I've got them. They (for me anyway) took a bit to get used to. I got them because I wanted to get my boot to close and the knee/shin guards I had prevented that.
I've had them for the summer now and they get a thumbs up from me!:)
The upper straps are wide enough to wrap around my gargantuan thighs easily.
lots of padding on the side and top of the knee
Doesn't seem to "walk" around my leg much( stays put)
The lower strap seemed kinda flimsy but once the guard is tucked into your boot it doesn't really do much anyway.
I've taken multiple hits on the knees since I've had them and I can still walk!
IMHO. Moose knee pads are comfortable, not too hot and very well padded. My pants and boots keep them in place so they don't move around, with or without the strap wrapped around my leg. They seem to offer very good impact protection. I have the older design, white plastic with no holes in the plastic panels. After reading the Asterisk knee brace review I feel less than fully protected.
