I do love this jacket. The color is beautiful, the shell is light and silky, the fit is very flattering. It's quite breathable. I bought it at a really great sale price, it's definitely not worth full price.It's not that warm, though. My Cirruslite down jacket is definitely much warmer, despite a similar temperature rating. This is because the real reason down is a good insulator is the loft. In this case, the loft is intentionally reduced (for the sake of vanity, lol) and the ability to insulate suffers for it. A "moderate activity" rating of -15F is a joke. Maybe cross-country skiing uphill on a sunny, windless -15 day? Still, it's great for easy hikes in 30 degree temps, great for hillier hiking in the twenties and great for the first ten minutes of cross country skiing in the teens, after which I take it off and stuff it in my pack, and to put on when back at the car.Did I say that I love this jacket?
