The single most common question we get about our knitwear is some version of “can I really wear this three days in a row?” The honest answer is usually yes, and merino wool is why.
Merino fiber has a natural crimp and a slightly acidic surface chemistry that’s genuinely inhospitable to the bacteria responsible for body odor — unlike synthetic fibers, which trap moisture and let bacteria thrive on the surface.
It’s also naturally temperature-regulating, which is why the same sweater that keeps you warm on a cold train platform doesn’t leave you overheated the second you step inside.
