One other thing to consider..... You may want your riding gear to also be your rain gear. Is the outer shell the waterproof part, or is it the inside liner?
I wore some Olympia stuff for a year or two, and generally liked it. BUT... the liners were the waterproof parts, so in the summer I was either not protected from rain, or I was too warm.
Personally I prefer the outer shell to be the waterproof part, and then I can layer under it however I want based on expected temps.
I also prefer a pant liner that is worn as a layer, but not attached to the shell pant. I think it is easier to get on and off and move around if the liner is not attached to the shell.
