Woolino Merino Wool & Organic Cotton Baby Sleeping Bag — 4-Season Classic Sleep Sack (18-36 Months)

Woolino Merino Wool and Organic Cotton Baby Sleeping Bag

Designed to simplify night-time comfort, this sleep sack blends breathable merino wool with a gentle organic cotton outer. The lining features 100% Australian merino wool, renowned for softness and natural temperature regulation. In real-world use, many families notice a stable sleep climate for their little one, with fewer shivers in cooler rooms and less overheating in warmer ones.

All-Season Comfort with One Sleep Sack

Thanks to merino’s inherent properties, the lining adapts to varying room conditions, helping maintain a steady microclimate next to baby’s skin. The sack is sized to grow with your child, reducing the need for multiple sacks or TOG-based layers as seasons change.

• Three standard sizes cover 0-6 months, 6-18 months, and 18-36 months for long-term use
• Year-round design replaces loose blankets and supports a consistent sleep setup

Care, Safety, and Practical Details

Intuitive design lowers bedtime hassles: a classic no-snaps silhouette with a two-way zipper for top-down and bottom-up access, flat opening for easy dressing, and zipper guards to protect delicate skin. A nursery thermometer and dressing guide are included to help you gauge room conditions and dress accordingly.

• Two-way zipper allows quick diaper changes while keeping baby covered
• Zipper guards protect the skin and discourage chewing
• Opens flat for effortless dressing and changes
