Description

If you’re new to merino, start here. The Men's OG Long Sleeve is the foundation of any good travel, training, or daily wardrobe. Built from 190gsm of breathable, temperature-regulating merino, it keeps you warm in the cold, cool in the heat, and comfortable through all the in-between.

Whether you're packing light for a trip, heading for a run, or layering up for a snow mission, this is the shirt that does it all—without the bulk of traditional base layers.

Merino 365 garments naturally flex and move with you, offering comfort without restriction, even when worn tight to the skin. Soft enough for next-to-skin wear and tough enough for repeat use—this is your daily driver, year-round.

Join the thousands who’ve made this their base layer of choice since 2016.
