10 Best Tri Shorts 2025 in the United States

The MY KILOMETRE Men's Triathlon Shorts are designed with a blend of 78% Regenerated Polyamide and 22% Xtra Life Lycra fibre, which makes them durable and chlorine resistant, suitable for both pool swims and outdoor use with UPF 50+ protection. The moderate compression helps with muscle support during long-distance races.

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 chamois padding is a significant strength, as it balances cushioning and flexibility well for long-distance triathlons. 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.

The SLS3 Triathlon Shorts for men provide a mix of comfort and performance, making them suitable for racing. They are made from a blend of 80% nylon and 20% spandex, offering a balance of flexibility and durability. The material ensures strong muscle support without being overly tight, which is great for long races. 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. The shorts are designed by athletes, which shows in their functionality and user-friendly design.

On the downside, the requirement for hand washing may be seen as a disadvantage for those looking for easier care options. Additionally, the shorts are made in China, which may be a consideration for those who prefer locally-made products. If you're looking for affordable, high-quality triathlon shorts that cover all the essential features without breaking the bank, these shorts are a solid choice.

The shorts include a foam-padded chamois that provides cushioning for the bike portion of your race while remaining slim enough to not slow you down during the run.

Two open hip pockets provide practical storage for energy gels or snacks, allowing easy access on the go. The flatlock seam construction helps prevent chafing, and soft leg grippers keep the shorts in place so you won’t have to stop and adjust them mid-race. These shorts require hand washing, which might be less convenient if you prefer machine care. While the foam padding works well for most riders, it may not offer the same level of protection as thicker cycling-specific pads for very long rides.

These shorts deliver solid comfort, practical features, and a reliable fit at a reasonable price, making them especially suitable for triathletes looking for straightforward gear made by a brand with experience in the sport.
