ergoPouch Cocoon Swaddle Sack 2.5 TOG – Baby Sleep Sack (Willow) | Newborn to Arms-Out

Versatile sleep solution that grows with your baby

The ErgoPouch Cocoon Swaddle Sack 2.5 TOG is designed as a single, adaptable sleep sack that evolves from a snug arms-in swaddle for newborns to an arms-out sleep sack as your baby grows. This clever transition keeps little bodies cozy while supporting roomier movement when needed, helping you navigate different sleep stages with one trusted companion.

Crafted for comfort and care, this sack uses soft, breathable fabric that feels gentle against delicate skin. The 95% GOTS-certified organic cotton blended with 5% elastane offers a supple stretch that moves with baby without feeling restrictive. The fabric is dyed with non-toxic, water-based dyes that maintain softness and color wash after wash, making it a durable choice for busy parents and multiple little ones.

Key features designed for ease and peace of mind

• Newborn to older babies: Converts from arms-in swaddle to arms-out sleep sack, supporting a smooth sleep journey. For hands-up swaddling, pair with the Butterfly Cardi (sold separately).
• Temperature-ready: Four TOG options help you set the right warmth for year-round nursery conditions: 0.2 TOG, 1.0 TOG, 2.5 TOG, and 3.5 TOG. No loose blankets, helping maintain a consistent microclimate.
• Skin-friendly fabric: 95% organic cotton with a touch of elastane feels breathable and cozy, approved by the Eczema Association of Australasia as a skin-friendly choice.
• Carefully designed for night-time routines: A two-way zipper with a protective zip cover allows quick diaper changes and protects delicate skin from irritation.
• Hip-friendly fit: The bell-shaped bottom provides room for hips and legs to move, while a snug, stretchy fit supports a secure sleeping posture.
• Durable and easy to wash: Machine washable and built to last, using non-toxic, water-based dyes that stay vibrant after many cycles.

Real-life use cases and everyday benefits

Imagine a midnight diaper change that’s quick and fuss-free thanks to the two-way zipper—no need to wake baby fully. The cocoon’s design remains lightweight and breathable, helping your little one stay comfortably warm without overheating. As your baby grows, the same sleep sack supports a gentle transition from snug arms-in to arms-out, offering a familiar feeling of security during sleeps that become longer and more restful.

During cooler nights, the 2.5 TOG option provides a cozy layer that doesn’t feel bulky, while the lighter TOG options are ideal for warmer rooms or daytime naps. The soft fabric and careful construction contribute to a calm sleep environment, while the option to use hands-up swaddling with the Butterfly Cardi adds a touch of versatility for families exploring different swaddling styles.
