From bowls to half pipes, from skate parks to backyards, Pro-Tec has spent the last 4 decades listening to the needs of skaters all over the world, in order to create the best protection available, period. The Pro-Tec Classic Skate draws its line of design right back to our original helmet model. Our 2-stage soft foam liner and the newly added EVA crown pad keep things comfortable and lightweight, making this the style of choice season after season. The Krown Action Tri-pack is designed to take abuse from all types of action sports including skateboarding, bmxing, and inline skating. Includes KROWN Knee Pads, Elbow Pads, and Wrist Guards. See below for sizing instructions on the wrist/elbow/knee pads. To ensure a good wrist guard fit, measure hand circumference at the knuckles and match to the sizes listed: M 8.0 – 9.0 inches. To ensure a good knee pad fit, measure the circumference of your extended knee and match to the sizes listed: M 13 - 16 inches. To ensure a good elbow pad fit, measure the circumference of your elbow with your arm outstretched and match to the sizes listed: M 8 - 10 inches.
