ok I have a gift card for Performance bike that I got as a gift. I thought I might use it to get a jacket for colder temps.

My question is arm pit vents vs back vents? Which is better? which allows for more temp control? Should I try for a jacket with both?

I would need the jacket mostly for the morning commute and maybe some afternoons. I live in Tucson so it rarely gets much below freezing, and even rarer still that it stays that cold all day.

Below are 3 jackets I saw at my local Performance store and I am considering, just not sure which would be best.
