Introducing Neon Strikes - Where Bold Meets Comfort
Make a statement with our limited-edition Neon Strikes colorway, featuring an electrifying combination of deep purple and vibrant hot pink accents that bring serious energy to your everyday essentials. This eye-catching design isn't just about looking good—it's engineered for all-day comfort and performance.
Why You'll Love Them:
Our trunk is specifically designed for shorter guys or those with slimmer legs, featuring a 4-inch inseam that provides the perfect proportions for your build. With a streamlined design, you get a smooth, minimalist fit that eliminates bulk and provides unrestricted comfort from morning to night.
Our innovative 3D Comfort Pouch features hidden elastic architecture that contours naturally to your body, keeping everything perfectly supported without compression or adjustment throughout the day.
Say goodbye to the dreaded ride-up and chafing. Our UltraGlyde™ panels are strategically placed along the inner thighs to ensure your trunks stay exactly where they should, whether you're at your desk, at the gym, or on the move.
Sustainable Luxury:
Crafted from super soft bamboo viscose (95% bamboo viscose, 5% spandex), these trunks feel incredible against your skin while actively wicking away moisture to keep you cool and dry. Plus, they're produced using an eco-friendly closed-loop system, so you can feel good about your choice.
Risk-Free Confidence:
Try them with our First Pair Guarantee—if you don't absolutely love them, they're FREE. Mix and match sizes, colors, or styles to create your perfect multi-pack.
Limited edition Neon Strikes colorway—grab yours before they're gone.
