Well, I don't do snowpants, lol. Yes, I'm weird. However...
Favorite boots are steel toed boots that I have a set of spikes for traction that I can put on and take off very easily. The boots are from Farm And Fleet. I've had them for years and LOVE them. I wear them in the summer, winter, whatever weather. If you are susceptible to frost bite though (I get frostbite very easily because I've had frostbite before in my toes) you may not want STBs... I just find them very versatile and handy as I get hurt alot and I like having toes. I wear extra socks when I'm going to be out for a long time so that the steel doesn't freeze my toes off too quickly.
All my coats, ever since I've been a kid, have been Zero Exposure coats. They work very well for me and you can find them anywhere.
Yeah... I'm very simple when it comes to my gear lol. But it all works really well.
