Quick answer

Choose MyONE Size 47C for a snugger fit if you need a narrower girth, or Size 49C for a slightly roomier snug fit. Both share the same short length (4.7 inches).

Why width matters more than length here

Both the MyONE 47C and 49C share the same length (Letter C, 4.7 inches), so the key difference is girth. The 47C has a nominal width of 47mm, while the 49C is 49mm. That 2mm difference can significantly affect comfort and security, especially if you're between standard sizes.

A condom that's too loose may slip; one that's too tight can be uncomfortable or break. MyONE's custom sizing aims to solve that by offering precise width and length combinations.

Both are hyperthin and lubricated

Both sizes are made from soft, vegan latex, hyperthin, and pre-lubricated. The material and lubrication are identical, so your choice comes down entirely to fit. Neither offers extra features like ribbing or spermicide, which may be a limitation if you prefer those.

47C vs 49C: Trade-offs at a glance

  • Choose 47C if: You need the narrowest available snug fit. The 47mm width is designed for those who find standard snug condoms still too loose.
  • Choose 49C if: You want a snug fit but with a bit more room. The 49mm width can be more comfortable for longer wear or if you are between sizes.
  • Both share the same length: Length Letter C (4.7 inches) is the shortest option. If you need more length, consider other FitCodes like 47D or 49D. Measure your length before ordering to confirm that 4.7 inches is sufficient.
