10 Best Triathlon Shorts 2026 in the United States

The MY KILOMETRE Men's Triathlon Shorts are designed with features that suit long-distance triathletes well. Made from a durable blend of 80% polyamide and 20% Xtra Life Lycra, they offer medium stretch, muscle compression, and UPF 50+ sun protection, helping keep you comfortable and protected during outdoor training or races. The fabric is also chlorine-resistant, making these shorts suitable for swimming sessions in a pool. The fit is skinny and low-rise, with an adjustable drawstring to ensure they stay in place without being too tight. Leg grippers use a wide elastic band with silicone print, which effectively prevents the shorts from riding up during cycling or running, adding to comfort and stability.

A standout feature is the MK TRI 2.0 multi-density chamois padding, designed specifically for the aero cycling position, providing good comfort on the bike while not being bulky for running. Seam construction uses flat locked stitching that reduces chafing, which is important for long races. Storage is another strong point, with four easy-to-reach side pockets for nutrition or small essentials during transitions. However, care instructions require hand washing, which might be less convenient for some.

These shorts represent a solid choice for triathletes seeking a versatile, well-padded, and comfortable option with useful storage, especially if you want something that performs well across swimming, cycling, and running stages.

Made from a lightweight, medium-stretch fabric blend of nylon and spandex, they provide muscle support without feeling too tight. The shorts include a slim foam cushion (chamois) that is thin enough not to bother you when running but still protects during cycling, which is important for multi-sport comfort. Flatlock seams and a drawstring waistband help reduce chafing and ensure a secure fit. The leg hems have a soft finish that prevents the shorts from riding up, so you don’t have to keep adjusting them during your race.

For storage, there are two open hip pockets which are ideal for carrying energy gels or small snacks, though there are no zippered or secure pockets for valuables.
