The Unnivoll Fleece Sleep Sack is a wearable blanket designed for toddlers aged 18-24 months. Crafted from soft, skin-friendly 100% microfiber polyester, it delivers a gentle touch against delicate skin and carries a safety certification from the Consumer Product Safety Commission (CPSC), reflecting a focus on a secure sleep environment for your child.
With a 2.0 tog rating, this sleep sack is suited for indoor temps around 64-70°F (18-21°C) in fall and winter. The outer fleece offers a plush, cozy texture, while the inner fleece traps warmth to keep your child comfortable through the night. The sleeveless cut supports free arm movement and helps prevent overheating, without sacrificing coziness.
The premium smooth two-way zipper enables diaper changes without fully waking your little one. A top zipper protector guards the chin from contact, keeping the experience gentle. The roomy cut allows for kicking and movement while keeping warmth in place.
Convenience and practicality blend in this set, with two sleepers included and a simple care routine that fits busy households.
Designed for busy families, the sleep sack is machine washable and can be tumble dried on low. It comes in four sizes—S, M, L, and XL—so you can reference height and weight against the size chart to pick the best fit. The two-pack option helps you have a clean spare ready when needed.
