ergoPouch Cocoon Swaddle Sack 1.0 TOG – Sage Baby Sleep Sack, Arms-In/Out Transition, Organic Cotton

Flexible, growing sleep solution

The ergoPouch Cocoon Swaddle Sack 1.0 TOG in Sage is a versatile sleep wearable designed to accompany your baby through early months. It starts as a snug arms-in swaddle for calm startle responses and can be converted to an arms-out sleep sack as your little one grows and becomes more mobile. When you want hands-up swaddling, you can pair it with our Butterfly Cardi (sold separately) for added versatility during the transition.

How to choose the right warmth for year‑round comfort

Safe sleep is supported by selecting the appropriate TOG for your nursery temperature. This model is 1.0 TOG, but the line includes 0.2 TOG, 2.5 TOG, and 3.5 TOG options so you can tailor warmth to the room. No loose blankets means fewer sleep-time adjustments and a steadier micro-climate for baby.

• 0.2 TOG: lightweight warmth for warmer rooms (about 71 °F / 22 °C).
• 1.0 TOG: balanced warmth for typical nurseries (67–75 °F / 20–24 °C).
• 2.5 TOG: extra warmth for cooler spaces (59–69 °F / 16–21 °C).
• 3.5 TOG: maximum warmth for chilly evenings (53–65 °F / 13–19 °C).

Soft, organic comfort your baby can feel

Crafted from 95% GOTS-certified organic cotton and 5% elastane, the fabric is soft, breathable, and gentle on delicate skin. Non-toxic, water-based dyes help keep the colors vibrant while staying comfortable after repeated washes. The product is approved by the Eczema Association of Australasia as a skin-friendly option for babies with sensitivities.

Practical design for night-time care

The two-way zipper allows quick diaper changes with a protective zipper cover to minimize irritation and protect baby’s skin. Shoulder snaps support the arms-in to arms-out transition, while the durable construction is designed to withstand daily use and washing.

Hip-friendly fit for natural movement and calmer sleep

The bell-shaped bottom offers room for hips and legs to move, while a secure, stretchy fit helps reduce startle reflex and mimic the security of the womb. These design details aim to support longer, more settled sleep experiences for both baby and caregivers.

Durable, easy care and safe by design

Built to last through multiple babies, the Cocoon Swaddle Sack is machine washable and safe to tumble dry on low. The combination of non-toxic dyes and dependable fabric keeps softness and safety intact after many cycles in the laundry.
