The Plain Moulded Silicone Cap from Speedo is a performance swim cap in an ergonomic 3D design to give an excellent fit. The moulded design ensures a smooth, sleek fit with no wrinkles to give you a more hydrodynamic shape in the water, improving your speed and performance. This silicone cap is very durable, ideal for frequent swimmers.
I have a small head but found this cap tighter than my previous silicon cap but that is not such a bad thing as I was forever having to rearrange my last cap as it would slip upwards. Don't particularly like wearing a cap but swimming every day leaves my hair dry and dull otherwise. This was does the job of protecting my hair. I have short hair - not sure how easy it would be to fit a lot of hair into due to the tightness.
