One of the instructors at my MSF class said that some magazine or something did a test of three different types of jackets. They dragged em down a street i guess, and supposedly the leather one came apart well before the mesh ones. I have a mesh/rocktex one. It has all kinds of armor and isn't as hot as the leathers. Mesh is a must down here, it's so damn hot and humid. I also recommend the Alpinestars SMX Air Carbon gloves. They are lightweight, breath awesome, and look badass. They are priced decently at around $55. Well worth it. You can actually feel the air coming through the leather and blowing on your fingers...very nice.
