A must-see for moms on the go! We've created a "baby carrier cover" to make outings with your baby smarter and more comfortable. Made with durable and sturdy cotton canvas, and 100% cotton material that is gentle on the skin. The cover uses plastic snap buttons that eliminate the worry of metal allergies, so you can use it with peace of mind. This cover is a convenient item that can be rolled up and stored when you're not using the baby carrier. Even when your child wants to walk and gets out of the carrier, it won't dangle down from your waist, and you can carry it neatly like a waist pouch. It's also perfect for hanging on a stroller or storing at home! Reduce the burden on moms by streamlining your outings, which can be difficult with a lot of luggage, with this cover. This stylish and functional item is a great ally for busy moms. ★M size...

We use sturdy canvas fabric, so there is no lining, but it fits properly. Machine washable. We recommend using a laundry net.
