Inside Trail Racing (ITR), Northern California’s premier trail-running event company, announced today their partnership with compression outfitters, OS1st. For all of 2018, ITR will be issuing OS1st compression socks and sleeves as awards and giveaways at each event; base-layer compression gear will be used by members of the ITR racing team. The union will provide a valuable and propitious platform for both companies and their customers, as they can expand their reach, introduce new experiences, and better support participants in the athletic world.

As culture and technology continue to shift and advance at rapid paces, companies have a duty not only to cater to the needs of the customers, but also to help clarify or produce healthy goals. This partnership will positively sculpt the performance and mission of the user by accelerating the time it takes to recover from hard workouts or injuries, and using new-found fitness to put to the test on the trails.
