They contain a comfortable elastic waistband, Ipod/phone pocket on one side and Delfin Spa logo on the other. Leg openings with velco closure for greater comfort/fit. Bio Ceramic material in these capris both generates Far Infrared Rays (FIR) and reflects your body's own FAR infrared rays. "FAR" relates to the size of the wavelength and Infrared is the part of the light spectrum that generates heat. The primary benefit of these rays is to help to break down cellulite cells, improve circulation and revitalize tissue. Increased heat and molecular stimulation enhances the effectiveness of exercise, increases blood flow, and accelerates metabolism to burn more calories. Bio Ceramic capris also improve the effectiveness of anti-cellulite cream by assisting its penetration deep into skin layers. Capris are a great option to wear during aerobics, yoga or any other exercise activity. Bio Ceramic capris feature 1.5mm neoprene with soft nylon lining.
