great value - two thicknesses
These caps are an extraordinary value, and they have no words or logos on them, an important consideration for some swimmers.
These come in two thicknesses. The thicker silicone (such as black, orange, turquoise, forest green, red) is too snug a fit for some swimmers. The thinner silicone (silver/gray, blue, yellow) is preferred by most of "my" swimmers. One cap ripped in half after about ten uses, but eleven others have been in use for a year or two without problems.
The caps run smaller than average so these would be great for young swimmers, not so great for bigger kids.
