The Unnivoll fleece baby sleep sack is crafted from soft, 100% microfiber polyester, delivering a gentle touch for sensitive skin. It’s designed to support a secure sleeping environment and is CPSC-certified to align with safety standards for infant sleepwear.
With a 2.0 Tog rating, this wearable blanket suits indoor rooms around 64–70°F (18–21°C). The fine exterior fleece feels plush, while the interior fleece adds light insulation, helping your baby stay comfortable without overheating.
Thoughtful details make nighttime care easier and more predictable:
Care is simple: the sleep sacks are machine washable and can be tumble dried on low. Available in four sizes—S (0-6 months), M (6-12 months), L (12-18 months), XL (18-24 months)—so you can pick a fit that matches your baby’s growth. For the best result, measure height and weight and refer to the size chart before selecting a size.
Every baby is unique, and many families notice a balance of softness, warmth, and practical design in their nightly routine. Unnivoll emphasizes comfort, safety, and ease of use in everyday babywearables, helping parents focus on what matters most during late-night feeds and peaceful sleep.
