The X-Set 11 is complete with a collapsible 1.3L kettle and two mugs allowing you to have a cup of tea, or coffee in the outdoors. Made from flexible food grade silicone and hard anodized aluminium bases, the collapsible X-Series is light weight, compact and durable. The wide rim and stable handles allow the kettle to be used as a 1.3L pot or a 1L kettle (safe boiling capacity) and the wide aluminium base absorbs maximum heat. All of the pieces are calibrated as measuring cups, with measurements imprinted on the inside.
