Breathable enough for your run. Light enough for all-day wear. The Nike Run Division Pinnacle Shorts deliver a design created from athlete-informed data, courtesy of the Advanced Running Concepts (ARC) team. They use perforated details & smooth materials for support. The result is ventilated comfort, helping you stay dry through every mile. An elastic waistband with a drawcord lets you adjust the fit. The low-profile waistband helps reduce heat & friction while you run.
