Mons Royale Folo Merino Tank

What Our Gearhead® Experts Are Saying: "I’ve been wearing the Folo Merino Tank as my go-to baselayer for trail runs and travel. The Merino Air-Con fabric is surprisingly light and breathable, even when I’m working up a sweat. It fits close to my body without feeling tight, and the scoop neck layers easily under midlayers or a pack. If you want something that manages temperature across seasons, this tank is a solid choice." We reach for the Mons Royale Folo Merino Tank when we need a versatile foundation that works from high-output hikes to quiet afternoons in camp. Mons Royale designed this tank with Merino Air-Con—an ultralight, ultra-breathable fabric that naturally regulates body temperature, wicks moisture, and resists odor so we stay fresh and comfortable no matter where the day takes us.With its slim fit, double scoop neckline, and self-binding details, the Folo Tank slides seamlessly under technical layers or stands alone in warmer weather. From dawn patrol missions to weekend getaways, it’s the essential base we rely on year-round.
