The One was designed with the goal to match the performance of the hard-shell kayak in all-inflatable package.   It took us over 2 years of experiments with different shapes and materials - and finally the One is here.   It has drop-stitch floor that makes the One very stiff and also allowes placing your heels lower than top of the floor - for more natural paddling position.  Side tubes are flattened with internal baffles to near-vertical shapes.  Large inflatable decks in front and the back.  Comfortable adjustable seats with thigh straps and backrest... and much more.   And yes, the One is rollable.  Please check the pictures.
