The Goose Bump Panel Extensions provides premium warmth and coverage during pregnancy. Reverse fits a baby carrier. This is a Size F bump panel that zips right into select Canada Goose jackets to provide space for a growing bump. Once the baby arrives, you can flip it around and wear your jacket over a baby carrier. Refer to the brand website for the correct size: https://www.canadagoose.com/us/en/pr/goose-bump-extension-panel-699363115027.html?Color=61&Size=F&gad_source=1&gbraid=0AAAAADQAs8pKg23roKOWcRLxIamcR0Vmu&gclsrc=aw.ds&pid=699363115027&src=googleshopping Excellent used condition. I wore while pregnant and briefly with my newborn, but no visible flaws. It still has tons of wear left!
