The Mens Causey Pike Pants–Short from Patagonia are durable backpacking, trekking and/or hiking pants, made of 95% nylon, with 67% recycled content to lessen the environmental impact, and 5% spandex with four-way stretch. They provide 40-UPF sun protection and have a DWR (durable water repellent) finish to shed moisture. A gusseted crotch and articulated knees allow a full range of motion. Front pockets, a rear pocket and a side-leg bellowed pocket, all of which secure with zips, carry the load. Best for lean-to-medium builds, Causey Pike Pants have a slim-straight silhouette that sits on the waist with a regular rise, fits not too loose but not too tight in the seat and thighs, then stays straight from knee to ankle. Details include zipped bottom cuffs with expandable gussets to fit over boots, a cleanly finished fly and a waistband with a fully adjustable, integrated webbing belt that allows for a personalized fit.
