I'm a slim guy, 6'0"/160 lbs. I bought a medium, which is sized correctly through the shoulders, but quite generous in the torso. Definitely not a slim fit.
I tend to run cold. Not the ideal body type for Wisconsin's eternal bitter cold, dark, windy winters. Last year I froze my butt trying to wear a down insulator with vest over it. This set up was not windproof or waterproof, and it leaked feathers everywhere. This year I decided to invest in a quality jacket that is functional, waterproof, durable, and (super hard to find) STYLISH.
The Fjallraven Polar Guide ticks all of these boxes. I've only had it a few weeks and already it has proven its worth.
-So warm! Tons of synthetic insulation, and no annoying feathers blowing sticking to my car, house, office, wife. Drop tail insulates my butt from my freezing car seat.
-Completely waterproof. Wore it for two days hiking in sleet.
-Looks great. Goes beyond the basic black puffer look which is so played out. I got the Olive color which is more brown than green A huge plus IMO.
-Durable. The G-1000 fabric feels like it will live as long as I do.
-Bulky and heavy. Built oversized, and all that insulation's gotta go somewhere!
-The hood is too big. Very snorkely and gives tunnel vision.
-Removable faux fur looks great, until the hood goes up. Then you can't see a thing. The fur also makes it difficult to zip all the way up and makes you feel claustrophobic.
Conclusion. You get what you pay for, and this is a piece that will last a lifetime. I wish I could say it's perfect, it's not. However it looks awesome and performs just as well. Bring it on, Wisconsin.
