Junge outerwear always comes with an extra button/snap included with the purchase. You can usually find it in the inner pocket in a small pouch. So, if you happen to lose a button/snap, you can replace it with a new one. If you've lost the extra button/snap, please don't hesitate to contact our customer service, and we will be happy to assist you. Including an extra button/snap promotes longer-lasting outerwear, which we consider sustainable.
