Sporty and Seductive It's the '80s all over again, and we're totally here for it. Modus Vivendi's Blue Otter Collection goes heavy on the vintage vibes with styles that are seriously sporty and seductive. To drive 'em wild on date night, choose from tanga briefs, trunks, boxers, jock-briefs, and much more… and when it's time to burn a few calories, reach for the sleeveless hoodie and snug sweat shorts. There's no going wrong here, unless you hesitate… none of these styles are gonna stick around for long!
