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.
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 training tank for lifting, HIIT, running, and beyond. This top features a traditional, athletic cut, but it's higher performance than your typical cotton blend T-shirt -- 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 workout tank that’s as unique as it is functional, the Sigmatech Tank Top is made for you. Available in various colors and sizes S-3XL.
