Hello all. I have a fullsleeve Orca Pflex size 9. I used it in about 5 olympics over the last 4 seasons. I've gone to a sleeveless so I don't need this anymore. It's in great shape(no nicks or tears). I've washed it immediately after use and stored it in a closet inside out when not in use. You can take a look at the Orca website for sizing. These do fit very snug. I am technically a size 8, but this fits much better.
