Hi all... I'm planning about a 10 day Caribou hunt in September (combination hunt so multiple caribou or species such as sheep or moose are a possibility). Some of the gear I have for deer hunting in central/northern Maine will do fine, some won't. A couple things I'm thinking of buying. One is the Cabelas Extreme Alaskan Outfitter Pack and Frame and the other is the Helly Hansen Impertech Guide Coat. Does anyone have any experience or reviews on these items?? From everything I've read on Alaskan hunting, it seems that Helly Hansen products are very highly regarded. Any and all suggestions would be appreciated. Thanks!!
