Tri-BlendX™: Toughness and comfort don't have to be mutually exclusive. Our in-house blend includes an antimicrobial treatment, which means your shirt won't absorb whatever odors it may come up against. The result is a shirt that's tougher, lasts longer, and less likely to end up in a landfill somewhere. 18" LengthThese have no external branding aka "slick."
