The original mei tai/SSC winter cover! Outer layer of 200 weight fleece in gun metal; lining and pocket black microfleece. The foot pocket of our winter baby carrier cover is elasticized to snug around baby's legs and keep them toasty. The top flap simply folds over the top of your mei tai or SSC and snaps over the shoulder straps. You put it on prior to putting the carrier on, so you can even use it in a back carry easily. 100% polyester, made in the USA.
