Think before you saddle up, and strap on the Alpinestars A-Line Knee/Shin Guards. They’re specifically designed for riders pushing their limits, whether you’re a certified hotshot, or just getting into the sport. The A-Line has a tough outer polypropylene shell for protection, backed with a soft Biofoam padding for extra comfort. The reference to arguably the world’s most famous jump trail isn’t a coincidence — these are designed to keep you protected, even when your season starts getting rowdy.

Vented plastic panels promote cooling when you're pushing the pace, which is important, since hardshell pads like the A-Line can get warm pretty quickly. The adjustable hook-and-loop strapping system ensures these pads stay put, and the hard polypropylene shell shrugs off all but the very hardest of impacts. The shell is backed by Biofoam padding, helping to further reduce the chance of injury. They’re not a magic bullet, but they’ll go a long way to making sure that your next crash is a quick walk-off, not a season write-off.

The Alpinestars A-Line Knee/Shin Guards are available in two sizes, from S/M to L/XL, and in the color Black/white.

  • Polypropylene hard-shell pads
  • Soft Biofoam padding
  • Ventilated panels
  • Hook-and-loop strap

Have not used them yet...

I have pretty skinny legs and they seem to fit really well. I think they are going to work out great whenever spring comes and i can actually put them to the test.
