RE: sportsmans guide, guide series hunting boots
keep in mind this is a second hand opinion, but a good friend of mine that I was in a club with for several years bought some Sportsmans guide guide series boots and his words were ''they are about as comfortable as cinderblocks'' andthey did not hold up well either, they barely made it through the deer season and weren't worn again until they had thier final come apart while fixing up duck blinds, the next year.
I'm not sure what you're looking to spend, but just search the net for closeout hunting boots, i've found my deals that way and on good boots and clothes.
lastly, 2000grams? are you hunting the artic cirlce? Not being a smart @$$ but remember that those grams convert to pounds and 2000g is over 4 lbs. so your getting into some seriously heavy boots. But, to each his own.
Good luck.
