OK, this is a cycling piece, but I have the jacket and it doesn't swoosh. I'm contemplating buying this vest. The front is wind block and the back is a pretty thin lycra; perfect for layering. I think it would be fantastic for running on chilly breezy days.

This also looks nice for running. I love the Sporthill stuff for skiing; I suspect it would be nice for running as well. Rated for 0-40 F.

I like vests. Jackets are OK for the coldest of days, but I'm with RedCanny. I get too close to imploding if I wear a jacket unless it's in 20s. That "new" lighweight wool (long sleeve) and a vest...perfect.

I have a Marmot driclime windshirt and it's really flappy. OK for backcountry skiing but not running. Though the flappiness may be a function of having a size too big.
