They keep loose hair from coming loose inside the pool, as well as keeping your hair out of your face. Few things will throw you off more than finding yourself blinded mid lap by a head full of hair.

But perhaps most importantly, the best-domed swim caps will also make you more hydrodynamic while swimming, especially if you have long hair. Why? Well, the longer your hair, the more drag it creates while swimming. When even a fraction of a second matter, you’ll want a wrinkle-free cap that cuts through the water like a hot knife through butter.

What is a Swimming Cap?

A swimming cap is a closely fitting cap that competitive and casual swimmers can wear in the pool. They are mostly made of rubber, latex or Lycra, and are referred to as caps for bathing or swimming.

Why Wear a Swim Cap?

There are many reasons that individuals want to wear caps for swimming. Some swimmer would prefer to keep their hair and shield it from chlorine or sunshine. This helps maintain healthy hair, particularly for those who regularly swim.

On longer swim hours, wearing a swim cap will help keep the head of a swimmer warm, ensuring the wearer can tirelessly save more energy while their body keeps an ideal temperature during training.

To avoid the drag that long hair can cause, competitive swimmers wear their hair in a cap. This drag will slow them down, so it can minimize those extra critical seconds by getting the hair out of the way.

The ears’ security is one of the most common explanations for caps to be worn by children. This can help avoid ear infection, mainly when worn with earplugs, and prevent water from going into the ears.

Materials Swim Caps are made from

Swim caps are swimming gear that is crafted from several diverse materials. Silicone, latex, rubber, and lycra/spandex are the most common, but you may have come across plastic, neoprene, and polyurethane caps.

Silicone Caps

One of the most common fabrics used for swimming caps is silicone. It is, in fact, highly robust. Silicone caps, when appropriately cared for, will last for years. Silicone is undoubtedly my preferred material for caps as a professional swimmer. Not only is it long-lasting, but it also lends itself well without dragging hair to slide on and off.

Latex Caps

Latex is a plastic much more refined than silicone. Often, it is less durable. Especially if you do not put them on correctly or forget to take good care of them, Latex swim caps rip more quickly. Since they are lighter than silicone, latex caps provide for “breath-ability.”

These caps could be the best fit for colder temperatures in which heat loss is not a concern if less heat is stored. Generally, latex cap is often much cheaper than most kinds of caps. So if you’re looking for a cap that won’t crack the bank and it’s not a question of durability, then the way to go is latex.

Lycra and Spandex Caps

Lycra is a brand name for a fiber composite usually referred to as spandex or elastane. Swimming caps made of spandex are very durable and can generally last for a long time after each use, even if rinsed with chlorine. They are considered to be lightweight and will never snag or tug your hair. However, because Lycra is a fabric, these caps would allow water to flow when swimming through the material.

A material with a porous cap is not as useful as silicone or rubber but can also minimize drag to a greater degree than wearing no cap at all. Lycra swim caps are not suitable for use in sport because of this. For practice or sun defense, they can mainly be used. When wearing your silicone race-day hat, wearing a higher resistance cap during practice will also make you perform better. When it comes to competition, making the body used to a higher degree of resistance will improve results.

Neoprene Caps

Neoprene is a synthetic rubber that is widely used in wet suit fabrics. The aim of a neopren cap, just like wet suits, is to hold a thin layer of watertight to your body to serve as insulation. For individuals who swim in freezing pools, streams, rivers, or the ocean, this makes neoprene caps an outstanding alternative.

However, you would also need to wear a wet suit: contrary to the common misconception that 45% of the heat loss is from your head, the head generally accounts for just 10% of the surface area of your body. So, a thermal swim cap can only support you if it also protects the rest of your body. Neoprene swim caps are more appropriate for open-water swims since they do not effectively minimize drag. Neoprene caps do not, however, pull hair.

Sizes and Shapes

Usually, swim caps come in the following sizes and shapes:

  • For kids, swim caps are bigger than normal ones. For your kids, choose these kinds of caps.
  • For adults with short hair, choose caps of average size. As the swim caps can comfortably extend to conform to the actual head shape and height, they match most head styles.
  • Adult swim cap for long-haired. Typically, a long hair swim cap is an inch or two longer to help trap long hair or keeping your hair within the swim cap.
  • The so-called bubble swim caps. These have a more helmet-like form, and tiny bubbles cover their surface.

Most on this list are made up of silicone. Thanks to their wrinkle-free fit, while silicone caps are more durable and much more hydrodynamic, they are often more costly than the standard rubber swim cap.

What is the purpose of a swim cap?
The primary purpose of a swim cap is to protect the hair. If you're swimming someplace with chemicals in the water, your hair can take on an unwanted greenish hue and emit a fishy smell. Swim caps aid in blocking these smells from developing and help to keep chlorine from damaging your hair by keeping it out of the way.

Do swim caps really work?
Swim caps work by eliminating drag; this helps you swim noticeably faster because your not having to pull your hair behind you. They also keep the majority of chlorine out of your hair, which protects it from damage.

Do swim caps go over ears?
Swim caps can go over your ears, but they don’t have too. Keep in mind; they will not prevent water from entering your ears.

Is there a waterproof swim cap?
No, there is no fully waterproof swim cap. Your head will be traveling underwater, often making tilting motions. It’s inevitable that some water will get in.

Should you wet your hair before putting on a swim cap?
If you seal a dry wet suit to your body, it will take a long time for all the air pockets to get squeezed out. Same thing happens with hair trapped under a swimming cap. So definitely, it's best if your hair is wet before putting on the swim cap so that everything stays put until you're done swimming and ready to rinse off.

How tight should a swim cap be?
It largely depends on the individual head size - so go with what fits you best. Tight enough to keep your hair from escaping but not so tight it pushes in all of the water away from your ears and scalp, which will make it difficult for you to hear

Can swim caps cause hair loss?
If a swimmer is wearing their swim cap for long stints of time, or if they are "hot" swimmers this could put too much pressure on their scalp and cause follicle damage, which might lead to temporary hair loss. It's important to take a break every once in a while so that you can let your scalp's elasticity and hydration come back into balance.

Is silicone or latex better for swim caps?
Latex is good for people who don't have latex allergies, but it can feel heavy and tight on your head. Silicone can feel a little softer and wouldn't irritate your scalp or make your hair difficult to comb out after wearing one all day, so it might be more comfortable in that respect. But if you do pick silicone because you want to avoid any type of latex, I've had some swimmers complain about how stiff they were before they got wet.

How do you loosen a swim cap?
If your cap is too tight or has never been worn, try stretching it out. Place one hand on top of the other and twist them towards each other at the base of your head. Use that force to pull back and move to front over your hair.

What size swim cap do I need?
Swim caps come in different sizes. Some are one size fits all, some come in small, medium, and large. These are usually racing or open water neoprene caps.
