A clever developer t-shirt inspired by the iconic “System of a Down” reference, reimagined for software engineers, programmers, DevOps professionals, SREs, and IT workers. The “System of a Dev” design connects coding culture, tech humor, backend development, infrastructure, Linux, Git, Docker, Kubernetes, and the daily life of people who build, deploy, debug, and maintain software systems. A strong gift idea for developers who enjoy programming jokes, rock-inspired designs, and geek apparel with personality. This t-shirt is everything you've dreamed of and more. It feels soft and lightweight, with the right amount of stretch. It's comfortable and flattering for all. • 100% combed and ring-spun cotton (Heather colors contain polyester) • Fabric weight: 4.2 oz./yd.² (142 g/m²) • Pre-shrunk fabric • Side-seamed construction • Shoulder-to-shoulder taping • Blank product sourced from Nicaragua, Mexico, Honduras, or the US Disclaimer: The fabric is slightly sheer and may appear see-through, especially in lighter colors or under certain lighting conditions.
