Details The all-new UnderFlex Boxer Briefs combine flexibility with compression, so you're supported whether at work, sport, or play. Polyester/spandex construction is comfortable and "made to move" as you move, while being highly breathable with excellent wicking properties, so you keep cool and dry. You can wear your UnderFlex Boxer Briefs on land or in the water, as they're built to work in dry or wet environments. Wear them at the gym, the yoga studio, or for a night on the town. UPF 50+ sun protection is built into the fabric, so they're a great choice for under your trunks at the beach, or under your wetsuit. And once the top layers fly away, your significant other will love the way UnderFlex looks on you as much as you do. Likewise, UnderFlex doesn't believe its customers need to be walking advertisements after the clothes come off, so UnderFlex Boxer Briefs sport no external logos, on the waistband or elsewhere. UnderFlex's UnderFlex Boxer Briefs offer the perfect balance of support and comfort, at a great price. For those who want a looser fit, UnderFlex recommends ordering a size up.
