Extreme cold environments are usually dry and sunny. Wind resistance and insulation are generally a higher priority than protection from rain. Depending on whether your activity is more static or active, high-loft layers like an L7 may be required.
I’ve tested these pants in the field during winter with rain and snow. These pants were fantastic. Kept me dry and comfortable but also breathable enough to not make me sweat when active.
Great quality! Fits perfect.
I'm 5'7 205 wear 36 and waist fit fine but the regular is too long. I should get size short. I can adjust knee fine. A9-T mission pant are excellent quality at great price!
Great looking jacket, seems well made
