What are the positives and negatives of these two. Which is worth the buy. Right now, I just have a mesh Joe Rocket for commuting around town. Live in AZ, so the heat is rather horrible during winter. But winter is different. Looking at the Alpine Stars, but don't know what way to lean with them. Like their compressed mesh jackets, but don't know EXACTLY the difference between the compress and "regular" mesh, unless its just a nicer way to put mesh. I want to have two different jackets for different seasons, because yes, it can feel cold to me in Arizona in the winter. So if you could just give some replies on the differences, positives and negatives that would be great. Thanks.
