These shorts feature the MK TRI2.0 MULTI DENSITY CHAMOIS for enhanced comfort and performance, specifically designed to support the aero position on the bike and comfort during the run.

The shorts also come with accessible storage pockets on each side, providing easy access to nutrition during activities.

The ultra-thin and ultra-light elastic leg grippers ensure a snug fit without discomfort from silicone, making them ideal for extended wear. Additionally, the flat locked stitching minimizes chafing and follows the body's contours, enhancing comfort and durability. However, the requirement to hand wash the shorts might be seen as slightly inconvenient for those looking for low-maintenance gear. Despite this, the MY KILOMETRE Men's Triathlon Shorts offer a combination of comfort, functionality, and durability that makes them a strong choice for triathletes, especially those participating in longer events.

They require hand washing, which could be a bit inconvenient for those used to machine-washable sportswear.

The chamois padding is foam-cushioned, giving you essential support during cycling while remaining light enough for running. However, some users might find the pad to be slightly too light for extremely long bike rides.

The fit is designed to stay in place, thanks to a waistband with a drawstring and soft leg grippers that prevent the shorts from riding up. The flatlock seams reduce chafing, adding to the comfort during a race. The presence of two open hip pockets is a thoughtful addition, making it easy to access energy gels and other small items on the go.
