What is the recommended care for Crossfly underwear?

Our comfortable men's underwear is designed to withstand standard washing conditions. You can wash them at temperatures up to 40 degrees Celsius and dry them naturally or on low heat. We advise you to wash Crossfly products with similar fabrics and avoid abrasive materials, like towels.

The same goes for socks, please wash them in low to mid temperatures and dry them naturally.

Does Crossfly underwear cater to all body types and sizes?

Yes, we offer sizes ranging from 29 inches to 45 inches (XS-XXL). We aim to make everyone feel confident in Crossfly.

Please refer to the size guide for more information. In short, the IKON / IKON X Style fits slightly larger due to the stretchiness of the Modal fabric so if you are in-between sizes, we recommend you opt for a size down. By contrast, the Pro 7" Boxers in our performance series fit true to size.

Should you require additional sizes or have any feedback, feel free to contact us at hello@crossfly.com.

Is there a size chart available?

Absolutely! You can
find our size chart here.

Please be aware that the IKON and IKON X styles fit slightly larger due to the stretchiness of the modal fabric, so we advise you to go one size down. (Eg: if you’re an M/L or 35” waist, please opt for a Medium) By contrast, the Pro 7” Boxers in our Performance Series fit true to size.
