What Our Gearhead(R) Experts Are Saying: "These are my go-to trekking pants for long mixed-terrain days. They're super breathable, stretchy in all the right ways, and the articulation makes a huge difference on steep steps or scrambles. The zippered cuffs are clutch when I'm wearing bulkier boots, and the pocket layout keeps everything secure." We reach for the Patagonia Terravia Trail Pant when long trails, shifting weather, and varied terrain call for reliable comfort all year long. Built from a lightweight recycled polyester-spandex dobby fabric, these pants deliver breathable four-way stretch and a slim, mobile fit that moves naturally through steep switchbacks, rocky traverses, and fast-paced day hikes. A PFAS-free DWR finish sheds light moisture when clouds roll in, keeping us protected without sacrificing comfort. Patagonia equips the Terravia with a thoughtful storage system-two zippered front pockets, a secure thigh pocket with mesh drainage, and dual back pockets for essentials we want close at hand. A straight-panel gusset and articulated legs enhance freedom of movement, while zippered cuffs with internal gussets fit easily over hiking boots. Made in a Fair Trade Certified(TM) factory with bluesign(R) approved fabric, these pants deliver durability, performance, and responsible design for every season on the trail.
