We took the premium sound, patented optics and all-day comfort of THUMP 2 and engineered them in a completely new architecture. This sport design is even more lightweight, and it adds the durability of sweat resistance and the convenience of interchangeable lenses. THUMP PRO launches a new era in sport training.Coaches and trainers know that athletes have one-track minds — at any given moment, the human brain is focused on a single thing. Divert attention from the burn of exertion and your training will find a whole new level. That’s why we invented THUMP PRO, digital music eyewear in a sport design that fuels your training session with the music that moves you. Whether you’re running, biking or pushing your potential with any kind of workout, THUMP PRO will help you find your limits and just as easily ignore them.
