GET ENERGIZED & EXTEND WORKOUTS! Our HIGH WAIST Shorts are NOT your standard “exercise shorts”. They feature Bio-Energy Technology and integrate innovative performance fabrics. Various health promoting minerals combined with technology is what sets us apart from other brands. Discover the difference with DELFIN!We listened to feedback and improved this collection! For our past customers, you may have noticed we switched to a Single fabric layer from our previous 2-layer design (Opaque; not see thru or sheer). You’ll love the wider waistband for a more flattering look (without losing tummy coverage) and a smaller gusset for better fit & comfort.HOW DO THEY WORK? A range of minerals are embedded in the dolphin ink pattern (on the inside). When in contact with skin, your body heat “activates" the minerals and they offer multiple benefits including: Improved micro-vascular flow, muscle stimulation & reduced muscle fatigue to help prolong your workouts!THE SCIENTIFIC PART: The key is the scientifically patented mineral formula, which includes: oxidized silicon, magnesium, alumina and calcium. When thermally activated, it creates vibration at the atomic level, resulting in ENERGY, which is transmitted to the body. Proven benefits: Increased Micro-Circulation - achieved through inhibition of Rouleaux formation in the blood and Energy Enhancement - achieved through increased oxygen rate and skin cell vitality.PLEASE REFER TO PHOTO OF SIZE CHART FOR ACCURATE SIZE GUIDELINE (do not click blue size chart link).
