Brushed microfleece thermal base layer with fast-drying performance, athletic fit, and thumbhole cuffs.

The FXR Men's Pyro Thermal Longsleeve delivers lightweight warmth and comfortable cold-weather layering with a soft 180gsm brushed microfleece construction. A polyester / spandex blend provides stretch and comfort, while synthetic yarns help repel water and dry rapidly during active use. The athletic fit enhances moisture wicking and keeps the layer close to the body for efficient performance under outerwear. Tonal flat-lock seams create a smooth, streamlined feel against the skin, while thumbhole cuffs help keep the sleeves securely in place. A longer body length helps reduce midriff exposure during movement, and debossed and woven label logos complete the design.
