The word Gel, at Asics, refers to the cushioning technology that has built the reputation of its shoes: the brand has applied it to its knee pads, the essentiel volleyball protection from Asics on this page, available in six colours to match the club's outfit.
The Gel knee pad protects the knee during falls on the ground, dives, and low defensive plays. It is worn in volleyball, a sport where the knee often touches the floor. It comes in black, white, navy, blue Asics, pink, and bright green.
The colour choices allow you to match the knee pad with the club shirt and socks. Black and white are the easiest to wear, while pink and bright green stand out on the court.
Sit down with your knee bent at a gentle angle and measure with a tape measure at the spot indicated by the brand: this measurement is what you will read in the size chart. The knee pad should stay in place without slipping during movement and should not be tight behind the knee.
For comparison, Mizuno offers the VS1 knee pads, and Errea provides their Tokyo knee pads. The page McDavid features the Hex protections. The discounted Asics knee pads can be found on the special offers page for protections.
The product sheet specifies the packaging. If it is sold individually, order two to protect both knees. Most players wear one knee pad on each leg.
It cushions falls on the ground, dives, and low defensive plays, which suit a libero's game. If you dive very often, compare with the other knee pads on the protections page. Choose your size based on your knee circumference.
A cold wash, preferably by hand, preserves the padding. Lay it flat to dry, out of the sports bag. Do not use a tumble dryer.
The one that matches your club's uniform or your shoes. Black and white go with any shirt. Some clubs require a common colour.
Check the size: a knee pad that is too large will slip. Position it well centred on the kneecap before playing. If it is worn out, it's time to replace it.
