The Best Swim Cap Reviewed

A swim cap is an essential part of your swimming gear. It not only keeps your hair out of your face while you are swimming, but it can also protect your hair from the damaging effects of chlorine, sun, and salt. A swim cap can also reduce resistance from water flow around your hair and create a streamlined effect around your head to help you swim faster and perform better in the water.  

Now you might think, well, a swim cap is a swim cap, but there are some brands and designs that are better for leisure swimming and others that are designed specifically for competitive swimming.

Buying Guide for Swim Caps

There are a few important factors you need to take into consideration when shopping for the best swim cap. You will want a swim cap that efficiently protects your hair from chlorine, sun, or salt, depending on what type of environment you are swimming in; a swim cap that fits well and doesn’t slip off while you are swimming; and one that is designed to create a streamlined effect in the water.


A swim cap should keep your hair out of your face while swimming.

Type of Material

There are four types of swim caps on the market: silicone, latex, nylon, and thermal caps. Each swim cap material has its character and uniqueness and is ideal for a specific type of swimming environment.

Latex Swim Caps

Latex swim caps are comfortable and cheap and perfect for casual swimmers where the primary concern is comfort. Latex swim caps do not have a long lifespan, so they aren’t a good bet for people doing a lot of swimming or training on a competitive level.

Nylon Swim Caps

Nylon swim caps are also comfortable and inexpensive but are quite thin, so don’t protect your hair very well. They are the best swim caps for casual swimming in the open water as they offer better protection from the sun and salt than from chlorine.

Silicone Swim Caps

Silicone swim caps are the preferred choice for most swimmers, although some people might find them quite a tight fit. Silicone is thicker than nylon and latex and therefore lasts much longer. It also offers better protection against chlorine, salt, and the sun, and its thickness creates good streamlining in the water.

Thermal Swim Caps

Thermal swim caps are designed from silicone materials but have their thickest consistency of all the swim caps to keep swimmers warm in cold water temperatures. Thermal caps are also great for protecting your hair against any damage from the sun, salt, or chlorine.


There are different types of swim caps on the market.

Size

The size of a swim cap is a crucial factor when buying a swim cap to ensure you are comfortable in the water. There are three sizes for swim caps:

Ø  Small (20 ½ to 21 5/8 inches)

Ø  Medium (20 ½ to 21 5/8 inches)

Ø  Large (22 ¾ to 23 1/8 inches)

Silicone and thermal swim caps tend to be slightly tighter than nylon or latex caps as they are thicker, so it may be best to buy a size larger than normal if you are a casual or leisure swimmer.

Design

Swim caps come in a wide array of funky colors and designs so if you want to stand out in the pool then you’ll have a wealth of options to choose from.

Weather

Oddly enough, another thing to keep in mind when buying a swim cap is the weather. If you are an outdoor swimmer, silicone swim caps tend to warm up quite quickly and get very hot, so the latex swim cap is a better option for open water swimming.


Latex swim caps are better for open water swimming.

Taking Care of Your Swim Cap

It is important to take care of your swim cap, no matter what material they are made from to ensure they last as long as possible. The best way to look after your swim cap is to rinse it off with fresh water and let it air dry after your swim. Once dry, rub some baby powder into the cap – this maintains the elasticity of the cap and makes it easier to put on.
