I'm looking for something that will cut the wind out yet still breathe in temps from 20-50 degrees. I'm not really looking for waterproof as that means sweating and overheating.

I saw these on the Pearl Izumi site.
P.R.O. Softshell 180 Jacket

P.R.O. Softshell 180 Jacket - Pearl Izumi

This looks very close to what I'm looking for. If possible, I'd like something maybe a bit less form fitting so I could add a layer underneath if needed on the colder days.

It has a windproof front and a very breathable back panel.
I saw a similar looking garmnet at REI. They call it the Headwind Jacket.

Has anyone tried something like this to block wind? Does anyone else make something along these lines?
