I like the product and my experience of customer service has always been good. The “uplift” that these pants provide is great and better than others I have tried. My only criticism is that the produ... See more

At 78 and having always worn briefs type underpants I decided that perhaps I would try boxers. I tried pairs from a well know High St store and also from a well know brand of boxers. Neither provided... See more

About Crossfly
Written by the company
Crossfly was created to redefine everyday comfort for men. For too long, men have settled for outdated designs and average-quality underwear, while women’s underwear has evolved with innovation, support, and premium fabrics. We’re here to level the playing field — with performance-driven, intelligently designed products that put comfort first.
Born from a small team of UK and US sportswear professionals with decades of experience in product innovation and marketing, Crossfly was created with a simple mission: to elevate men’s everyday comfort through intelligent design, premium quality, and sustainable thinking.
We’ve poured our expertise into creating a lifestyle brand that puts performance, durability, and comfort first. Our underwear and socks aren’t just everyday essentials — they’re your go-to, must-have gear that supports you through work, sport, travel, and everything in between. With every Crossfly product, you’ll feel the difference from the moment you put it on.
What Sets Crossfly Apart?
Unmatched Comfort: Our Cocoon internal pocket system offers all-day support, eliminates friction, and keeps you cool — so you can focus on life, not discomfort.
Innovative Design: The X-Fly reimagines the traditional Y-front with a faster, smarter, one-handed access system that just makes sense.
Premium Fit: Our ZeroFold360™ Waistband moves with your body and stays smooth — no rolling, no digging, just pure comfort.
Feel-Good Products in Every Way We don’t launch anything unless it improves on what came before. That means using superior materials that feel better and last longer than the competition. And where possible, we choose sustainable options, from responsibly sourced fabrics to 100% recyclable packaging. Because looking after the planet is part of feeling good, too.
Our Vision: Take Comfort to the Extreme Whether you're pushing limits or just getting through a long day, Crossfly is designed to move with you, support you, and make you feel great doing it. Once you’ve worn Crossfly, you won’t want to go back.

Thank you for the review. We appreciate it. 🙏
Very comfortable control.
I was really pleased with the feeling and fit of the six inch boxers, everything is kept nicely in place without any chaffing. True to size and very comfortable to wear.

Hi there, thanks for taking the time to write a review. We're sorry to hear you found the pouch too small for you. We'd love to help you find a better fit; please get in touch with our team.
Center of pouch too loose and baggy, no support
While the sides of the pouch felt more supportive the center of the pouch is too loose and baggy giving no support at all.

Thanks for taking the time to write a review. We're sorry to hear that you did not feel the pouch gave you ample support. If there's anything we can do to help you find a better fit with another style or size, please don't hesitate to get in touch with the team.

Easy ordering and prompt delivery
Easy ordering and prompt delivery. Was rather surprised at the size of box for a single pair of pants. Was expecting a small package that would fit through the letterbox, otherwise I would have left the porch open for him to deliver into. By chance I happened to be at home when he called, so no problem.
