I read this article and it talked about Icebreaker and merino wool explicitly when traveling.
Can somebody share what Icebreaker is and what merino wool is?
Is it just the brand or something else as well?
I ask as Icebreaker is told/shared as something to be worn outside, an Icebreaker long-sleeved shirt rather than just as an underwear to minimize odor while traveling as well as insulation against all types of weather.
