Merino 250 Classic Thermal Base Layer Crew – Kids'

Built for cold-weather adventures and active kids who run hot and cold at the same time, the Merino 250 is our go-to midweight base layer for young athletes. 250g merino wool regulates temperature naturally and fights odor without chemical treatments, so it stays fresh across multiple wears. It works equally well under a puffy on a winter hike or as a standalone layer on chilly morning starts.

• 250g merino wool weight hits the sweet spot between warmth and breathability — not too heavy for active movement, not too light for real cold
• Natural merino fiber wicks moisture, regulates body temperature, and resists odor without synthetic treatments
• Crew neck construction layers cleanly under shells, softshells, or insulating layers without bulk or bunching
• Built for cold-weather trail running, camping, hunting trips, and any outdoor activity where kids need a reliable first layer
• Available in Black — a versatile base that works under any outer layer and hides trail grime well
