Speedo PowerFLEX Eco Must Be It Youth Jammer Swimsuit

The suit is true to size, but a little looser or less elastic (I'm not sure which) in the legs compared to his other Speedo and Nike suits of the same size. Also, the legs seem a hair longer than his other Speedo jammers. I bought the size 24 for my son, who is average build (not skinny, not chubby, but muscular). Other Speedo and Nike jammers fit him well. This Speedo PowerFLEX Eco seems looser around the legs compared to the others. On him, it is tight enough--the fabric is taught against his skin, not loose-fitting--but is definitely looser or less elastic (not sure which one) than his other suits. Also, the legs seem a bit longer. Most of my son's suits sit above or at the knee. These come below his knee. If your swimmer is skinny, I suggest ordering a size smaller than his normal size.
