Spats or gators are the things that keep you pants legs sealed. I finally got some flannel lined blue jeans this year! :thumbsup: Just like wearing a pair of pajamas inside your jeans.
One thing I've found over the years is its easy to put on too tight of socks or two pair of socks and then squeeze them into too tight boots. It cuts off the circulation in my feet. Many years ago I switched to a good pair of thick socks and large boots with felt liners. They are loose enough to allow my feet to move and they let the socks expand and do their job of trapping air to insulate rather than squeezing the air space out and cutting off my circulation. Some day I'll get a pair of mickey mouse army boots for ice fishing, but I don't need them at present. My feet haven't gotten cold in many years.
Typically, if I'm going to sit in the cold for hours and hours, I'll wear:
A pair of silk long underwear bottoms and long sleeve top (or under armor brand instead of silk).
A pair of thick, loose socks over the long underwear legs.
A T-shirt.
A pair of flannel pajama bottoms.
A sweat shirt.
A pair of carhart coveralls.
A carhart jacket with integrated hood.
Good boots with felt liners.
A silk balaclava.
A knit ski mask that goes way down my kneck.
A pair of socks on my hands with finger holes cut out to keep the breezes out of my sleeves.
A pair of winter welder's mittens....
I can't put my arms down!!!
