10 Best Triathlon Shorts 2026 in the United States

The MY KILOMETRE Mens Triathlon Shorts are designed with triathletes in mind, especially those doing long-distance races. The fabric blend of regenerated polyamide and spandex offers a good balance of stretch, durability, and chlorine resistance, making these shorts suitable for swim-bike-run transitions, including indoor pool swims. The UPF 50+ protection is an added bonus for outdoor training or events.

The padding, labeled as MK TRI 2.0 multi-density chamois, is tailored for the aero position seen in cycling and also provides comfort during the run. This means you get a cushion that supports long rides but doesn't bulk up, helping reduce discomfort. Fit-wise, the adjustable drawstring ensures you can customize the waist tightness, and the ultra-thin elastic leg grippers hold the shorts in place without causing the usual silicone grip irritation, which is common in many cycling shorts.

Practicality is enhanced by nutrition storage pockets on each side of the legs. These easy-access pockets allow you to grab gels or snacks quickly while on the bike or running, a feature triathletes find very useful. The flat locked stitching helps reduce chafing by following your body’s shape and adds strength to the shorts. One drawback might be the care instructions, as they require hand washing, which might be inconvenient for some users. Also, the product is imported, so sizing could vary slightly compared to domestic brands. These shorts provide solid performance features for triathletes seeking comfort, practical storage, and durability, especially benefiting those who prioritize swim resistance and sun protection during their training or races.

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.

The Zoot Women’s Core 6-Inch Tri Shorts are designed with triathletes in mind, combining comfort, support, and performance. Made from premium Italian fabric, these shorts excel in quick-drying and moisture-wicking, which is key for triathlon events involving swimming, biking, and running. They offer UPF 50+ sun protection, a valuable feature for outdoor long-distance training or races. The ultra-plush chamois padding provides good cushioning for the bike leg without causing discomfort during the run or swim, striking a nice balance that many triathlon shorts struggle to achieve.

The fit is streamlined and athletic, with a mid-rise design that feels supportive but not restrictive. The leg grippers use a non-elastic material to stay put without the tight squeeze that can sometimes cut off circulation or cause irritation. Dual hip pockets are handy for carrying small essentials or nutrition, which is a practical touch for longer sessions. Additionally, the Seamlink stitching minimizes chafing by moving with your body, enhancing comfort during all triathlon disciplines.

While the shorts are performance-driven, their minimalist style means they might lack extra features that some athletes prefer. The athletic fit may not suit those seeking a looser or more relaxed cut. These tri shorts are well-suited for women looking for a durable, well-padded, and quick-drying option with useful storage and sun protection, especially ideal for race day and tough training.
