Order this Zip Adapter for most Canada Goose CoatsYou only need a zip adapter if the zip on your jacket doesn’t match the zip on the BellyFit. A simple test to know if the zip on your jacket will work with the BellyFit is to check if at least one of the sliders on your jacket has the markings "VISLON" and "5VS" on the back. Your jacket passed the test? The BellyFit will zip right into your jacket without an adapter.
