Iron Butt? Air Butt. Really. The individual interconnected cells adapt to your contours and distribute weight in a way regular seats and pads can’t. Creates reduced pressure points for greatly increased all-day riding comfort. The outer cover is a stretchable, breathable mesh cloth material, with a nonskid bottom base material. Designed to stay in place and not creep around during ‘active’ riding or on day-long rides, it simply lifts off when not needed. Also includes attachment loops for mounting and security. As far as seat cushions for long-distance endurance riding goes, this is state of the art, based on technology originally developed for the medical industry. Stay in the saddle longer with more comfort. The inner, air-adjustable, form-fitting cushion is manufactured from a durable polyurethane bladder. Designed for riders who need some help on occasional long rides, offers excellent comfort compared to other gel/foam/synthetic options.
