This wiki has been updated 13 times since it was first published in February of 2017. 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 help fund the Wiki.

Editor's Notes

October 15, 2018:

We expanded the list substantially to ensure there are light, mid, and heavyweight options in tops and bottoms. We also focused on more form-fitting choices.

A wandering writer who spends as much time on the road as in front of a laptop screen, Brett can either be found hacking away furiously 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 has been a professional chef, a dog trainer, and a travel correspondent for a well-known Southeast Asian guidebook. He also holds a business degree and has spent more time than he cares to admit in boring office jobs. He has an odd obsession for playing with the latest gadgets and working on motorcycles and old Jeeps. His expertise, honed over years of experience, is in the areas of computers, electronics, travel gear, pet products, and kitchen, office and automotive equipment.
