Frequently Asked Questions (FAQs)

1. Is wool a good base layer?

Good base layers are made from synthetic, wool, silk, or bamboo fibers—more on each option below. Avoid cotton, which takes too long to dry and pulls heat away from the body, which will leave you cold and uncomfortable.

2. Is merino wool best base layer?

Merino wool base layers are best suited to mild – cold weather, or stop-start activities like hiking and climbing. Merino wool's natural breathability and temperature control properties keep you more comfortable in a wide range of conditions, even when you slow down.

3. Should wool base layers be tight?

A base layer should be tight fitting so it traps air next to the skin and insulates the body from the cold. It's best to buy base layer clothing in the size you normally wear as they are made slightly smaller with this in mind.

4. What is the best base layer for extreme cold?

Merino Wool: The other more common type, a merino wool base layer is made of a gentler type of wool that's less irritating to the skin. It excels at regulating body temperature, so it's great for insanely cold weather but won't have you overheating when things start warming up.
