Short very comfortable, very expensive, very quickly worn

That would actually be the perfect kneepads for tours. The d30 material feels great on knees, through the zipper can be the saver sometimes quickly move out and rubs it in, there is practically nothing.
Unfortunately, 100 also a steep price.

[Update after the first longer tour]
Unfortunately, the schooner leiert extremely strong from the thigh opening. After about 4-5 hours was enough space to push through my hand to the bottom opening.
So the schooner is no longer usable. During the journey he now slipped on the knee and scrapes and is indeed well imagine that the schooner would no longer remain in place during a crash.
Also, the zipper opens unfortunately again to a few millimeters and you have to pull him regularly during the journey.

That's why I reduce the rating to one star, initial comfort is no criterion for kneepads. Fall protection and durable fit already, and this, unfortunately, not at all offers of AMX.
