The NSi Story

My name is Tony Calimano, and I am the founder of NSi (NEVER STAY idle). My partners—Greg Keagle, a former MLB player for the Detroit Tigers, and Aaron Kokal, President and CEO of Drive Results—have joined NSi to help us become the future of sports performance apparel by offering a natural fabric apparel solution.  NSi was founded on one core principle: Accountability.

We believe that the time we allow to pass will never come again. Time is unique; once it is gone, you can never reclaim it to take action. When I was a teenager, my mother would often tell me in Spanish,"Hace algo util", which translated to me, "NEVER STAY idle". Action is the antidote to stagnation. By refusing to stay idle, you transform potential into progress, build unstoppable momentum, and outpace the competition. Every small, consistent step forward compounds over time, ensuring continuous growth and adaptation while turning your most ambitious goals into reality.

Our goal at NSi is to build the activewear brand that physically alters how our fabric interacts with sweat while carrying a distinct creed of accountability, you must bridge advanced textile science with deliberate, high-impact apparel design. Starting now, you have the opportunity to embody the NSi creed. Experience the peak of performance by wearing the first of its kind in natural athletic apparel.
