I have had great success with Marmot and am happy to say this vest is no exception to their quality as I absolutly love it! I am 5'9", 145 pounds, athletic build and the medium vest fits perfectly. There is plenty of room to layer a fleece underneath and the length is just right (longer in the back which is great). I would agree with the "water-resistant" label. I was out during light rain and thought it held up well though I don't know how it would do in a downpour. Fleece collar and pockets are a wonderful addition. The rainwater blue is a beautiful color!
