A general sizing guideline based on board length:
- 8” for 6’7” & under
- 8.5” for 6’8” to 7’5”
- 9” for 7’6 & over
The CI Single-Fin is also an ideal pairing for those looking to ride their CI Mid as a single-fin. This fin can also be used with the CI Mid sidebites for longer boards in the 9-foot-plus range.
