Jaked swimsuit, blue, green, and black color scheme. The back side is made of a wetsuit-like material to provide buoyancy. The buoyancy of the swimsuit can compensate for the sinking of the lower body. I bought a size LL, which was too big, so I used it once in the pool, but I'm selling it. (The back floats, so the fit should be snug. My waist is 79cm) No stains, tears, or odors. Color: Green系 #Swim #Swimming #Triathlon #Pool #OWS #Openwater
