Hello does this fit Edward’s and Co Oscar base and seat?

Hi Abby, this durable yet lightweight bag fits and easily covers most standard and double strollers, and features a drawstring closure with adjustable lock, reinforced seams and dual carry handles. If you are worried though, I would recommend going into your local Baby On The Move and testing one out first. Here is a list of our store locations here: https://www.babyonthemove.co.nz/store-locations/. Hope that helps
