The Gold Standard in Base Layers

Meet the best-selling Tracksmith Brighton Base Layer, made with an engineered Merino mesh that feels remarkably soft against the skin while working hard through every mile. Its moisture-wicking blend helps regulate temperature and stays virtually impervious to odor, so you can keep moving comfortably from the first warm-up to the final stretch.

Designed to slip easily under a mid-layer or jacket, the Brighton is also far too flattering to hide. Its seamless construction creates a smooth, easy fit that is not too tight to wear on its own, giving you one remarkably versatile layer for training, travel, and everyday comfort.

Engineered Merino mesh: Soft, breathable comfort with temperature-regulating performance.
Moisture-wicking blend: Helps move sweat away from the skin while you train.
Odor resistance: Stays fresh through long days and repeat wear.
Seamless construction: A smooth, flattering fit with no unnecessary bulk.
Layering versatility: Wear it under a jacket or mid-layer, or on its own.

It has the comfort of your favorite pajamas, with the performance to make it your most reliable training layer.
