  Our company (Sky) needed some running clothes for our annual DHL Race in August, so i contacted 42K and told them about our situation. We needed 50 sets of t-shirts/shorts with specific design requirements to match our logo and branding, a design beyond what was available on the website. With the help from Luis, we found a design together that looked incredible, they also sent us generic t-shirts and shorts for us to try out and decide what sizes we wanted before making an order. We're so happy with the professionalism and good communication that 42K Running provided, and we will definitely use them again next time we need custom clothes.
