I would STRONGLY ENCOURAGE to swim in the monofin (hard plastic mermaid fin) wWTIHOUT the fabric First, and get use to the natural wave flow motion. the fabric will add a considerable drag to this montion and swimming. Remmeber, this is virtualy binding your legs together and wiehging you down, please be experienced fbefore flopping into the water! Mono fins are accesable by inzipping on the right side of the fabric near the side of the fin inside. so it can be tken in a and out.
