TSG's Nose Dive pads are very similar to the excellent 661 Tomcats. The actual pad is a lightweight neoprene sleeve which features a removable hard cap that slides in place, so you can easily take it out for washing and have the option of running the pads under jeans for lightweight protection.
A large velcro strap above the knee and a smaller one below hold the pad in place, and both are wide enough to remain comfy and not dig in. Unlike the 661 Tomcats, there are also small pads to the side of the hard cap to ward off side knocks.
Overall, the Nose Dives' fit is slightly on the large side, with the sleeve extending comfortably down your leg below the pad and slightly loose where it sits above the knee - great for people with chunky thighs.
