We at Flatline Supply Co. were founded by two best friends who started their careers side by side in EMS. Built on late nights, long shifts, and the bond of serving others, our brand is dedicated to honoring first responders, veterans, and everyday heroes who give everything for their communities. Our designs reflect the grit, sacrifice, and resilience it takes to answer the call, while shining a light on the importance of mental health and the fight against PTSD.

Flatline Supply Co. is more than a company. It is a community of brothers and sisters who know the weight of the job and the value of standing together. Join us in supporting those who run toward chaos, in starting honest conversations about mental wellness, and in proudly representing the calling that defines us.

Answer the call. Honor the fallen. Support the living. Welcome to Flatline Supply Co.
