We spent 25 hours on research, videography, and editing, to review the top selections for this wiki. Merino wool is some of the best of its kind because it comes from sheep who survive in the New Zealand Alps, making it remarkably warm, and it is sustainably sourced. We found women's long johns made from this superior material that are flattering, comfortable and will regulate your temperature during your outdoor adventures. When users buy our independently chosen editorial picks, we may earn commissions to support our work. Skip to the best women's merino wool long underwear on Amazon.
