I don't have that specific jacket, so I can't say definitively. I have a one-piece R3 suit. It is unlined, so it's not too bad in hot weather. Here's the thing: On a Motorcycle in hot weather, you are going to be hot.
I've ridden with all sorts of gear over the years, including in a T-shirt just to see if it was any more tolerable. The T-shirt (besides offering no protection) was the worst, because your exposed skin sunburns, in addition to dehydrating you more quickly.
I've had mesh jackets and pants, and if they are quality pieces, they are still probably best for riding comfort in extremely hot weather. The downside is that they offer less protection from roadrash in particular.
Next would be textiles like Aerostich stuff. I've never crashed in mine, but I've seen the effects of crashing, and how well the material holds up. Like everything, it's a compromise. Better than mesh, not as good as quality roadracing style leathers for protection.
The hottest I've ever been on a bike, was riding in the desert southwest in non-perforated full roadracing leathers. The big thermometer in Baker said 117°F. I thought I was going to die. I found a garden hose and literally soaked all of my riding gear, including my helmet. The short-lived cooling effect allowed me to get to Vegas, without dying of heatstroke.
