Mosebears Baby Sleep Sack with Legs - 2.5 Tog Winter Cotton Sleep Sack for Toddlers (3T-4T)

Cozy, safer sleep for toddlers

The Mosebears Baby Sleep Sack with Legs blends a soft organic cotton outer with a gentle polyester filling to replace loose blankets. Thoughtfully designed for spring, autumn, and winter, it delivers warmth without adding bulk while keeping little arms free for natural movement.

With a 2.5 tog weight, this winter-ready model is best used in rooms around 58–69°F (and commonly comfortable in ranges like 64–71°F depending on your nursery and baby’s clothing). The sleeveless cut promotes airflow and heat regulation, helping little ones stay comfortable through the night without overheating.
