I'm from Texas and am embarrassingly ignorant on all things cold weather-related. Taking the family to Jackson Hole this winter where we'll be doing a lot of longer outside-related activities, but nothing that is too exertive. We won't be skiing or snowboarding. We'll be taking a snowmobile tour of Yellowstone, doing a sleigh ride through the Elk reserve, snow tubing, maybe some light snowshoeing, things like that. The two guided tours we are taking are 12 hours, and 8 hours respectively. I've also rented some snowmobiles to do some unguided rides that we could potentially be on all-day. Thought I could just go to Amazon and get some longjohns and be set, but once I got there, I discovered the whole world of "layering". I'm seeing base layer this, mid-layer that. Then they have different "weights" of the base layer, so they have a mid-weight base layer, which isn't to be confused with a mid-layer. And this stuff isn't cheap, some of the more outdoor known brands you can spend $120 on a base layer shirt alone. So, I understand the concept, you put several layers of clothes on and several layers are better than one thick layer at keeping you warm. But is there any reason, in my case, to need to spend $200 a day on what amounts to underwear? Having several days worth of this "base layer" underwear for each of us could quite literally cost thousands (emphasis on the s) of dollars (I'm not certain the cabin has washer/dryer). So before I dig any deeper, having never been in very cold weather for any real length of time, is this layering system necessary? Or is it just a marketing thing? Is this one of those things where I'll really wish I had it an hour into an 8-hour snowmobile ride, or can I just throw on some long john's, a long sleeve shirt, a thick hoodie over that, and a big winter coat on top and some flannel lined pants and be just as well off? If it is necessary, is the cheaper stuff just as good as the more expensive stuff? Carhartt has some base layer shirts for $40, will it do just as good as a Merino Smartwool base layer shirt at REI for $120? Take it easy on me, took a lot of courage to ask the OB about clothing, but I don't want our vacation to suck because we brought the wrong clothing.
