ergoPouch Cocoon Swaddle Sack 2.5 TOG – Gentle, Flexible Baby Sleep Sack (0–3 Months, Oatmeal Marle)

All-in-one newborn-to-infant sleep solution

The ergoPouch Cocoon Swaddle Sack 2.5 TOG is designed to grow with your baby through the earliest sleep stages. It starts as a snug arms-in swaddle for calmer nights and transforms into a breathable arms-out sleep sack with shoulder snaps as your baby learns to move. This single piece can simplify bedtimes while providing a secure, comforting feel.

What makes it flexible

• Arms-in swaddling transitions to arms-out sleep without changing outfits or blankets
• Shoulder snaps allow quick adjustments as your baby grows
• Two-way zipper with a protective cover makes diaper changes easier and gentler on delicate skin
• Bell-shaped bottom gives hips and legs room to move while maintaining secure fit

Seasonal warmth and TOG guidance

• TOG options include 0.2, 1.0, 2.5, and 3.5 to match nursery temperatures year round
• Precise ranges help you pick the right level of warmth for cool nights or warmer days

Skin friendly fabric and safety considerations

• 95 percent organic cotton with a touch of elastane for gentle stretch
• Non-toxic water-based dyes keep colors soft and safe over time
• Approved by the Eczema Association of Australasia as a skin-friendly choice for sensitive skin
• Durable and easy to wash; designed to hold up through multiple uses

Real world use cases include late night diaper changes without fully waking baby, quick transitions when nursery temperatures fluctuate, and comfortable car rides with a stable layer that prevents loose blankets. The combination of breathable fabric, a secure fit, and a design that mimics the womb feel may support longer, more restful sleep patterns for some babies, though experiences vary.

Care and longevity are built in. The Cocoon Swaddle Sack is machine washable and designed to hold up to repeated use while keeping softness after many washes.
