I have been using Carhartt Arctic Extreme gear ever since I moved to Alaska in 2000. I have worn them while working on the North Slope, while chasing fish and game all over the continent and still wearing a set of them today back here in WI. Its breathable, very warm, well padded, but not entirely waterproof. In the end I don’t think any gear is 100% waterproof. They stay dry for about the first three or four hours of a saturated rain, then you can expect to start feeling moisture inside, but your still warm. I made it all day in the rain with no shelter twice in the past two weeks on WI lakes. The Arctic Extreme varies from your typical Carhartt bibs and jacket using a different material in the outer shell and even more blanket insulation. The best feature is in the bibs. They have a split zipper front which comes in very handy for those warm days and cold nights. Instead of shredding clothing while being mobile and working up a sweat I simply open the jacket and the front of the bibs and keep the perspiration down. The other nice thing is they are alot less expensive than the mustang suits or the ice armour. You should make sure though that if you purchase these that they say Arctic Extreme on the label.
