Virus Apparel Intl . The rubber banded top originally found it's audience thru Virus who sold the compression tops to top MMA fighters, MX athletes, and Crossfit enthusiasts. Immediately we saw the benefit of the banded compression for art uses, so we went to Virus and started using these tops in our own art sessions and found them to help us feel better after a long day to slouching over a client or canvas. The X - Form is meant to be warn under a tee. We hope it helps you get through long sessions of tattooing or anything active you do.
