French-Swedish design duo Claus Lindorff and Jérome Touron are the master minds behind the Ron Dorff line that is known to produce simple solid basics for men. The Swim side of Ron Dorff are their SwimGym shorts. The drawstring elastic waistband and open-leg cut make this an ideal for long workout sessions. This in part to the tight woven, microdenier polyester pulls moisture away from the skin without chafing. Made for active wear, great for swimming as they do for a run or jog while looking good getting your sweat on with the ease of quick dry fabrics with personal favourite of mine the solid black and blue Ron Dorff shorts summer appropriate.
