The XL Bowl features the same cut resistant base as the X-Bowl, but it is 77% larger. The XL-Bowl is constructed from a flexible, food grade, silicone upper that is securely bonded to a rigid, cut resistant base made of high temperature, food grade Nylon. Collapsible and unbreakable, the Sea to Summit X-Bowl folds flat for packing and brings versatility to cooking on the hiking trail. It's not just a bowl though. This silicon kitchen essential has measurement increments on the inside, a base that doubles as a chopping board when collapsed and flexible sides to create an easy pouring spout.
