Great windbreaker in cool/cold weather where it’s windy or slightly rainy / drizzly. The materials are great too - environmentally friendly rainproofing, YKK zippers (this is not advertised or on the product page but was a pleasant surprise), and it just looks really good (form fitting medium size for me). Really like the blue.

Super Lightweight
I searched for quite a while to find the ideal windbreaker, and this is the closest I’ve come. The jacket features two zippered hand pockets, which are rare in this weight class and a great bonus. I’m 6’1”, 180 lbs, and wearing a size medium—no need to size up or down. The fabric has a bit of stretch, which is appreciated when layering underneath. It breathes well and doesn’t trap sweat, and the breathable back panels do a good job of letting moisture escape. I haven’t tested it in light rain yet, but I would prefer some type of DWR finish.
