Men's Calvin Klein JOCKSY Jocksy Calvin Klein are a very interesting model. At the waist there is a wide and comfortable woven elastic. Around the buttocks are two more rubbers. So no cord cut in the butt, as is the case with thongs. They look almost like a jockstrap, but beware, they do not protect against impact. This model is simply comfortable, moreover, it fits perfectly. Jocks are packed in an original gift box. - Rubber - woven- Material - cotton- Composition - 95% cotton, 5% elastane- Washing - 30°C- Dryer - no- Ironing - yesSize chart CALVIN KLEIN - MEN BOXERS / BRIEFS SIZE HIP CIRCUMFERENCE (CM) UNSTRETCHED (CM) S 68-77 32.5 M 78-87 35.5 L 88-98 40 XL 99-114 42.5 XXL 115-120 46
