I've needed some new underwear and purchased a myriad of single pairs from different companies. The crossfly won hands down for support and comfort. Grabbed 1 pair of short running socks to see how... 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 For too long, men have settled for outdated designs and average-quality underwear, while women’s underwear has evolved with innovation, support, and premium fabrics.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.

First dealings with Crossfly
First dealings with Crossfly. I bought 3 pairs of socks. The process was easy and the delivery was quick. The socks are great. I’ll be back for more!

Hi Sean, we're sorry to hear this. Your review has been raised with our customer service team and we'll act on it today. Many thanks for your patience while we deal with your case.
I like the material but...,
I like the material. It is very comfortable. I do not like the waistband. It just rolls. It will not stay flat. And I ordered a smaller size than I would normally order and the waistband is still loose.

Many thanks for your review. We're sorry to hear that you found that the waistband rolls for you. On this product, this should not happen. We'd like to recommend that you try the 3" Trunks, where the waistband sits lower on the waist. Another style could be the Lux 4" Trunks, a new and improved product. Hope this helps, Crossfly.

They are extremely comfortable and very nice to wear, perhaps become a little less supportive as they get older and washed more but I like them

Many thanks for taking the time to write a review. We were so close, 4 out of 5! For longer lasting wear, please wash at lower temperatures; 40C max or 30C to save some energy too. All the best, Crossfly

Liked them so much that I wanted to order 7 more pairs but found it impossible to. Wrote an email to customer services last Thursday and am still waiting a reply that my calculations are correct and what to do next.Great product but lousy after sales service.

Thank you for your feedback and for being such a loyal fan of our products! We’re really sorry for the delay in replying to your email — this is not the experience we want for our customers.
We’ve checked your request, and you’re correct that ordering 7 more pairs at the moment isn’t straightforward due to stock limits. Our team is ready to assist you in placing your order or finding the best alternative.

Absolutely THE best underwear EVER!!!
As a person with sensory needs, it's hard to find underwear that ticks all the boxes ... looks good... feels good... doesn't ride up... great design. .. innovative and intuitive ... and even more but I'll run out of space. These tick all my boxes and are just fabulous. I'll buy more that is for certain!!

I ordered the trunks and the fit is excellent. The material quality is excellent, as well. I also prefer the "quick draw fly" and these are quite comfortable as compared to other brands I've owned.
