ergoPouch Cocoon Swaddle Sack 2.5 TOG – Baby Sleep Sack (6–12 Months, Willow)

The ergoPouch Cocoon Swaddle Sack 2.5 TOG is a versatile sleep solution designed to grow with your baby. Sized for ages 6 to 12 months, it transitions from a snug arms-in swaddle to an arms-out sleep sack, offering a secure, cozy feeling as your child develops. The design centers on calm sleep cues, a womb-like fit, and practical details that make nightly routines smoother—not promises, just possibilities for gentler evenings.

From newborn swaddle to arms-out comfort

This single sleep sack replaces loose blankets and supports a calm startle reflex with a snug, secure feel. Shoulder snaps enable an easy switch when you’re ready to loosen the hold, and for hands-up swaddling you can pair it with the Butterfly Cardi (sold separately).

Four TOG options for year-round comfort

Match warmth to your nursery and season. The Cocoon Swaddle Sack is available in 0.2 TOG, 1.0 TOG, 2.5 TOG, and 3.5 TOG to help you maintain an appropriate sleep environment without extra layers.

• 0.2 TOG for warmer rooms
• 1.0 TOG for moderate temperatures
• 2.5 TOG for cooler rooms
• 3.5 TOG for chilly nights

Note: pairing with the right TOG helps minimize the need for loose blankets, a practical approach many parents appreciate.

Soft, skin-friendly materials you can trust

Made from 95% GOTS-certified organic cotton and 5% elastane, the fabric is breathable and gentle on sensitive skin. The dyes are non-toxic and water-based, designed to stay vibrant wash after wash. ErgoPouch fabrics are approved by the Eczema Association of Australasia as a skin-friendly option.

Smart design for easy changes and movement

• Two-way zipper enables quick diaper changes with minimal disturbance
• Protective zip cover guards delicate skin from irritation
• Bell-shaped bottom provides room for hips and legs to move

Care, durability, and color

Durable enough to last through multiple babies, this sleep sack is machine washable and tumble dry friendly. Non-toxic, water-based dyes help keep Willow color vibrant after many washes.

Practical tips for use

• Start with arms-in during the earliest sleep moments, then transition to arms-out as your baby grows
• Utilize shoulder snaps and, if desired, butterfly swaddling for hands-up mode
