Unfortunately had to send this jacket back. Felt very warm but sleeves were so long I could not wear it. If the sleeve had an elastic cuff I would have kept it but without it there is no flexibility in the sleeve length. I ordered a small and wear a 15/32 in a shirt. I am a slight build but it was still a little snug in the shoulders.
I want to describe this jacket because the photos don't really do it justice. The exterior feels like a windbreaker mixed with spandex, while the inside is fleece. So it's soft and warm but also waterproof, which is a rare combination.
The fleece is really dense and warm, which is surprising considering how light weight the jacket is. I love the soft pocket liner. The zippers don't jam.
A small word of caution, though- the photo of the khaki/moss peat green is a little bit lighter than how the fabric appears in person.
Nice quality, but a snug fit. I'm 6'1", 225lbs, and usually wear an XL no problem. This jacket was fine in the shoulders, tight in the chest, long in the sleeves, and short in the body.
