"Men's Brooks® Source Tight: The Men's Brooks Source Tight is a lightweight running tight built for runners who want coverage and compression without anything getting in the way. The fit is secure but not restrictive, with a flat waistband and adjustable drawstring that stays put whether you're grinding through a tempo run or logging easy miles. Two drop-in pockets keep your essentials accessible so you can focus on the run.The Source Tight is constructed with DriLayer® HorsePower fabric - a 78% polyester/22% spandex blend that moves with you and manages moisture during harder efforts. No side seams means less chafing and a cleaner, lighter feel against the skin. The compression level is dialed in to feel supportive without being overly tight, and the minimal seaming throughout keeps the fit smooth from start to finish. These tights are also made with bluesign®-certified materials, so the performance comes with a lower environmental footprint.Why Our Fit Experts Love It""I've worn a lot of running tights and the thing I noticed right away with the Source Tight is how clean the fit feels - no bunching, no seams rubbing on longer runs. The flat waistband actually stays flat, which sounds simple but makes a real difference when you're an hour into a run. The pockets are easy to access without breaking stride."" - Dave, Road Runner Sports Fit Expert, San Diego, CAWho It's Best ForThe Source Tight is a strong choice for male runners who want a reliable, low-distraction tight for training runs of any distance.
