Over the past year of testing them, I have pretty much had never taken them off while out riding, and after years use, the mesh is starting to wear a bit (getting thread bare), but the rest of the padding and the super structure are fine. Pretty amazing considering I have been wearing them 3 days a week for 2 to 4-hour rides, and they have gotten beaten up and sweated on. I have taken a few decent crashes, and they have provided adequate protection for rock gardens and technical terrain, albeit taken at moderate speeds. In addition they are great brush, bush and tree guard as you go through tight singletrack, in which it takes mini blows, and keeps the scratch level on your forearms to a minimum. They are lightweight, comfortable and only moderately warm while wearing. Most of the time I hardly notice that I am wearing them until I hit a bush while riding along.
This was a nicely made product that would suit a lot of singletrack riders to protect the elbows and forearms in technical terrain. I wish I had them when I took my digger in which I left a good deal of my flesh on that rock. I went back to the same section of rocks and bested the technical portion, and felt more confident since my elbows and forearms were protected.
I also tested their brethren Knee-Shin guard a couple of months later. They are constructed of the same material, with the waffle padding in front and the mesh in the back. The knee portion has an articulated cup of the waffle padding for coverage and has a small Velcro closure on the very top to hold it on.
The shin portion has a long waffle padded section that covers most all the shins, and then uses a mesh back with a Velcro closure. I tended to reserve the Knee-Shin guard for downhills or very technical terrain, and otherwise they were attached or in my hydration pack. The Knee-Shin guard were lightweight and moderately comfortable, but if used them for long periods of time they rubbed the back of the leg just above the knee, especially if you were pedaling a lot. The knee cup seems to kind of hold them in place, which is good, since they liked to slowly wander down your leg, and you sometimes have to give them a bit of a yank to bring them back up. Wearing Lycra tights exacerbated the issue.
I took a couple of decent crashes with them, and they helped, but somehow I always seemed to get hit right square in the spot between the top of my shoe and the bottom of the shin section?
