The Fox Launch Enduro series was designed for all mountain or enduro type riding where protection is the number one priority but range of motion, comfort and flexibility have to be considered as well. The Launch Enduro series offers lightweight protection but still allows you to pedal to the top of the next stage or across a flat section of trail without the need to stop and remove your pads.
I picked up both the knee and elbow guards, and I have a month in and 1 enduro race. Exactly what I wanted, insurance if I go down but not bulky all all. I'll take no padding and a few bruises over limiting my motion. I can wear them the whole ride and I don't even notice, sort of like arm/warmers. Crashed a few times on them and they don't show any signs of wear. Wish fox would release the sizing on these. I'm 6'2" 200#s and ended up with medium knee and and large elbows.
