Smartwool Merino 250 Baselayer Crew Boxed

This 250-weight merino base layer is the foundation of a versatile winter layering system. Knit from 100% merino wool, it naturally regulates body temperature across changing conditions, wicking moisture away from the skin while remaining breathable during high-output efforts. The fabric's inherent odour resistance also means you can keep wearing it day after day without the quick buildup of smells—just air it out overnight and it's ready again.
