The FXR Men's Vapor Merino 1/4 Zip combines lightweight warmth, moisture management, and versatile layering performance for cold-weather activity. Built from a mid-weight 180gsm knit with 20% Merino and 80% performance polyester, it helps maintain warmth when wet while delivering fast-drying comfort. The contour fit enhances moisture wicking, while antibacterial and anti-static properties support comfortable extended wear. Tonal flat-lock seams create a smooth feel against the skin, and thumbhole cuffs help keep the sleeves securely in place. A longer body length reduces midriff exposure during movement and layering, while screen printed and woven label logos with Thermalweld accents complete the technical design.
