Mid-weight merino base layer pants with moisture-wicking performance, rapid drying, and low-bulk tapered ankles.

Built for cold-weather layering, the FXR Men’s Tenacious Merino Pants combine premium merino performance with a streamlined, next-to-skin fit. The mid-weight 200gsm knit uses 80% merino content to provide dependable warmth, including when wet, while the contoured fit helps move moisture away from the skin and supports rapid drying during active riding. With a maximum warmth rating of 2, they add lightweight insulation without unnecessary bulk.

Natural antibacterial and anti-odor properties help keep the fabric fresher through extended wear, while anti-pill and anti-static performance supports long-term comfort. Tonal flat-lock seams create a smooth feel under outer layers, and tapered ankles reduce bunching inside riding pants and boots. A jacquard elastic waistband and front fly opening complete the functional cold-weather design.
