"There are sweaters, and then there's this."
I spend a lot of time at altitude in some pretty hostile places, Afghanistan, for example. Hostile not only because there are people that don't really care for me, but also the weather. Intermittently mixed with deep cold and damp wintry conditions, it's a paine in the arse to find even a single article of clothing that's what i would view as "tolerant." Enter Prana Men's Sherpa Crew Top. My wife bought it for me, and when i got it, I had thought....man this is heavy....this is going to get wet and weigh fifty pounds. Prana people....I was wrong. It is a dense and heavy sweater, fairly wind resistant, and doesn't really suck up the dampness from the air all that much. More importantly, without intending to disgust, but i didn't wash mine for several months....didn't get nasty, didn't smell funky, more importantly it's held together quite nicely. Just bought a second one for when i decide to start living a normal life back home.
