I wear a mesh Speed and Strength jacket that lets in a lot if air. The jacket, perforated gloves, helmet, jeans, and Icon shorty boots (that also let a lot of air in) in the summer.
For highway riding in summer I wear Cortech mesh pants with full armor. They're cooler than jeans on the road, and when stopped, drop off in a sec, and I can wear shorts underneath.
To each their own re: ATGATT. But if you've ever had gravel scrubbed out of road rash, or had to watch a passenger go through it because of a crash, it will make you think twice. Let us know what you purchase and how it works man!
