We spent 25 hours on research, videography, and editing, to review the top selections for this wiki. Merino wool is prized because it comes from sheep who survive in the New Zealand Alps, making it remarkably warm. Plus, it is sustainably-sourced. We found women's long underwear made from this material that are flattering, comfortable, and will regulate your temperature during outdoor adventures. You'll love layering these beneath outerwear, or lounging at home in them. When users buy our independently chosen editorial picks, we may earn commissions to support our work.

A wandering writer who spends as much time on the road as behind the computer screen, Brett can either be found hacking furiously away at the keyboard or perhaps enjoying a whiskey and coke on some exotic beach, sometimes both simultaneously, usually with a four-legged companion by his side. He hopes to one day become a modern day renaissance man.
