"Incredibly light weight yet windproof and sheds light rain."
This shell is amazing, light as a feather and very comfortable. I run outdoors most days and I find this shell to be an amazing piece of technology. It is windproof, super lightweight, and sheds light rain. It really works well when layered. Even after a one-hour run, this shell is still comfortable while sweating. It is freaky thin and well made. It folds into a very small packet and can easily be carried. You can't go wrong buying this!
