Size isn't everything. These mini knee pads are full of comfort and fit the knee perfectly without any added baggage. The CoolFlow® side panels provide ventilation to help reduce heat buildup. Air easily flows through the outer breathable mesh fabric and the inner perforated padding, helping you stay cool. The quick-clip buckle-style fasteners with elastic straps easily adjust to fit most sizes. To help secure these knee pads firmly in place, crisscross the elastic straps and fasten with the quick clips behind the knee.
