Next-level Gym Gear The cutting edge should always be comfortable. Designed by Modus Vivendi, the Slub Line was created to elevate your downtime — whether you're working up a sweat at the gym or relaxing at home. (That’s our euphemism for sex, and frankly, it needs work.) Choose from short-sleeved tees, casual pants, sleeveless tops, standard briefs, Brazil-cut trunks, and backless briefs. Prepare to push the limits.
