Does the job. Keeps the nip off and adds a layer of protection from the elements when I've been on the top of the hills and rock face.
This product does exactly as the description says. It is incredibly light and packs down very small, so can be thrown in a bag and forgotten about until needed. It is wind resistant, and water resistant in light rain (have not tested in more than drizzle, but feels unlikely to hold up to more than a light shower). The fit is good/true to size. Delivery service from EB was quick and efficient.
Great service and really good jacket.
