When I go ice fishing, I usually were a pair of thin silk long john top and bottom, a T-shirt, thin sweatshirt, flannel lined jeans, a hoody. One pair of thick socks. Then my carhart coveralls. For footwear, if its over 10F, I just wear my sketcher waterproof hikers. If its 10F or under, I'll switch to some snowmobile boots with removable felt liners. I'll slip a carhart jacket over it all if I'm sitting outside for more than 4-5 hours. But a good knit hat and some fingerless gloves and I'm all set. I'll throw on some welder's mittens if the wind is blowing. I'm fortunate that I really don't get cold all that easy. I tend to grow out a bear in winter. I keep it short, but long enough to hold my face mask off my skin. I think it ads a small layer of dead airspace and really makes a difference.
