187 Fly knee pads are made of high strength ballistic nylon with double
stitching for durability. They offer super thick riveted caps and a slip on design with soft inner lining and nylon
buckle closure around calf. These are some great knee pads for $40!
Keep in mind, they run a bit small and the thick neoprene backing
stretches a bit with time. If you're unsure on the size or are on the
cusp of two, go up.
Measure the circumference around the lower thigh, about 2" from knee cap.
