Tracksmith Strata Singlet is the lightest and most technical racing singlet, built to perform when results matter most.

Originally developed for the athletes in our Amateur Support Program competing at the 2020 Olympic Marathon Trials, the Strata Singlet has evolved to push the boundaries of performance ever since. Made of a super lightweight and highly technical Swiss fabric, the Strata Singlet is trusted by world class athletes in their biggest races from the 100m dash to the Marathon. Whether you’re chasing the podium or a personal best, our Strata Singlet is meticulously crafted for your most important days.

Product Highlights

• The lightest singlet is treated with coldblack®, an innovative technology that blocks UV rays to prevent heat absorption in the fabric. This keeps you cooler for longer - perfect for your hardest efforts or the hottest days.
• The Strata Singlet uses our most advanced fabric to date. It’s silky-soft and feather-light, with an internal grid structure that rapidly wicks moisture away from the skin.
• The coldblack® technology prevents the fabric from absorbing heat, keeping a black garment as cool as a white one. No matter how hot the pace or the temperature, the Strata Singlet performs when results matter most.
