Designed for cold-weather enthusiasts, the Patagonia Men's R1® Thermal Bottoms offer exceptional protection against the elements, making them the perfect companion for alpine expeditions and cold-weather fishing trips. Built with 91% recycled polyester and Technostretch fleece, these thermal pants are both environmentally conscious and highly functional, ensuring you stay warm, dry, and comfortable in the harshest conditions.
The soft microgrid fleece backing wicks moisture away from your skin, while the durable outer fabric repels wind and light snow, ensuring you remain insulated and protected. The ultra-stretchy fabric allows for unrestricted movement, whether you’re climbing mountains or casting lines in chilly rivers.
Designed with a low-profile adjustable waistband, these bottoms offer a snug, customizable fit that layers comfortably under waders or other outerwear. The tapered legs improve visibility and ease of layering, while two zippered handwarmer pockets securely store small essentials like keys, fly boxes, or hand warmers.
Whether you’re gearing up for a fly fishing expedition in the rivers of Europe or prepping for a cold mountain hike, the Patagonia R1® Thermal Bottoms provide the warmth and performance you need, combined with eco-friendly materials and thoughtful design.
