Size Charts

This page includes size charts for all fabric tails and apparel on our website. If you can't find sizing for your item, please contact us at info@finfolk.com and let us know.

Fabric Tail (Signature and Discovery)

Choose the size that is closest to your personal measurements. Due to the stretchy nature of scuba knit, all measurements stated have additional stretch beyond what is stated vertically and horizontally so if you're in between sizes, please size down

Sizes 6XL and above can be made upon request to info@finfolk.com and must be made on designated tail collection release date (excluding Tail of the Month tails).
