lulumoon Sleep Sack Muslin for Baby 3-9 Months – Cotton Wearable Blanket

Year-Round Comfort with a Double Layer

Meet the lulumoon Sleep Sack Muslin for Baby, a cotton wearable blanket designed for infants 3 to 9 months. The sleep sack features a durable double-layer Muslin: a solid exterior paired with a twig-pattern interior.

The fabric’s natural breathability helps maintain a comfortable microclimate across seasons, so you can use it for naps, lounge time, and nighttime rest without swapping layers.
