Meet the Luka: our lightest, most breathable short. Built for cardio days, speed training or as the perfect comfortable option for relaxing after your workout, the Luka has been our best-selling style since it was introduced. When we created the Luka, we focused on freedom of movement and comfort. Our split-curve hem, 4-way stretch fabric and laser-perf ventilation are just a few of the reasons you'll come back for more. NOTE: the optional built-in liner is not compression.
