The Silca Mattone Seat Pack is named after the Italian word for ‘brick’. The seat pack is an ultra-compact, water-resistant design that attaches to the underside of your saddle with a BOA Closure System. The unique zipper design allows it to access like a book, so there is no more rummaging for spares on the roadside. With a 0.61L capacity, the Mattone is ideal for any cyclist looking to carry a spare tube, lever, CO2 cartridge, a multitool, and some cash. An internal flap holds a bank or ID cards or house keys while protecting your spare tube from any sharp edges. Traditionally, seat bags have allowed their contents to jangle about, but the interior design of the Mattone holds things in place. With 15x more holding power than Velcro®, the BOA® closure system also ensures the Mattone is held high and tight under the saddle so you’ll never notice it moving about when out of the saddle and pushing up those short sharp climbs and breaking away from your fellow riders’ wheel.
