I won a JR mesh in a $5 raffle and I feel comfortable riding in it. I read a lot of reviews on it including reviews from riders who went down in it (70-80mph crashes). Every rider commented that the jacket protected well under those conditions, but that it was a 1 crash jacket. No one reported any of the protective pads coming out of the jacket, only that the jacket was heavily damaged after the crash.
I figure its a good investment, If you are like me and know you aren't gonna throw on a leather jacket in 90+ degree weather. I did a 400 mile daytrip in mine and on occassion i would wet the t-shirt i had on under it, and with the wind blowing through the mesh it really helped..
If anything happened to this on I'ld buy another for the price, I bought the matching mesh pants. When the funds are there i may invest in a perfed leather jacket.... but until then i'm satisfied with my JR suit.
Oh one thing this sucker provides no warmth if you get caught out on a cool night after riding all day --- I've learned to keep a sweat shirt or windbreaker in the tank bag during the fall.
