Meet the Unnivoll Fleece Baby Sleep Sack, a wearable blanket crafted from soft 100% polyester microfleece. The fabric provides a gentle, skin-friendly touch for delicate skin, while a Consumer Product Safety Commission (CPSC) certification confirms safety-conscious design.
The 1.0 tog sleep sack is suited for indoor conditions around 68-75°F (20-24°C), making it ideal for spring and fall nights. The plush exterior and interior feel light and breathable, helping your baby stay comfortable through the night.
A premium two-way zipper allows easy diaper changes without fully undressing your toddler. A zipper guard protects the chin from scratches, keeping comfort a priority during midnight routines.
The design offers ample space for little legs to move and kick, reducing the chance of overheating while keeping the baby snug. The sleeveless cut enhances arm mobility and warmth retention in a balanced way.
This bundle includes two sleep sacks in recommended sizes from newborn to 24 months, depending on height and weight. They’re machine washable and can be dried on low heat for easy upkeep.
