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 For too long, men have settled for outdated designs and average-quality underwear, while women’s underwear has evolved with innovation, support, and premium fabrics.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.

The separation pouch is joke!
The separation pouch is joke. Too wide and definitely doesn't cradle my balls. Too expensive to buy again since they don't hold up to my expectations.

X opening
The X opening should be lower, after being used found out the waistband reposition lower so it curls over, making discomfort, had to disposition by loosing trousers belt.

Very nice but not for me.
The service from CF was very good and quick. I liked the fabric and general fit but they just weren't for me, unfortunately. Sent first pair back for refund and was treated very well.

Thanks for the excellent review and recommendation to others!
A great product with a great fit.
It was the E-mail informing me of a great sale on selected products that caught my attention. I had a second chance to buy the product in a smaller size and see if it would make a difference. It did, and now I see how well the cocoon pouch works.

We were so close! 4 out of 5, we'll take that! Thank you for the great review, we hope to see you back in store soon and maybe we'll get that 5 star 🙏
Very Comfortable and True to Size
Very comfortable and well constructed. Usually very pricey but got them on a Black Friday special at a great price.

Poor Customer Service
I was at the end of the purchase procedure and then noticed that I was 1p short of the free delivery label.
I immediately emailed Crossfly asking if there was any way they could process the order without a delivery charge, I received the standard reply saying they would get back to me within a few days. Well, more than a few days passed so I sent them a gentle reminder requesting a response, no response, apart from more special offers as I am a subscriber [this will read was a subscriber shortly].
If I had received some sort of response I would have considered paying the delivery charge, but for me this was really poor customer service from this company. I did not place the order so they lost the sale for the sake of 1p and a lack of customer service.

Thank you for taking the time to share your experience, and I’m really sorry for the frustration this caused. I completely understand how disappointing it must have been to be just 1p away from free delivery, reach out straight away, and then not receive a timely response from us. That’s not the level of service we aim to provide. During this busy weekend over Black Friday, our team had been working as fast as they could. But, I apologise that we let you down here.
As such, please check your email, and you’ll see we’ve sent you something to help make this right.
Thank you again for the feedback. All the best, Crossfly

Crossfly make the best
Crossfly make the best (imo) men's underwear available, comfy, well made, supportive, wears and washes brilliantly and fits like the proverbial.
The only issue is the upfront price but excellence was never cheap
