arm and leg protection

I need some recomendations for arm and leg protection. I want leg protection that protects not only my shins and knees, but the back of my legs (calfs) as well. It needs to be durable, comfortable and preferably breathable. I want protection for my arms from my wrists to my elbows with the same qualities. Please include where i may find these and approximate costs.

sixsixone makes good leg protection like this that’s really popular with unicyclists. I have a pair, and it’s prevented many an injury.

this is sixsixone arm armor. I haven’t ever tried it, but I’ve seen people with it and it looked like it would work fine.
