10 Best Triathlon Shorts 2025 in the United States

The Zoot Men’s Core 7-Inch Tri Shorts are designed with triathletes in mind, balancing speed, comfort, and practicality. The premium Italian fabric is lightweight, quick-drying, and offers UPF 50+ sun protection, which is great for long outdoor workouts or races. The fit is streamlined and athletic, with a mid-rise and a pull-on style that should suit most body types comfortably. One standout feature is the ultra-plush chamois, which provides good padding for cycling without causing discomfort during swimming or running phases. This makes transitions smoother and helps reduce irritation.

The leg grippers use a non-restrictive design, so the shorts stay in place without the tight squeeze some elastic bands cause. For carrying essentials, dual hip pockets offer race-ready storage, allowing easy access to nutrition or small items. The seam construction uses a chafe-free stitching method, which is important to avoid skin irritation during long sessions. Some may find the fitted cut too snug if they prefer a looser fit, and the 7-inch inseam might not provide the desired coverage for all users. Additionally, while the pockets are useful, they are relatively small and may not accommodate larger items.

These shorts are well suited for triathletes seeking a reliable, performance-focused option that supports endurance and speed without sacrificing comfort.

The SLS3 Triathlon Shorts are designed with triathletes in mind, offering a good blend of comfort, support, and practical features. Made from 80% nylon and 20% spandex, this fabric mix ensures a stretchy yet durable fit, which helps with muscle compression and freedom of movement. The medium compression provides decent muscle support without feeling too tight. The shorts include a foam-cushioned chamois pad tailored for both cycling and running, offering protection during your bike ride while being slim enough not to slow you down on the run. Flatlock seams reduce irritation and chafing, enhancing comfort during long sessions.

The 8-inch inseam with soft leg grippers helps keep the shorts in place, so you won't need to stop and adjust them mid-race. Two open hip pockets are practical for holding energy gels or small snacks, giving easy access on the go. The waistband includes a drawstring for a customizable fit, though it might require occasional tightening. One minor downside is that the shorts are hand-wash only, which could be less convenient if you train frequently. While the material is premium and feels nice on the skin, the imported nature and sizing should be checked carefully before buying.

These shorts are well suited for triathletes looking for a reliable, no-frills option that balances performance and price without unnecessary extras.

The MY KILOMETRE Triathlon Shorts are designed for athletes seeking performance and comfort in long-distance races. The main fabric is a blend of 78% Regenerated Polyamide and 22% Xtra Life Lycra, which offers moderate compression, chlorine resistance, and UPF 50+ protection. These features make the shorts suitable for both indoor pool swims and outdoor activities.

The inclusion of accessible nutrition storage pockets on the sides of the legs is a thoughtful addition for easy access during bike rides or runs, enhancing convenience for athletes. The MK TRI2.0 MULTI DENSITY CHAMOIS is specifically designed to provide comfort in the aero position, which is crucial for long cycling sessions and transitions to running. This padding aims to maximize performance without compromising comfort.

The ultra-thin and ultra-light elastic leg grippers ensure a snug fit without causing silicone discomfort, adding to the comfort and flexibility of the shorts. Flat locked stitching is used to prevent chaffing and enhance durability, benefiting those who engage in rigorous activities. However, the shorts require hand washing, which might be inconvenient for some users. Additionally, the drawstring closure might not be preferred by everyone, as some might find it less secure compared to other closure types. Despite these minor drawbacks, the MY KILOMETRE Triathlon Shorts are a strong contender for triathletes looking for reliable, comfortable, and performance-oriented gear.
