The jacket is designed to fit you, even when you are not carrying your little one. Choose a size according to what size usually fits you going solo. The panel is generous enough to accomodate baby- no need to size up. That way, you stay cozy and warm without gaps or drafts!
We recommend laying your favorite fitting jacket on a flat surface, and compare measurements for a perfect fit. For other sizing questions, please reach out to firstname.lastname@example.org
