What Our Gearhead(R) Experts Are Saying: "This baselayer has become my go-to for rides in every season. The merino mesh keeps me cool when I'm working hard, warm when I'm descending, and it never feels clammy. The fit is slim but not restrictive, and the flatlock seams mean zero chafing." The Velocio Merino Mesh Sleeveless Baselayer delivers year-round performance in a minimalist package. Crafted from an ultrafine merino wool and polyester blend, it harnesses the natural thermoregulating and odor-resistant qualities of merino while adding polyester for improved durability and moisture management. The result is a lightweight, breathable layer that keeps us comfortable through long climbs, fast descents, and everything in between. Cut slim without being restrictive, this baselayer layers seamlessly under jerseys or outerwear. Flatlock stitching eliminates chafing on long rides, while the crew collar and tagless neckline provide a smooth, distraction-free fit. Whether it's peak summer or the shoulder seasons, the Merino Mesh Sleeveless Baselayer works hard to keep our temperature just right.
