That's one of the reasons I am attracted to that Taiga jacket. It has a giant vent in the back.

Turbine, I lived near the Pentagon until a few weeks ago when I moved outside the beltway. I started working out west and the 19 mile each way commute was killing me. I needed to move to get it down to a manageable distance. I was hoping to find a place with a 12-15 mile commute each way, but mine is only 7 right now.
