Amazingly light rain shell - Rab Boreas Pull-On - Mens

I got this to wear on cold rainy days, and pulled it out to use over a fleece shirt when I ran in the snow a few weeks ago. It kept me dry while I ran, and kept me toasty warm. The jacket itself is quite thin, but stretchy, and does a decent job at blocking some wind (in addition to being waterproof/resistant). It breathes well, too, unlike some raincoats (which are like wearing trash bags). The first one I bought fit somewhat close and I returned it to size up. For reference, I'm 6'6", 235 lbs, and usually wear a XL in most RAB jackets (but I'm a XXL in this).
