GORE WEARFormula Vest Mens

I've always had good luck w/Gorewear products which I almost always purchase from the Seller Backcountry.com. I'm a male 5'8" 153 lbs with a 34~35" chest and a Small fits me perfectly.The vest is made with GORE-TEX INFINIUM and GORE WINDSTOPPER in the front. I've ran in winds so far from 9 to 15 mph and the vest performed as expected. The vest is more for the Spring and Fall than Winter. I've paired it w/a Mid-layer shirt when temps were in the 40's (F) or just a regular running shirt when temps are in the 50's (F) and didn't feel over heated on runs lasting up to two hours.The back pocket is accessible while on the move. I like that I can stash things there and get them out w/o having to stop running.Shipping was very fast and I'm happy I purchased this item. It fits that "in-between" weather when I don't want to go out in running jacket, but it's windy enough to make wearing just a shirt a bit too chilly.
