I’ve got a Mavic Creek with some very nifty bike specific features.
The front zip is actually a two layered zip. If you zip both up, it’s totally wterproof. Unzip the outer layer and it opens up an inch wide mesh at the front (as far down as you want it by pulling the zipper up or down).
It’s got underarm pits.
The back expands with two vertical zips on each side of the back, which means you can wear your thin cambelback etc underneath the jacket as opposed to above it (if you got a sweaty back like me, having it under is much nicer). These backzips basically just works as an expander, so it doesn’t open up into your body…ehnm…so to speak.
This however only does go on when it pours down. I’m looking at something in between when it’s raining lightly (which will get you wet in the end) but you don’t want the very warm sweaty feeling of a proper hardshell.
I lurvs mine. Pricey though.
