Two basses, one back: the Classic Ultra Dual carries a pair of electric basses with flight-grade protection.
MONO's Ultra construction adds a reinforced structural chassis to the waterproof M80 shell, with separated padded compartments, dual Headlock suspension and a boot-sole base — session players and doubling bassists can finally commute with both instruments safely on their shoulders.
Born in San Francisco's design culture, MONO makes protective gear for musicians with the mindset of a technical outdoor brand: high-performance textiles, structural protection where instruments actually break, and clean, functional aesthetics. The M80 series in particular has redefined what players expect from a professional gig bag.
