I was skeptical on the sizing I received (M/L), but the A-1 guard is extremely adjustable and fit snugly around my torso. I also appreciated that the soft Biofoam shoulder pads do not stick out or make your jersey protrude outward when riding. I did get a little warmer when wearing the A-1, but it wasn’t so bad that I needed to cut holes in my jersey or needed to rip my jersey off immediately after a long moto. Even though I am not the best example of, “Dress for the crash, not the ride,” I appreciate a good roost guard that offers flexibility and enough protection/roost deflection for my taste. At $119.95, the Alpinestars A-1 is a great buy with its multiple configurations and is comfortable enough for me to wear year-round.
