trisuits

A trisuit is a one-piece garment designed for triathlon that is worn across all three disciplines: swimming, cycling, and running. It is intended to provide a streamlined fit, quick drying, and convenient transition between segments, allowing athletes to minimize changes of gear.

Construction and materials vary, but most trisuits use synthetic blends such as nylon or polyester with elastane (spandex) for stretch. Fabrics are chosen for moisture wicking, breathability, and chlorine resistance. The suit commonly features flatlock or other low-friction seams to reduce chafing, and a zipper option (front or back) to aid on/off and ventilation. Leg and sleeve lengths come in multiple options, including sleeveless, short-sleeve, or long-sleeve designs, and leg lengths ranging from short shorts to knee-length or longer.

Padding in a trisuit is typically minimal or absent compared with dedicated cycling shorts, since the suit is designed to transition quickly from swimming to cycling and running. Some models include a light, interior chamois or a slim pad to provide brief comfort on the bike without absorbing water during swimming or causing excess drag.

Features may include a rear pocket or small waist pockets in some designs for nutrition or small items, though pockets are less common in racing models due to drag concerns. Sizes and fits emphasize a snug, compressive feel to reduce water resistance and provide support during high-mpeed activities.

Care typically involves rinsing after swimming, avoiding fabric softeners, and air-drying. Trisuits are popular with competitive triathletes and fitness enthusiasts seeking a single, efficient garment for training and race-day use.
