This is a seat muff to attach to a Miki House stroller. Free size. It has a double zipper that can be opened from either side, and the top can be removed. It has holes for the waist belt, crotch belt, and shoulder belts (three levels). The top can be secured to the stroller handle with a Velcro strap. The inside is made of colorful boa, and the outside is made of a nylon material that is windproof. You can close all the zippers to make it a muff, or you can open only the bottom to let the toes out, so I think it can be used for a long time from babies to toddlers. I think I used it for a short period of time, less than 10 times. I didn't see any stains or tears, but I would appreciate it if you could understand that it is used. #Stroller #Seat #FootCover #ColdProtection #FootMuff #ChildSeat #Windproof #Baby #SleepingBag #WarmthRetention #ColdWeatherMeasures #Warm #Blanket #Swaddling #StrollerCover #FootCover #EasyInstallation
