The Patagonia Storm Shift Pant is built for active days on the mountain where the pitch changes, the effort spikes, and the weather does what it wants. The mesh thigh vents open up airflow exactly when the climbing or traversing gets hard, and the integrated gaiters lock out snow at the boot interface so the system holds together from first chair to last. What Our Gearhead(R) Experts Are Saying:"On high-output resort days the mesh thigh vents make a real difference. I can dump heat on a long traverse without stopping to strip a layer, and the fully sealed seams and GORE-TEX ePE shell keep me dry even when the storm catches up with me on the lift."
