Any suggestions for a summer jacket suitable for riding in high 30's & low 40's? I would like one that still has the armour, is cool(ish) and not cost an arm and a leg. Last summer we were getting 6 or 7 days in a row over 40. How abrasion resistant are the "mesh" jackets? It will be a while before I get back down to the bigsmoke so I'm trying to do research before I get there. I ride a cruiser so I prefer not to use a short jacket, if that makes any sense.
