Wave rolltop backpack
Go anywhere, look good doing it
Meet the WAVE Roll-Top. Built for unexpected rain, rooftop jam sessions, and long airport security lines. It expands when needed, stays sleek when not, and protects your laptop and gear like a quiet bodyguard in matte black.
Born from rhythm, made for motion
