Quick answer

Choose the MyONE Size 57F if you need a 57mm width with a 6-inch length, or the Size 57J if you need the same width but a longer 7.5-inch fit.

Why length matters even when width is the same

Both the MyONE Size 57F and Size 57J share a 57mm nominal width, which is wider than standard condoms. That shared width means they fit similarly around the shaft. The real difference is length: the 57F is 6 inches long, while the 57J is 7.5 inches long. Choosing the right length prevents the condom from unrolling too far or not covering enough, both of which can affect comfort and security during use.

Material and feel are identical

Both sizes are made from the same super soft, vegan latex that is hyperthin and extra lubricated. They are also triple tested for safety. That means your decision comes down to fit alone, not material quality or lubrication. If you already know you like MyONE's feel, picking between these two sizes is straightforward.

Trade-offs at a glance

  • MyONE Size 57F (57mm x 6 inches): Best for users who measure a 57mm girth and prefer a standard or slightly shorter length. The shorter profile can reduce excess material at the base. Measure your erect length; if it's around 6 inches or less, 57F is likely your fit.
  • MyONE Size 57J (57mm x 7.5 inches): Best for users who need the same 57mm width but require a longer length for full coverage and comfort. If your erect length exceeds 6 inches, the 57J provides the extra length you need.
  • Choosing between them: Since both share the same width, the decision is purely about length. Order a sample pack or try one of each to confirm which feels more secure.
