I have not tried Impertech yet but the Precip jacket i have has pit zips so your good to go(and its a nice dark green color). You just cant leave them open if your in a downpour. It cuts the wind great also, my Gore-tex feels like i have a mesh jacket on, the wind goes right through it. I guess you have to pick and choose how you want your gear to perform as i have not seen a perfect rain fabric yet(need to try some event though).
