For big adventures - and bigger opinions! These merino wool base layers are made for outdoor school, ski days, long travel days, and the playtime that doesn’t end when it’s cold out. Buttery soft (so they actually keep them on), warm without bulk, and breathable enough for running, climbing, and sitting still when they have to. They pack down small, layer easily, and the grow-with-me fit plus reinforced high-wear spots mean they’re in it for years, not just a season.
