Alot of guys scoff at it, I sure did when I first heard it. But I decided to try it one year while hunting. Lots of walking in deep mountain snow and temps in the single digits... Feet sayed warm, dry, and not a single blister. Ive been preaching it ever since.
Back when selective service/draft was going on, some guys would wear silk underwear to the physical. They would be sent home with a 4F classification. ` 4-F is a classification given to a new U.S. military registrant indicating that he or she is “not acceptable for service in the Armed Forces” due to medical, dental, or other reasons.
They wore silk underwear because they didn't want to be drafted. It was assumed they are gay; which disqualified them. They only wore it that one time. Some guys wanted to be drafted because they didn't qualify to enlist. Being drafted was easy as long as a person could pass a simple physical. Some married guys had a wife and several children and didn't qualify to enlist because of too many dependents. Those guys would go to the draft board and volunteer to be drafted and could leave in a couple of days. The pay wasn't that good, but the benefits on active duty were very good for his dependents, plus a retirement in 20 years with lifelong healthcare.
I have better luck with Duluth trading than carhart, I just bought three pair that was mentioned suspect zero. the store is at wixom road and 96, sometimes you can catch a sale on them and save some money.
Dress in layers , and look at getting a thin windbreaker set as a top layer, I got a base layer of compression long sleeves ,a pair of sweats/flannel fleece from sams, and a thin windbreaker jacket and pants..then Fr because of marathon.. keeping the cold wind off you is key!!
Eddie Bauer has the down quilted long johns on sale now. Tegular long johns under thise on bitter cold days. Loose pants, shirt, coat hat and gloves and you are ready to pullsbury dough boy to work. But you will be warm. Dressed this way on a river piloting a air boat at -5, face got cold but everything else was warm.
I’m a fuel hauler too and can relate. When it’s really cold out, I wear a base layer of midweight merino longjohns that I got at the local farm/ranch supply store. FR jeans, FR high-vis rain pants as needed. Long-sleeve button-up denim shirt, fleece vest, flannel-lined canvas jacket, FR high-vis rain shell. I can easily adjust/layer from in the cab to the outside. I also carry multiple beanies, a balaclava, multiple gloves, and Hot Hands (I bought a case off Amazon). I wear two pair of socks - one pair are over-the-calf normal weight Wranglers and the other pair are carhart boot socks over those. Waterproof pull-on Ariat western boots. Carrying a bunch of stuff is a mild inconvenience compared to the alternative.
