This is much thinner than I thought it would be, but it's as warm as I hoped it would be, so I guess that's a win. I'm really happy with this as a mid layer under a jacket that can break the wind and keep me dry. In spring weather, I'm sure it will be great as a jacket on colder nights and days. My only complaint is that small amounts of the insulating fibre seems to be poking out at a couple locations (almost like down). It is really tiny amounts though. I doubt it will cause any problems.
