Best darn knee pads I've ever owned. Id be on my knees an hour or two at work and they were aching and throbbing in the evening until I'd fall asleep. I've still got ~40 years of work before retirement and I plan on staying healthy.
With these knee pads the evening aches go away. They have the comfiest cushions I've ever had to use. It has a 2 point strap so the back of your knee caps aren't sore from keeping it tight on your legs. It has rivets in them so you can bend your legs with ease. The only down side is it gets sweaty after long hours and hot weather, but it's like that with all knee pads.
I highly, strongly recommend in INVESTING in these knee pads to save your knees from wear-n-tear from work.
