I wanted a high visibility vest to wear over my motorcycle jacket. Cycle gear shops carried great looking vests at high prices. I didn't think the job required $80 of artisanal reflectiveness.
I bought a size Large to wear over an armored size 42 US leather jacket. It fits perfectly. Some folks in the reviews complain the zipper opens due to wind pressure, they suggest adding a binder clip to secure it. I have had no problems.
I should wear this vest whenever I ride.
In addition to wearing All The Gear, All The Time, I'm always looking for new tips and tricks to help me keep my motorcycle upright. Lee Parks' Total Control: High Performance Street Riding Techniques is a wonderful addition to my library.
Clear illustrations, diagrams and photos paired with Parks not taking himself very seriously make for one great book.
Full of wonderful commonsense advice and examples, Hough never loses track of the one thing that always keeps my attention when riding: it is the things you can not see in time that kill you. I've learned some new things, like approaching a curb or curb-sized bump at a 45deg angle or greater provides for much greater stability. His descriptions of how a motorcycle balances, traction works and all the general physics are the clearest and simplest I've found.
It isn't a skills refresher course, but I'm glad to have read it.
