My favorite all around hunting boot has been my wolverine King Caribou boots. This will be my third season with them and i have NO complaints. Theyre 800 grams thinsulate, and i wear them from opening day all the way through goose season in february. They can get a little warm in early season, but ive never been uncomfortable. Extremely waterproof, great lookin camo, well built, stood up to everything ive put them through. So, i dont think you can go wrong with anything about 600 to 800, but im one of those people that wants to be toasty warm on stand, not just having to tolerate a little cold.
