ORTLIEB
21 L COMMUTER BACKPACK
This bag is well built, waterproof and simple. Originally made for cyclist, but what’s a bicycle? but a motorcycle without the fun engine bits. I’ve tried motorcycle specific bags in the past but I haven’t found one that doesn’t leak. I normally carry a puffy jacket, vest, hat, gloves, goggles and a camera in this bag. All of these items need to be safe from the elements. This bag does that.
Tip: Always use the waist strap when riding. Nobody wants a floppy bag.
