What Makes Flex® so...Flexible?

Flex® is the first graphene condoms in existence and our most adaptable condom yet - literally.

Made with Sensatex™, our softer, stretchier latex, Flex® moves with you for a barely-there feel and a whole lot of comfort.

What’s the Flex® Appeal?

Flex® is what happens when thoughtful design meets next-level intimacy. Crafted with space-grade graphene - one of the strongest, thinnest materials known to science - and ultra-soft latex that adapts to your body, it’s engineered for connection that feels...easy.

Powerful, subtly high-tech, and made for people who care about how things feel, not just how they work.

Bedroom Approved

Bedroom ApprovedIn a clinical trial, users preferred ONE® Flex® 2 to 1 over standard latex condoms. 



Why? The difference is in the feel. With its soft, stretchy design and cutting-edge materials, Flex delivers a more natural, comfortable experience — and once people tried it, they didn’t want to go back.

What is the ONE® Flex® graphene condom?

ONE® Flex® is the first condom in the world enhanced with the wonder material graphene. Graphene is the thinnest, strongest, and most conductive material on the planet. When bonded together with latex, it creates a new condom material that is super thin and flexible – and features 85% better heat transfer than standard latex condoms. 

What is graphene?

Graphene is a nano material that is 200 times stronger than steel and 1 million times thinner than human hair. It is also the most conductive solid ever discovered.

Our scientists spent nearly ten years developing a hybrid condom by molecularly bonding graphene with natural rubber latex, resulting in one of the world's thinnest condoms. When bonded together, graphene molecules fill the space between latex molecules, creating a new material that advances thinness, flexibility, and thermal conductivity. The result is a comfortable condom fit that enhances pleasure, connection, and sensation.

Graphene was discovered in 2004, quickly capturing international attention as the thinnest, strongest, and most conductive material on the planet. NASA calls graphene a "wonder material," in reference to its unmatched capabilities. The discovery of graphene has been a catalyst for innovation across industries, including space travel and renewable energy. And now, condoms!

How does graphene help with heat transfer?

On its own, latex is an insulator, which keeps you from feeling your partner's natural body heat. Graphene, on the other hand, is the most conductive material on the planet. Because ONE® Flex® molecularly combines latex with graphene, the condom increases body heat transfer by 85% compared to standard latex condoms. This results in more sensation and a natural, skin-on-skin feeling.

How does graphene help make condoms thinner and comfortable?

One of the top complaints about ultra-thin latex condoms is a tight and restrictive feeling. The reason is as latex gets thinner, there is less material to stretch. When combined with graphene, latex can stretch farther without feeling tighter. Due to the capabilities of graphene, ONE® Flex® condoms are ultra-thin without losing flexibility, sensation, or comfort.

Are ONE® Flex® condoms cleared by the FDA?

Yes. ONE® Flex® condoms are cleared for sale by FDA and Health Canada for the purpose of preventing STIs and unintended pregnancies, and the technological advancement is safeguarded by a patent.

What color are ONE® Flex® condoms?

Thanks to carbon-based graphene, the ONE® Flex® condom has a natural charcoal hue.

What are the ingredients of ONE® Flex® condoms?

All ONE® Condoms are made with natural rubber latex, dusted with cornstarch, and lubricated with premium, medical-grade silicone lubricant. ONE® Condoms are also vegan-friendly, non-GMO, nontoxic, and free from any harmful chemicals. All ONE® Condoms are packaged in tubes made from 100% recycled paper.
