What Our Gearhead® Experts Are Saying: “I use this as a next-to-skin layer for warm days when breathability really matters. It’s incredibly light, dries fast, and the mesh back keeps airflow moving without sacrificing coverage.”When the day starts early and doesn’t ease up, the Bella Merino Tank keeps us comfortable through every push. Designed by Mons Royale as a high-performance base layer, it’s built for warm conditions where staying cool, dry, and unrestricted makes all the difference. From long climbs to sun-exposed miles, it delivers reliable comfort without extra bulk. The Merino Air-Con fabric blends fine merino wool with nylon and elastane to regulate temperature, wick moisture, and resist odor while staying impressively lightweight. A breathable merino mesh back panel increases airflow, while the classic racerback cut allows natural shoulder movement. With a dropped hem for added coverage and reflective graphics for low-light visibility, the Bella Merino Tank is dialed for sustained effort in demanding conditions.
