Frequently Asked Questions (FAQs)

1. Does wool make 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 wool The warmest base layer?

Is merino wool the warmest fabric? Merino wool is warmer than other fabrics relative to its weight. Merino wool is incredibly efficient at locking in heat, which means a merino wool base layer will keep you warmer than a synthetic if they're both the same weight (basically thickness) of fabric.

3. Should wool base layers be tight?

Base Layers don't have to be too tight, the benefits of a tight fitting base layer can be seen in the Compression fit designs. Some base layers have a more relaxed body fit that are deliberately designed to sit more loosely on the body.
