These versatile mountain running shorts feature a redesigned crotch and forward-shifted side slits to minimize stress during leg lifts, allowing for smoother leg movement. The material is a lightweight and abrasion-resistant nylon softshell. Large-capacity mesh pockets are located on both sides of the hips. I've used these for trail running and running for several years, and they've proven to be highly durable with no noticeable damage. Measurements (laid flat): Waist: 35cm Length: 41cm
