Our baby sleep sack is accordingly designed to adopt deep touch pressure technology. The thick interior fill of our weighted wearable blanket is scent-free safe beads. When gentle pressure is evenly distributed to the body it has a profound calming effect just like a mother’s embrace, helping your baby sink into a deep restful sleep.

You can rest easy knowing your baby is safe from harsh chemicals. If your baby likes to suck on their hands through the cloth, it will stay damp for a bit but is quick-drying. Meanwhile, this sleeping swaddle is machine washable, standing up to our washing and drying tests with no visible signs of wear and tear.

3. 【Make Diaper Changes A Breeze】Our sleep sack for babies is specially designed with a two-way zipper which means you can easily access the bottom for midnight diaper changes.
