Silicone Swim Caps
Silicone swim caps are, by far, the most popular choice for modern day swimmers. These swim caps are easy to put on, provide a great, streamline fit, and can last for seasons when cared for properly.
Silicone vs. Latex
Before silicone was used in swim cap manufacturing, latex was the most popular material used by swimmers. Silicone caps were originally manufactured for people who suffered latex allergies, but other swimmers quickly got a hold of the great material. Latex and silicone are quite similar in the way they perform in the water. Silicone is slightly thicker than latex and is a bit more durable in the long run. Unlike latex swim caps, silicone caps apply more streamlining pressure to the head and won't wrinkle or bunch when fitted properly. Because of these advantages, silicone caps tend to be more expensive than latex caps, but swimmers who know their stuff gladly pay the extra dollar or two for the highly trusted material.
Silicone is able to stretch and fit over a wide variety of head sizes. They might look small when not on in use, but rest assured that the material is quite stretchy. Because of its excellent shape memory, it holds tight to the head while swimming. This creates an unbeatable streamline effect. Silicone caps are great for competitive swimmers because they help reduce the amount of drag the head produces.
Many swimmers enjoy wearing silicone swim caps simply because of their high level of comfort. Unlike rubber or even latex, silicone won't snag or pull at hair. This is especially beneficial to children, or any other swimmer, with a sensitive scalp. These caps are able to stretch and fit over most any hair thicknesses and length. But, because the material does provide such a sleek fit, long-haired users might have a problem with the caps slipping off of their bulky locks. Although they are highly recommended for swimmers of all ages and sizes, silicone swim caps work especially great for users with small to medium sized heads and those with short or normal length hair. If you do have long, curly, or thick hair, try a long-hair swim cap instead - they're designed with a larger pocket in the back to house a bun or ponytail.
