The Asics ZD2421 Competition 4.0 Knee Pad is a great low profile knee pad for any competitive player. To start, I love how this is truly a low profile knee pad. Not only is the pad itself thin, but there is also not the extra fabric top to bottom. The thin pad means that my mobility is high because I do not have a large pad getting in the way of my running. Plus, they come in black or white, but I always pick black because I hate to see how dirty my knee pads get.

The other great feature about these knee pads is the silicone band around the top of each knee pad. I love how Asics took into consideration the little amount of fabric at the top of each knee pad and incorporated the band to help keep the knee pads in place. This means that no matter how much diving of falling is done, the knee pad will stay in place which I love.

If you want low profile knee pads but possibly not as low profile as the Competition 4.0, I would recommend the Mizuno LR6 Knee Pads. These are a great low profile knee pad, but there is just a bit more fabric top to bottom and they are great to mold around the shape of your knee. Another option is the Under Armour Volleyball Knee Pads. These, too, are great low profile knee pads which I personally played in for the majority of my high school career and loved them!
