Apex Endure Briefs
A high-rise waistband with no-slip design provides maximum security and coverage through the most dynamic water activities — paddleboarding, surfing, triathlons, and lap swimming.
Custom trimmed netting at the front is the London Bridge Collection's signature design detail. LYCRA® SPORT construction is both chlorine-proof and fade-proof, so the artisan print stays vivid session after session.
Flat-lock stitching, moisture-wicking fabric, and UPF 50+ complete a brief designed for athletes who want performance and wearable art in a single piece.
