Frequently Asked Questions (FAQs)
1. What are the warmest thermals for extreme cold?
Merino. Merino baselayers are considered by many (including me) as the best type of fabric for extreme cold weather long johns. Merino base layers are great for almost all kinds of weather conditions; they're great at quickly wicking away moisture and are naturally odor-resistant.
2. Should thermal underwear be tight or loose?
While many love loose-fitting clothing for comfort, they don't always keep you warm. Thermal underwear are made to fit close to your body like a second skin. How Tight is Too Tight? Also known as a base layer, thermal underwear is supposed to fit tight.
3. Does thermal underwear keep you warm?
