Like everything we do, our product materials are selected with safety, functionality, and durability in mind. Our stroller frame is built with anodized aluminum to support a smooth and secure ride. Our handlebar features a leatherette grip and contains no animal by-products (which is true of all Mockingbird products). Our seat and basket are made of heavy-duty nylon, perfect for easy cleanup of any mess (and yes, there will be cleanups!).
