light weight and super breathable

    Okay this thing does not weigh much. It says 3.5 ounces but I think the tags weigh that much. stuffed in the pocket is so tiny I could not believe it. wore it on some chilly runs and keeps the wind off you but did not get clamy at all even used it in a rain snow mix and kept me bone dry. Don;t think it would in a downpour but thats not what its for. Really like the material in the sleeve opening for balling up your fist when its cold out. This thing is great, green color is sweet!
