Warmth without compromise!

I'm not a mountain climber but I sometimes have to sit in a cold environment for extended periods. This suit is everything I expected. Its very warm, the baffles leave zero cold spots. The hood allows for any adjustments you could need. The details including zippers, pockets, and materials are all top notch. I expect many years of reliable warmth, as I've come to expect from Mountain Hardwear.

Alaska Worthy

I bought one last year and I have worn it a few times. Its lighter in weight than the Northface bee suit. Its an attractive, visible color scheme against the snow, its very, very warm and has ample packets but it runs way bigger than the measurements guide and looks very bulky and almost sloppy. I had to belt mine. The too long legs can be stuffed into boots, but the legs are really bulky too. I'm a true medium and this medium suit ran really large. I had to belt it, sleeves and legs too long, fit in the shoulders, huge everywhere else.The quality is spectacular. Its really nice they are now offering a woman's fit option this year. Other companies do not do that.
