I wear a Joe Rocket mesh jacket in the summer. Seems OK up to about 80 degrees, maybe a little over it it's a longer ride to keep the air moving. Sometimes it's just too darn hot to wear a jacket.

A mesh jacket is the way to go up to 90 degrees or so
after that, wind chill works in reverse, and more exposed skin heats the body faster than sweating can take care of
I wear mesh up to 90 or so, after that it's back to leather, at least for highway riding, as it's actually cooler without all that hot air moving across the skin at 70 MPH

Joe Rocket stuff never fits me right, I use a Firstgear mesh jaket

How is the fit on these jackets? I wear a 16(neck)  32(sleeve) dress shirt, medium in polo shirts, and have a short torso. 32" waist.  Wondering if a M is a little large for me or if I could comfortably get into a S.

And color options...Blue, naa.  Red, naa. Silver, maybe. Black, my preference since my bike is black.

Cheap Chinese mesh thing..... I figure its at least a little protection.

Yeah, old_rider, this would go perfect with your new windscreen    

We'll be looking for you on the 6 o'clock news cleaning up crime in the FL panhandle.

I have the 2009 version of this http://www.motorcyclegear.com/street/jackets_and_vests/mesh_jackets/first_gea... bought from the site I posted. I've had it since 2009 and it's holding up really well.  They tend to run a little big but the sizing chart is accurate.  My only real complaint is the liner doesn't go all the way across so you get wet where the zipper is but if it's raining hard enough for the liner, I'll put on my rain jacket over it.

Thanks all!  

As luck would have it (in a good day for a change) I stopped by the local dealership just to browse and see what they had and wouldn't you know, they had the Joe Rocket Velocity mixed in there. One 2XL and one S, both in the grey/silver flavor. I tried it on with the removable liner and it was snug, not tight, but snug. So wearing it without the liner will be slightly more comfortable.  And, the S has a short enough torso where it doesn't bunch up in the front like my thick and bigger Detour winter jacket does.

Retail was $129, and I really wanted all black. I stared at it long enough so the guy let me have it for $99 out the door to get it off the shelf.

So, grey/silver is my new favorite color. Hope to ride tomorrow if it doesn't rain and put it to the test.
