Real-life use cases

• Night-time routines: a consistent layer that adapts as your baby grows
• Day naps: breathable fabric helps prevent overheating during daytime sleep
• Travel or daycare: compact, warm layer without bulky blankets
