10 Best Tri Shorts Women 2025 in the United States

The SLS3 Tri Shorts for Women are designed specifically for triathletes looking for a slim, athletic fit that supports performance. Made from a stretchy Nylon and Spandex blend, these shorts offer a second-skin feel that moves with you. The fabric’s flexibility and flatlock seams enhance comfort and reduce irritation during long races. The chamois padding here is thinner than typical cycling shorts, which helps prevent chafing and dries quickly — ideal for the transition from cycling to running.

An elastic waistband with a drawstring ensures the shorts stay in place, while the engineered single-layer leg grippers prevent the fabric from riding up without creating tightness or the 'sausage leg' effect. These features make the shorts comfortable for all three triathlon stages. However, the fit is quite compressive and tighter than regular workout shorts, so checking the size chart before buying is important to avoid discomfort. The shorts do not include pockets, which might be a downside if you want to carry small items during training or races.

These tri shorts provide a solid balance of comfort, performance, and style, particularly for women who want a close fit without sacrificing mobility or comfort on race day.

The SLS3 Tri Shorts for Women are designed with an athletic, slim fit that compresses slightly to support muscles during triathlon activities. Made from a stretchy blend of nylon and spandex, they provide a snug fit that feels like a second skin, which helps with muscle support and movement. The elastic waistband with a drawstring helps keep the shorts securely in place, while the single-layer leg grippers prevent the shorts from riding up without feeling too tight or causing the 'sausage leg' effect some compression gear can have.

Comfort is a strong point here—the shorts have flatlock seams that reduce irritation and itchy feelings, and the legs are long enough to help stop chafing during running. The chamois padding is thinner than typical cycling shorts, which is good for preventing discomfort on the run and helps the shorts dry faster after swimming, but still offers enough cushioning for cycling segments. However, if you are used to thicker padding, you might notice the difference.

These tri shorts don’t have pockets, which some athletes might miss for carrying small items during training or races. Also, the shorts require hand washing, so care might be a bit more involved than regular sportswear. The product’s sizing runs tighter than casual leggings or yoga pants, so checking the size chart before buying is important to ensure a comfortable fit. They are best suited for women looking for performance-focused triathlon gear that balances comfort, style, and function without extra bulk, working well for swimming, biking, and running segments, especially for those who prefer lighter padding and a sleek, supportive fit.
