The high-performance and technically tailored shell material of the Aether Men's Ridge Pants makes it the winter gear to get you through every season with wind and waterproof Toray Dermizax® 3L fabric that's durable and dependable while remaining breathable the whole time. Fully sealed at the seams and lined with recycled micro ripstop, these shell pants use Primaloft® insulation at the seat and front thighs for needed warmth in winter weather. The gusseted crotch lets you move around without restriction, while the on-seam thigh vents provide easy air-flow to cool you down when things heat up.
