The strap can be worn on either shoulder with ease and has a quick-adjust release so you can take it off quicker than Clark Kent can get changed in a phone booth.
Overall, I found the Halo Zero to be a comfortable, functional, and very well thought out product. Its simple design keeps it easy to carry and the LED lights stayed bright after two weeks worth of bike commuting (if the strip does go dark, you can just get two fresh CR2025 batteries.) All you need is a laptop sleeve and a bike.
