We've been with the Holly for a few years now and our love is stronger than ever. She's a merino/poly blend for a mix of odor resistance and strength with mesh paneling along the sides for breathability. The Holly has a loose fit, with ample room for elbow pads and other body protection, but with a clean silhouette for more casual pedaling. The Holly, like all tops in the Wild Rye line, is designed for versatility with minimal branding to take you from cool fall pedals to warm bike park days... to hiking, trail running, you name it.
