Seat Roll Premio is the world’s first on-bike storage solution powered by the Boa® Closure System.  The foundation of the Premio Seat Roll is a waxed canvas of SILCA’s own creation.  Heavyweight cotton canvas is first hot-melt waxed for water-proofing, and then computer quilted with reflective thread for improved visibility.  Seat Roll Premio attaches effortlessly to your seat rails using the beautiful Boa® Closure System allowing for a lighter weight, more durable, more powerful and more adjustable attachment to the seat rails than traditional designs.  Seat Roll Premio has 3 pockets sized to hold 2 CO2 cartridges with regulator, an inner-tube up to 700×45, and a multi-tool or other accessories.
