Premium Men’s Underwear That Works As Hard As You
At Crossfly, we believe that men’s underwear should deliver on every level - style, performance, comfort, and innovation. That’s why we design premium men’s underwear with patented technologies, sustainable materials, and the all-day support you didn’t know you needed.
Whether you’re dressing for the day ahead or winding down after one, Crossfly’s premium underwear delivers fit, feel and function that go far beyond the basics.
Innovative Technology
From our signature X-Fly® easy-access feature to our ZeroFold360™ waistband, every detail is made to enhance comfort and usability. Our Coccoon internal support system provides breathable separation and reduces friction - ideal for active days, long hours, or whenever performance matters most.
Looking for more performance-driven styles? Explore our range of men’s sports underwear.
Better for You - Better for the Planet
Our Everyday Series is made with sustainable Modal fabric - soft, breathable, and eco-conscious. It’s a choice that feels good on your skin and does good for the planet.
