I have some Irish Setter 400 thinsulate that are close to perfect for general cold weather hunting and walking, don't feel real heavy.
Have used them sitting in a stand in Kansas when temp was in the teens, they were OK with a sticky hot toe pad stuck to the bottom of my socks.
Also have a pair of 1000 gram Danner that are not as cumbersome as pack boots but are noticeably larger than my 400 grams. Have used them in Alberta stand hunting when it was -15f with hot toe pads, and they were OK.
