Mosebears Sleep Sack Baby Winter Wearable Blanket - 2.5 Tog, Deer Pattern, 18-24 Months

Cozy, Winter-Ready Sleep Sack for Baby

The Mosebears Sleep Sack is designed as a warm, wearable blanket that stays put through the night. A 100% organic cotton outer layer provides a soft, breathable feel, while a gentle polyester fill adds lightweight warmth. With a unisex deer pattern, this sleep sack suits chilly autumn and winter nights and offers a roomy fit that encourages natural movement without letting a blanket ride up.

Better warmth, better rest—without guesswork about blankets or loose textiles. The sleep sack surrounds your baby with a snug cocoon of air, helping to maintain a stable micro-climate around the torso and lower body while they sleep.

Warmth, Safety, and Practical Design

• 2.5 TOG warmth for room temperatures below 70°F, paired with nursery guidance around 58–69°F for comfortable sleep.
• Sleeveless construction supports air circulation and reduces overheating while keeping arms free for comfortable movement.
• Smooth 2-way zipper lets you dress baby from the top or undress for diaper changes from the bottom, with protective flaps to prevent scratches.
• The generous sack design provides room for kicking yet stays securely on the baby, reducing the chance of uncovered hands or feet during sleep.

Size Range and Care

• Available in S, M, L, and XL: 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.
• Care is simple: machine wash with like colors and tumble dry on low heat to maintain softness and shape.

Real-Life Use and Why It Works

On brisk evenings, the Sleep Sack acts as a comforting layer that you can easily put on after bath time, when a blanket might slip off. Parents report fewer wake-ups due to cold drafts, as the design provides a warm, consistent micro-environment. The sleeveless cut helps keep the baby comfortable in a range of room temps, while the two-way zipper makes midnight diaper changes smoother without fully waking your little one.
