Mosebears Sleep Sack Baby Winter Wearable Blanket — 2.5 Tog Cotton, Navy, 6-12 Months

Warmth that grows with your baby

The Mosebears Sleep Sack is designed for autumn and winter nights, wrapping little sleepers in gentle warmth without the bulk of traditional blankets. With a 2.5 tog rating, it’s suited for room temperatures below 70°F, while the recommended nursery range of 58°F to 69°F helps guide comfort during nighttime hours. The snug-but-spacious design creates a cozy air pocket around the baby, promoting consistent warmth through sleep without needing to wrap or re-adjust blankets.

Soft materials and practical design

The outer layer is 100% organic cotton, chosen for a soft, plush feel that’s gentle on delicate skin. A light polyester filling adds insulation to keep tiny bodies warm, while remaining breathable enough for comfortable air circulation. The generous sack shape allows natural kicking and movement, so baby stays comfortable without slipping uncovered.

Sleeveless for better temperature control

The sleeveless cut supports heat loss and air flow, helping to reduce overheating while keeping arms covered. This design mirrors how babies often sleep with their arms outside traditional blankets, offering warmth without restricting movement.

Smart two‑way zipper for easier nights

The zipper opens smoothly from the top for easy entry and from the bottom for diaper changes. Zipper protectors on the back and end minimize skin irritation, helping you attend to nighttime needs with less fuss.

Sizes, care, and fit

Available in S, M, L, and XL to fit growing babies, with sizes and approximate weights as follows: S 0–6 months / 10–18 lbs; M 6–12 months / 16–24 lbs; L 12–18 months / 22–28 lbs; XL 18–24 months / 26–36 lbs. For care, machine wash with like colors and tumble dry on low, making it practical for busy families.

Real-world use and outcomes

Parents report fewer nighttime adjustments as babies stay warm through longer stretches, even when the room cools. The sleeveless design and secure fit mean babies can move comfortably, while the peaceful warmth supports restful sleep for both baby and caregiver.
