ergoPouch Cocoon Swaddle Sack 1.0 TOG - Sage | Newborn Swaddle to Sleep Sack (0-3 Months)

Grow-with-bab y comfort from birth to the early months

Meet the ergoPouch Cocoon Swaddle Sack 1.0 TOG in Sage, a versatile sleep solution designed for newborns from day one through the delicate early weeks. This single wearable sleepsack starts as a snug arms-in swaddle and evolves into a cozy arms-out sleep sack, offering a gentle, secure feel as your baby grows. The design supports smooth transitions between sleep modes, helping parents navigate night wakeups with less fuss and more predictability.

Custom warmth for every nursery

Choose the right TOG to match your nursery temperature across seasons. The four warmth ratings cover typical conditions: 0.2 TOG for warmer nights, 1.0 TOG for moderate temperatures, 2.5 TOG for cooler rooms, and 3.5 TOG for chilly evenings. No loose blankets means fewer sleep-risk concerns and a steadier microclimate for your little one.

• 0.2 TOG suits rooms around 71 F (22 C) or warmer
• 1.0 TOG works well at roughly 67–75 F (20–24 C)
• 2.5 TOG fits 59–69 F (16–21 C)
• 3.5 TOG is ideal for 53–65 F (13–19 C)

The sack is crafted from 95% GOTS-certified organic cotton and 5% elastane, delivering a soft, breathable touch that’s gentle on sensitive skin. It’s approved by the Eczema Association of Australasia as a skin-friendly option for babies with irritations, offering peace of mind to parents who value sensitive-skin care.

Practical design for real life

diaper changes feel easier thanks to a two-way zipper and a protective zip cover that guards delicate skin. The bell-shaped bottom gives hips and legs room to move while maintaining a snug, secure fit that helps reduce disruptive wakeups. Shoulder snaps enable simple sizing adjustments as your baby grows, and the arms-in to arms-out transition supports development without needing multiple outfits.

Durable and easy to care for, this sleep sack is machine washable and designed to withstand repeated washing and drying. Non-toxic, water-based dyes help keep colors vibrant and soft wash after wash, so the garment stays baby-friendly season after season.

Usage tips and real-world benefits

Pair this sleep sack with the Butterfly Cardi for hands-up swaddling when you choose to explore that option. Parents often notice calmer transitions from waking to sleep, a steadier body temperature, and a gentle sense of security for a baby who’s accustomed to womb-like snugness. While results will vary, many families appreciate the all-in-one design that minimizes the need for loose blankets and heavy unwraps during night-time routines.

• All-in-one swaddle to sleep sack for 0–3 month olds
• Four TOG options to fit year-round nursery temperatures
• Organic cotton blend that’s soft, breathable, and dermatologically mindful
• Two-way zipper with protective cover for quick, calm diaper changes
