Nice light weight jacket that I can easily roll up and store in a pocket in my jersey. Works great when I need a little extra warmth on a chilly day or to help block some wind on windy days.

Great jacket, well made. I am 6'2", 180 lbs, and L fits me perfectly. I use it routinely for mountain biking and running.

It weighs almost nothing, and compresses to about 1/2 the size of a small water bottle, so you can always bring it along. I use it a lot in cold weather (<30F) and modify my layers beneath based on temp.

It is definitely NOT waterproof (and not supposed to be), and not even that water-resistant, though it'll do fine in light snow flurries.

This jacket runs small. I usually wear a large, but bumped up to an XL to allow for a base layer. Still too small. The cuffs are have very cheap elastic and does not compress at all. No pockets in the front.

Wore it once in 55 degree weather with a light base layer. Did not keep out any type of wind or retain heat. This product needs rethinking.
