ergoPouch Cocoon Swaddle Sack 2.5 TOG – Arms-In/Out Baby Sleep Sack, Organic Cotton, Willow

Meet the ergoPouch Cocoon Swaddle Sack 2.5 TOG, a versatile sleep sibling that grows with your baby from early days to the 3–6 month stage. This one-piece design blends a snug arms-in swaddle with an arms-out sleep sack, offering a calm, secure feel while you navigate your baby’s evolving sleep preferences. When you’re aiming for hands-up comfort, you can pair it with the Butterfly Cardi (sold separately) for added flexibility during swaddling transitions.

Four warm options for year-round comfort: The Cocoon Swaddle Sack comes in four TOG ratings so you can tailor warmth to your nursery. Use 0.2 TOG in warmer rooms, 1.0 TOG for mild nights, 2.5 TOG for cooler evenings, and 3.5 TOG when rooms dip cooler. Each TOG helps your baby stay at a comfortable, steady temperature without loose blankets, reducing night-time fuss and helping your baby settle more easily.

Skin-loving fabric you can feel

The sack is crafted from 95% GOTS-certified organic cotton and 5% elastane, delivering breathability, softness, and gentle stretch. The fabric earns recognition from the Eczema Association of Australasia as a skin-friendly choice, making it a thoughtful option for sensitive skin or irritation-prone days.

Diaper changes made simple

A two-way zipper runs the length of the sack for easy, mid-night diaper changes, while a protective zipper cover guards delicate skin from irritation or scratches. This thoughtful detail helps you navigate changes with less disruption for both of you.

Hip-safe design for growing babies

The bell-shaped bottom provides room for hips and legs to move, while the stretchy, secure fit helps reduce startle reflex and mimics the womb’s snug feel. The result can feel calmer for some babies and may support longer, more restful periods of sleep.

Durable, easy-care construction

Built to last, this sleep sack is machine washable and suitable for tumble dry on low. Non-toxic, water-based dyes ensure color and softness hold up through multiple washes, making it a dependable part of your baby’s wardrobe.

Practical, everyday versatility

Use as a newborn swaddle and gradually transition to arms-out sleeping as your baby grows. If you’re exploring hands-up swaddling, the Butterfly Cardi can be used for that option (sold separately). This sleep sack is designed to fit into real nightly routines, naps, and travel moments alike.
