Cold, wet and i'll fit

I've used it once or twice and have initial impressions
Size Bought:
5' 11"

Got the jacket and the first time using it got caught in a rain storm a couple miles from the car and about 9000ft above sea level. The jacket got soaked through and the water did not beed up at all. Got super chilled and borderline hypothermic. Fit is not good either, tight in the underarms and chest. Returning it and going with something else. Unacceptable for a $360 dollar coat. What happened to Mammut?
