Unnivoll Baby Sleep Sack 0-6 Months | 3-Pack, 100% Cotton, 0.5 TOG

Why choose the Unnivoll Sleep Sack

Designed with safety, comfort, and busy parents in mind, the Unnivoll Baby Sleep Sack is a wearable blanket that helps create a snug, secure sleeping environment for newborns and babies. Made from premium 100% combed cotton, this sack breathes and feels soft against delicate skin. A full front-to-back 2-way zipper makes diaper changes during the night smoother, while a zipper guard helps prevent friction on the chin and neck.

• Safety first: certified to meet CPSC guidelines for a secure sleep space.
• Premium material: 100% combed cotton improves softness and air flow for comfort.
• Lightweight warmth: 0.5 TOG is ideal for warmer nursery temperatures.
• Care and durability: pre-washing reduces shrinkage and allows machine washing at low temps without distortion.

The 100% combed cotton fabric, paired with a breathable weave, delivers a softer feel and improved air movement, helping your baby stay cozy without overheating. The pre-wash treatment minimizes shrinkage, so the sleep sack maintains its shape after frequent washing.
