C-IN2 Undertone Jockstrap
The C-IN2 Undertone Jockstrap comes in ten two-tone colors, from Gains Green to Yale Yellow. Each shade is made by plating two cotton yarns of different colors into one fabric. The result is a soft, dimensional tone that shifts with the light instead of a flat print. Colors also include Benn Blue, Bower Blue, Bronsis Blue, Owen Orange, Patricio Purple, Prescot Pink, Princeton Pink and Ryan Red. Want it in black? Newsprint Black sits on its own Undertone Jockstrap listing. The jock sits low, below the natural waistline, with an open back framed by exposed elastic leg straps. Up front, a 1-ply contour pouch gives sculpted support and natural definition. The ultra-soft cotton feels light, smooth and breathable against the skin. A 1.5-inch monochrome elastic waistband carries tonal C-IN2 branding for a clean finish. Wear it to the gym, under jeans, or on its own when you want to be seen.
