Designed for training, the Tracksmith Brighton Base Layer has an engineered Merino mesh construction with a closed knit on the sleeves for added protection. The idea came from a fishnet shirt with regular sleeves worn by legendary marathoner "Boston Billy" Rogers.

Wear it alone or under a mid-layer or jacket. The Merino material is both soft and moisture-wicking with natural temperature regulation properties. Plus, it has the added benefit of being odor-resistant.

Working with industry leading manufacturers in Europe, Tracksmith produced the Brighton in a seamless knit construction to reduce friction. The result is a piece that combines the comfort of pyjamas with unbeatable performance.
