Where will you take it?
Base layers do their quiet work where the temperature swings hardest — warm valley mornings and freezing high passes in Nepal, crisp ridgelines in Japan, long days on the Central Asian steppe. Merino handles days of wear between washes, which matters on a two-week trek with our sister company X-Trekkers.
