Organic Cotton Sleep Bag

Mushie's Organic Cotton Sleep Bag is the organic cotton baby sleep sack we recommend for parents who want a simple, safe alternative to loose blankets in the crib.

Made from 100% organic cotton muslin, this wearable blanket is lightweight and breathable, exactly what you want for keeping a little one comfortable from nap to bedtime without overheating.

The sleeveless design gives full body coverage while keeping arms free and natural. The two-way zipper makes diaper changes in the dark genuinely manageable without fully waking a sleeping baby. And full-length coverage keeps legs free from crib slats, one of those small details that matters a lot at 3am.

As a blanket alternative for crib use, this muslin baby sleep bag checks the boxes parents are actually looking for. No loose fabric, no tangle risk, and a design that supports restful, safer sleep. It's the kind of infant sleepwear that lets you put baby down and actually breathe.

At Heyday, we curate products we'd use ourselves, and Mushie's take on the lightweight baby wearable blanket earns its place for being unfussy, well-made, and genuinely parent-friendly.
