To protect our legs from the trail's thorny brush and the summit's mist without suffocating our microclimate, we pull on the Patagonia Quandary Jogger. The ultralight material lets passing breezes blow through and moves our sweat away, keeping us comfortably cool as it fights off rugged terrain, beads up drizzles, and absorbs crisping rays, shielding our legs from unsavory conditions, so we get nothing but the enjoyment.
