Wear your coffee. Don’t just drink it. The Men’s Sigmatech Shirt is infused with repurposed coffee grounds, transforming one of the world’s most consumed beverages into a high-performance men’s gym shirt. 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, men’s athletic shirt designed for serious training. This fitness top isn’t just about sustainability; it’s built to perform, offering natural moisture-wicking, odor-resistant, and 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 shirt packed with performance benefits.
The coffee-infused yarn enhances breathability, speeds up drying time, and naturally neutralizes odors. Plus, SILVADUR™ silver ion technology amplifies the fabric’s antibacterial properties, so you stay fresher for even longer. Coffee’s natural UV-blocking properties offer sun protection, while its anti-static benefits keep the fabric from clinging. And because the coffee-infused microcapsules are embedded in the fibers — not just a surface treatment — the odor-fighting and moisture-wicking properties last wash after wash. The four-way stretch construction moves with you, while flatlock seams prevent chafing, making this the ultimate exercise tee for lifting, HIIT, running, and beyond. The Sigmatech T-shirt was designed with a sleek athletic cut to flatter your arms and shoulders -- proof that the best innovation doesn’t just feel good — it performs, too.
Coffee-infused polyester is a rare and innovative fabric, blending sustainability with high-performance benefits — so if you want a men’s gym shirt that’s as unique as it is functional, the Sigmatech Shirt is made for you. Available in various colors and sizes S-3XL.
