If rain is possible (it's Alaska, duh), a lot of people have found out the hard way that most type of GoreTex, Kuiu, Sitka, etc type rain gear starts to leak after a few days of constant rain. When I did a coastal brown bear hunt at Wildman Lake with Butch King, he recommended Helly Hansen Impertech rain jacket and pants. This is the rubberized type slicker suits that you see commercial fisherman wear. On my spring bear hunt, it worked great! I had 10 days of sunshine, so I folded up the rain gear and sat on it. Fifteen hours a day x 10 days of "sit on your ass and glass", you need some padding.
