The Patagonia Men&';s Dirt Craft Bike Shorts are built to handle everything from all-day trail rides to quick after-work laps, delivering the durability, comfort, and versatility mountain bikers demand. Designed as a true singletrack workhorse, these shorts combine rugged construction with rider-focused features, making them an excellent choice for everything from technical descents to long backcountry adventures. The overshorts are constructed from a breathable and highly durable four-way stretch fabric made with 82% recycled polyester sourced from coastal communities at risk of plastic pollution and 18% XLANCE plain weave. This performance-oriented material moves naturally with the rider while providing the toughness needed to withstand repeated trail abuse. A PFAS-free durable water repellent finish sheds light moisture, mud, and trail spray to help keep riders comfortable in changing conditions. Included with the shorts is a removable padded liner featuring a contoured chamois and highly breathable mesh panels. The liner delivers all-day support and moisture management, while the removable design allows riders to customize their setup based on the day&';s ride. A low-profile external hook-and-webbing waist adjustment system provides a secure, personalized fit without creating pressure points under a hydration pack or hip belt. Multiple storage options include two front drop-in pockets and two zippered thigh pockets positioned for easy access while seated in the saddle, ensuring essentials remain secure and within reach. The 12A 1/2-inch inseam is specifically designed for mountain biking, providing additional coverage while comfortably overlapping with most knee pads. Built using bluesign approved materials and manufactured in a Fair Trade Certified factory, the Dirt Craft Bike Shorts combine trail-ready performance with Patagonia&';s commitment to responsible manufacturing.
