Why parents love it

In everyday use, you may notice a soft, breathable fit that helps with temperature regulation and a bottom zipper for quick diaper changes. The generous sack allows little legs to move freely while staying tucked in, and the sleeveless design helps maintain airflow without compromising warmth.

Fabric and comfort

The sleep bag is made from two layers of ultra-soft, pre-washed cotton muslin. This fabric feels gentle against delicate skin and becomes even softer with each wash, while maintaining breathability. The sleeveless silhouette improves airflow to help your baby stay comfortable through the night.
