"Men's Nike® Dri-FIT Fast 3"" Brief-Lined Short: When you want to run fast and stay comfortable, these men's running shorts from Nike are built around that goal. The Dri-FIT Fast 3"" Brief-Lined Short features a 3"" inseam and a brief liner that keeps everything in place so you can focus on your pace. Nike Dri-FIT technology pulls sweat away from your skin and helps it evaporate quickly, keeping you dry during harder efforts. Side vents add airflow where you need it most.The body is made from perforated woven fabric that's lightweight and extra breathable - a noticeable difference when the temperature climbs or the effort picks up. An elastic waistband with a drawcord lets you dial in the fit before you head out. Two drop-in waist pockets are sewn into the liner so your key or card stays put without bouncing around mid-run. A reflective Swoosh logo adds low-light visibility for early morning or evening runs. Body is 100% polyester; the lining is 92% polyester and 8% spandex for a bit of stretch where it counts.Why Our Fit Experts Love It""I grabbed these for a tempo run on a warm afternoon and the perforated fabric made a real difference - I barely noticed I was wearing them. The liner pockets held my key without any movement, which is something I always notice on shorter inseam shorts. If you run in the heat and want something that stays out of your way, these are worth trying."" - Dave, Road Runner Sports Fit Expert, San Diego, CAWho It's Best ForThese shorts are a strong choice for men who prefer a shorter inseam and want a lightweight, breathable option for warm-weather runs, tempo workouts, or daily training. If you run in the heat and want moisture-wicking fabric, a secure liner, and a little storage without the bulk, the Dri-FIT Fast 3"" Brief-Lined Short fits that need well. Runners who like a snug, supportive feel from a brief liner rather than a looser short will appreciate the fit.
