My brother gave me several sets of these for Christmas immediately after his military service ended, and they are EASILY the best kneepads I have ever owned. They are relatively quick to adjust, but have a bad habit of continually sliding downwards to cover your shins if you spend a lot of time walking around in them. They`re easy to pull back up and tighten down again. After I received them I wore my sets so much that I started to feel like I had them on even when I didn`t, and that wasn`t a bad thing! I gave a few sets out as gifts, but kept a set (elbowpads too) for my own enjoyment. I used them as protection while roofing a house several months ago, and while cleaning up storm debris on a cliffside home before that in addition to regular running and gunning. These things kick ass!
