This wiki has been updated 17 times since it was first published in February of 2017. The advantages of Merino wool include powerful wicking, elasticity, odor control, and longevity. The material is, therefore, well suited as any type of underwear, and should be considered by people who live in colder climates. The primary difference between Merino and other wool is that the diameter of each strand of fabric is much thinner, which provides a host of benefits for textiles. When users buy our independently chosen editorial recommendations, we may earn commissions to help fund the Wiki. Skip to the best men's merino wool long underwear on Amazon.

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.
