My son works in construction in the hot Florida heat, filled with humidity and with the sun constantly beating down upon him. He uses these knee braces to wick the sweat and moisture from the back of his knees against his work pants. Prior to using these knee braces the back of his knees would sweat and crack and bleed. This type of moisture wicking and absorbing knee braces ensure that this doesn't happen. You get two of these at a good price of $6.99 and they wash well. I only air dry them to keep their effectiveness in tact. These seem lighter than his other pair and equally stitched well. For this price you can't go wrong. After buying one pair I did go back and buy a second pair. After seeing and feeling them I probably will be buying more. Also great for runners, cycles, or joggers.
