Great for spring/summer showers. Very lightweight, stuffs into its own pocket. Its not very breathable, so you may sweat a bit during heavy activity. Fit is good, I'm 6'1 200lbs with a 44" chest and the large fit me well while still having some room for layering. Sleeves are long with velcro cuffs to keep you covered with full range of motion for riding a bike or other activity.
