Our Jagger Muscle Tank in dark grey is the perfect sleeveless muscle tank for all year round, cut with a higher arm hole to be worn alone or under jackets and blazers. The 1X1 rib neckband makes this a classic—yet it still feels modern, casual, and cool in its silhouette. Our Jersey Knit offers a luxurious comfort that is unrivaled—knitted with both S-twist and Z-twist yarn to sustain longevity and stability, preventing unnecessary twisting and torquing. During the production process, the S-twist yarn is spun counter-clockwise creating a right-handed twill. The Z-twist yarn works in opposition, spinning clockwise for a left-handed twill. This opposition—when working together—yields a softer, more durable fabrication and gives strength to the yarn making it more difficult to pull apart. Designed in 100% Cotton
