-Beefy neoprene construction.
-Heat-taped rear seam for less irritation behind the knee.
-Covered hinges so the refs will let you still play.
-Removable felt "U" buttress for optional patellar support.
-Pull tabs for easy application.
-Straps made of a product that rhymes with "melcro" to cinch the brace above and below the knee. -Open patella design lets your knee say "hello" to the world.
-Adjustable hinges allow for limiting knee range of motion (ROM) -flexion/extension, if desired.
-Made by a man in Missouri, not a 7-year-old in China-land.

If your favorite pair of jeans was made out of neoprene, had bi-lateral hinges, and a removable "U" buttress for your knee-cap, AND were sold one leg at a time, this would be them. People that are hard on their braces really like this one because it's tough and just works. No fancy wizardry here.

*Sizing is the cirfumference around the middle of the knee, in inches.
