Looking at them, they don't look like they breathe- you'd get as wet from sweat as rain. i would recommend something that breathes for comfort- like Cabela's Dr Plus- it's in their Rain Suede line for about $100.
I don't recommend anything from Propper- I was issued stuff made by them when I went to Iraq last year- it was all cheaply made and only lasted a couple weeks before I had to buy my own stuff.
