I just got a pair from APS and they arrived yesterday. It's a really cool concept. They are made of neoprene, (like a knee brace) and the hiking pads velcro into sleeves on the back of the pads and then you pull them up your thigh and that's it. My main concern is weather or not they will want to slip down my legs, but after walking around the house a bit they stayed up fine. I do think they would slip if you tried to wear them over biking shorts so it's commando time! (I don't wear the tighty whities, don't like the wedgies.). For me the draw is to find something that provides the hiking support of hiking pants without the added weight, (as I struggle to stay under 200lbs.) I'm going to wear some SEA skiff pants over them and see how it works. Hopefully I'll get to try them out tomorrow and will let ya'll know.
