Men's Sigmatech Tank

Wear your coffee. Don’t just drink it. The Men’s Sigmatech Tank Top is infused with repurposed coffee grounds, transforming one of the world’s most consumed beverages into a high-performance men’s gym tank top. Every year, more than 23 million tons of coffee waste are discarded, but instead of letting those grounds go to landfills, we’re turning them into something better: an innovative performance tank top designed for serious training. This shirt isn’t just about sustainability; it’s built for fitness, offering natural moisture-wicking, odor-resistant, and is sleeveless for breathable comfort for every workout. Using a cutting-edge process, coffee grounds are carbonized at over 1,400°F, ground into nanoscale powder, and blended with recycled polyester to create a men’s workout tank packed with performance benefits. 

• Sustainable Performance Fabric – Made with 49% coffee polyester, reducing landfill waste and lowering carbon emissions. Coffee is sourced from discarded grounds from coffee roasters in Taiwan.
