A lightweight exoskeleton that gives power to your knees. Running, hiking, sitting, or anything that you do where you bend your knee. these have even helped with my buddy's sister-in-law who struggles with muscular drophy.

I'm thrilled it has no negative impact on my replaced hip or back. I feel years younger!

These are not like the hip exoskeletons, I think these are more just to assist bad knees, and help you on the on the decline from a hike.
