Mosebears Sleep Sack – Winter Wearable Blanket, 2-Pack, 2.5 TOG, 12-18M

Cozy, winter-ready sleep sack for babies

The Mosebears Sleep Sack is a winter-ready wearable blanket designed to keep your little one warm and comfortable through the night. The outer layer is 100% organic cotton with a soft polyester filling, offering a plush touch against delicate skin while trapping a steady layer of warmth. The gentle fabric remains breathable, helping maintain comfort during longer sleep sessions as the room cools.

Designed for autumn and winter use, this sleep sack provides a generous, sack-style fit that leaves room for kicking and movement but stays securely in place. With no loose blankets to kick off, your baby stays wrapped in warmth without added fuss during the night.

Warmth tuned for cool nurseries

The 2.5 TOG rating targets room temperatures below 70°F, with many nurseries hovering in the 58–69°F range. The sleep sack surrounds the torso with a warm pocket of air, helping to maintain even temperature without bulk. This can make night transitions smoother and give caregivers reassurance during chilly months.

Breathable, baby-friendly design

The sleeveless silhouette promotes air circulation around the arms while keeping the trunk comfortably covered. This design reduces the risk of overheating and supports natural movement, so your baby can stretch, wiggle, and drift off more calmly.

Smart zipping and protection

The smooth 2-way zipper unzips from the top for easy scooping and initial placement, and from the bottom for quick diaper changes. Zipper protectors along the back and at the end help prevent irritation or scratches during wear.
