A brilliant idea for all-season, all-weather riders: the bike bags in the ORTLIEB High Visibility Line make it easier for other people to see you while you're out there on the streets. This is because all High Visibility bags not only come with reflectors, but are themselves one big reflector. The waterproof bags are made with a polyurethanecoated Cordura fabric that is woven through with a high-luminosity reflective yarn in neon yellow and black. That gives ORTLIEB High Visibility bags an added safety feature in twilight conditions and in the dark of night.
