The HugFit waist is made of a perforated double elastic to make sure there isn't any pressure on your belly, even when bloating happens during the run. Two extra angled back pockets offer plenty of storage for bars and gels while preventing any loss during the race thanks to a tight elastic opening. Fill the ice pockets located near the common iliac artery with ice from the feed zone to help blood vessels stay cool. The new Tri Air 2 chamois offers more padding in the front area for maximum comfort when riding in aero position .
