Hey - I fell off my radcity 4 last week (victim of an edge trap in the cement) My helmet and gloves saved my head and hands! I had a 3 inch crack in my helmet and did not feel a thing on my head.
However, I broke 2 ribs and have some road rash on my shoulder. When I ride my motorcycle, I ride with full gear. I'm now looking at beefing up my bicycle gear.
I am looking for a lightweight breathable long sleeve shirt with elbow and shoulder armor. Any ideas? I mostly ride paved bike paths and streets and a little gravel.
Search the web for downhill bicycle race. Lots of photos of the type of clothing that could be suitable.

A Google search for "lightweight cycling protective clothing" brings up some nice choices, including options on Amazon. Might pick some up myself since I'm still recovering from my last crash, lol.
