Under Armour Men's Mod Grey Medium Heather/ Black Athletic 20 T-Shirt

The Under Armour Men's Athletic 20 T-Shirt in Mod Grey Medium Heather/ Black is a versatile, understated option that works across a wide range of contexts. The medium heather Grey body has a slightly textured, multi-dimensional appearance that reads as more refined than a flat-dyed solid, giving this colorway a casual- feel that works whether you are at the gym, on a job site, or out running errands.

Paired with the Black raglan sleeves, the result is a clean two-tone look that feels contemporary without being trend-dependent. The 60% cotton, 40% polyester blend fabric delivers the soft, lived-in comfort that defines the Athletic 20 across all colorways.

Cotton keeps the fabric breathable and against the skin, while polyester contributes durability and shape retention. Heather fabrics in this blend tend to be particularly soft because the yarn itself is blended before being knit, creating a fabric surface that is gentle and consistent.

The raglan sleeve construction runs diagonally from the neckline to the underarm, providing unrestricted range of motion and highlighting the Black sleeve contrast against the heather body. The fuller cut gives this tee a relaxed, fit that does not cling or restrict movement. The split hem at the bottom allows freedom of motion without disrupting the clean silhouette.

The heatseal UA logo at the chest is minimal and refined, sitting cleanly against the heather Grey background. For branded programs, the Mod Grey Medium Heather body accepts embroidery with excellent results. Color print also works on this base, though designers should account for the heather texture when selecting fine-detail graphics.
