I just bought a Joe Rocket Cleo jacket and pants. They are for warm weather riding. The jacket is armoured mesh, with a zip-out waterproof/windproof liner. The pants have armour in the knees and bum (although I have to admit in my female vanity I took out the bum pads) and mesh on the front part of the thighs, so they don’t get to hot. I wore them to the movies last weekend and didn’t overheat. The two pieces zip together at the back for longer rides when you don’t want any wind getting in. I am very happy with my purchase and they are very comfortable to ride in. My bike shop had a deal on the two pieces together; i paid $350 CDn for both.
Edited to say: as for helmets you HAVE to go try on different brands. You would be amazed at how differently they all fit.
