I just researched and bought the Alpinestars Cape Town Air for $120 on closeout (I see it has gone up in a price a little now)
Access Denied
I chose this jacket for three reasons: price, mesh, protection.
I really like the jacket, and it does flow a ton of air, however, I added the optional chest and back armor inserts which does hinder some airflow but well worth it for the amount of protection it provides! I don't know any other mesh jacket that allows for chest protection! It's also a 3/4 length jacket, which you may or may not like. Personally, I like the versatility and added protection. I think the mesh is placed properly and out of the way in the event of a fall. My only gripe is the collar sits a little too tall for me, but I'm hoping it'll grow on me. I run hot and I am comfortable at speed with this jacket. Since I ride rain or shine, it's nice that I can fit the rain liner in the back pocket.
The only other jacket I considered was the Tourmaster Sonora Air since I was only interested in a 3/4 length mesh jacket this time around, :
Access Denied but i have no experience with it other than what is advertised.
I also still rock a Joe Rocket Supermoto leather/textile jacket around town. This was actually my first jacket over 10yrs ago! I've crashed numerous times in this jacket without injury and it still looks great and flows tons of air! I think they're cheap now, too:
Temporary Insanity Deals
Many years ago I hit the pavement with an all mesh jacket and while it prevented some injury (elbow pads), it still tore apart and I got very bad road rash on my sides/back. Be very careful what you choose!
