Kaiya Baby Unisex Sleeping Bag with Sleeves - 2.5 TOG Sleep Sack for 6-18 Months

Safe, breathable sleep for babies and toddlers

kaiya baby creates infant sleep bags with a careful balance of comfort, safety, and everyday practicality. This sleep sack blends organic cotton with a soft wool and polyester mix to stay cozy yet durable through countless washes, while preserving loft and warmth over time. The result is a wearable blanket designed to feel gentle against delicate skin and to move with your little one as they sleep.

A standout feature is the internal temperature sensing sticker placed at the chest. It gives a visual cue about the surface temperature where the baby contacts the fabric, helping caregivers adjust layers without waking the child. A double zipper and anti slip neckline ensure easy evening diaper changes and a secure, comfortable fit that prevents rough contact with the chin. The one piece with sleeves provides secure warmth while giving room for natural movement of the hips and legs.
