Cozy warmth for winter nights

Meet the Unnivoll Baby Sleep Sack, a winter wearable blanket crafted for toddlers 18-24 months. Made from soft 100% cotton with a fluffy polyester fill, it offers a gentle touch against delicate skin and a snug, secure feel as your child drifts off to sleep. The 2.5 TOG rating places it in a comfortable warmth range for cool room temperatures (61℉–68℉), helping your little one stay comfortably warm without overheating during naps or overnight rest.

Safety, comfort, and freedom of movement

• Large bottom space lets little legs move naturally while remaining tucked in for warmth.
• Well-fitted neckline and sleeveless design provide flexibility and a secure feel.
• Certified to meet CPSC safety standards, giving you added confidence for daily use.

Durability and practical design

• Quilted stitching distributes the filling evenly, preventing lumping and maintaining warmth over time.
• Preshrinking process reduces shrinkage to under 2% after machine washing and low-temperature drying.
• Smooth 2-way zipper with a zipper guard protects the baby’s jaw and makes dressing or diaper changes easier without waking them.

Available in S, M, L and XL to cover a range of weights (from roughly 10 to 34 pounds across sizes), the sleep sack is designed to grow with your baby. The soft green color adds a gentle touch to nursery decor while remaining gender-neutral for everyday use.

Care and longevity are built in: wash cold, tumble dry low (below 30°C/86°F), and enjoy a practical wearable blanket that keeps its shape and feel after repeated use. This is a versatile piece for parents seeking warmth, convenience, and everyday reliability in one garment.
