I?ve got a drawcord to keep me locked in position and a wide elastic leg opening and waistband for added comfort around your hips and legs. Compared to my other trunk friends, I?m a skinny runt but still very comfortable to have around and I?ll go the distance to be with you as long as you keep swimming. Made from our exclusive C-Infinity fabric, a 100% Italian polyester that is a colourful breakthrough in chlorine resistant fabric technology! The superior choice for swimmers, C-Infinity has exceptional strength and can retain its durability far beyond other elastane swimwear fabrics. Ideal for frequent pool use for recreational and performance-based swimming.
