The Mono M80 Electric Bass Guitar Sleeve sits squarely in the intersection between lightweight comfort and rugged resilience to offer a gig bag that's designed to protect like a hardshell case. Crafted with a lightweight EVA insole, weather-resistant sharkskin exterior, and roomy internal pocket for holding everything from extra patch cables to a laptop for onstage MIDI control, the M80 Bass sleeve is more like a personal four-string bodyguard than a gig bag.
