This is a great jacket if there is mist or light rain. Hiked in Oregon in light rain for over 5 miles and stayed dry. Fits a bit small but the jacket stretches.
My wife and I each own one and use it for hiking and backcountry skiing. Breathes well, wind and water resistant and a great jacket when a hard shell is not needed. Negative is that the 2 hip pockets are useless with a pack belt. Really designed more for city use or walking one's dog in that regard.
Like your favorite hoody, but more versatile. I'm a true size 6 and the S fit perfectly.
This light weight jacket is perfect for climbing, very stretchy and comfy.
