This is a great knock around jacket. It’s ultralight, but super warm, even though it’s not lined with down feathers, but instead a synthetic material (keeping with Patagonia’s reputation for using recycled materials). I buy a size up so I can wear a heavy fleece under it. It has a quality zipper, and nice deep pockets that also zipper closed so you won’t lose your gloves. The inside pocket is also quite handy to put a ski cap….classic Patagonia. This is my second one, as I wanted to have it in another color. Anybody who shops for Patagonia knows it’s hard to get their clothing at a discount. They had this jacket at a fantastic price, so I jumped on it!
