Our warmest Rho base layer pant combines Fortius Air 20 nylon and Coreloft Compact synthetic insulation with Torrent microfleece panels at the lower leg, waistband, and crotch gusset to deliver a high level of thermal performance without bulk. The next-to-skin fit layers easily, and articulated patterning combines with stretch for freedom on climbs, uptracks, and descents.
Updated with two exterior drop pockets and stretch Coreloft™ insulation for improved freedom of movement, revised seam placement at the knee and inner calf to reduce chafing, and a next-to-skin fit for comfort under outer layers.
