Mockup Arena was a project I developed after realizing the gap in available templates and mockups for sports fans (and subsequent need for this kind of product). With the help of the design community, I was able to launch Mockup Arena in February of 2016 with around 30 templates and mockups. Since then, the library has grown to nearly 50 templates, all premium in quality.
The files are still available for free download to anyone for personal use (see below). The project has seen immense response and praise, with total downloads over the life of the site surpassing 31,000. The long-term goal of this site was to help aspiring sports designers show their work and learn the skills necessary to develop a career in the sports and/or design industries.
