Swimming 101 – Swim Cap Basics
The sun is high and the swimsuits are ready. Yes, the best time of year has arrived for lovers of the pool and beach everywhere. It’s swimming season.
Okay, so technically, swimming season is all year when you have access to indoor pools, but there’s something about the warm sunshine that encourages water activities. Either way, if you’re swimming in the dead of winter or the middle of summer, a swim cap is often the must-have accessory people with hair like to have on them.
Before we take a deep dive into what the best swim cap options are, let’s first discuss the reasons for wearing one.
- A cap makes you swim faster.
- It keeps the chemicals in a pool from damaging your hair.
- They make you more visible, which is good for safety.
Now we can get into the types and what works best for different hair, accessories, and activities.
Swim Cap Basics
There are various types of materials that go into swim caps. Here, we’ll discuss the differences between the materials and what they are best suited for.
Swim Cap Latex
For a century, latex has been used to flatten hair on the head when getting in the water. It gives the tightest fit, which makes the cap quite a squeeze to get on. However, you feel confident knowing it’s not going anywhere. They’ve been proven to be the best at reducing drag in a competitive environment.
The major thing to watch out for with latex is allergies. Before committing to a latex cap, do some mild exposure to one spot on the body. The last thing you want is to have a head wrapped up in latex for several hours and be allergic to it.

Swim Cap Silicone
A silicone cap is more popular today due to its flexible fit. They definitely have more of a squish factor, which makes them more comfortable to wear. Long-time wearability bumps up the interest of swimmers expecting to be in the pool for long periods of time, as well as those who have issues with latex.

Lycra Swim Cap
Coming up next are two materials that are growing in popularity. Both Lycra and polyester are probably best suited for ocean and lake swimming. The reason is they are not airtight, meaning chlorine from a pool can still cause damage to your hair. They are the most flashy of swim cap materials, though.
Because they are made more to show off than function, Lycra and polyester caps are more durable. The materials don’t have to work as hard because they aren’t using their energies toward keeping a grip on your head.
Something that might annoy a wearer is that they are more prone to sliding down or off entirely. So, they are probably best saved for the casual swimmer, a swimmer with short hair, or someone who swims only in short bouts.

Best Swim Cap To Wear With Goggles
Silicone swim caps are the best to wear with goggles because they are wear-resistant. The flexibility of the silicone caps makes them more open to things like goggles, making an impression on them.

Here are a few of our favorite silicone caps.

Best Swim Cap for Long Hair
One of the most annoying things about having long hair is trying to figure out what to do with it in the water. When your hair isn’t too long, getting your hair wet can be a quick towel dry before you’re onto other things. Long hair is a whole other story. The amount of dripping and loose hair is unreal.
Deciding to keep it locked up isn’t as fun as it sounds, either. The longer the hair, the more the effort to get each strand tucked into a cap. It can be tough, especially when they are formulated to stick to the skin. Stuffing a cap full of hair on top of it can feel like an unwinnable battle.
What you need is a silicone cap that stretches enough to make enclosing your long hair attainable.

FAQs
Should I wear goggles underneath my swim cap?
Yes and no. It depends on what you’re doing out in the water. Probably the best answer for anyone is yes because you know that they aren’t going anywhere. However, if you’re having a fun day at the beach, you may want to take the goggles off and on without any disruption to the hair under the cap. No one wants to have to recap multiple times throughout the day. Also, children might appreciate the ability to take the goggles off and on, which would be another reason to keep them on the cap.
Are swim caps supposed to keep hair dry?
Swim caps aren’t technically designed to keep hair dry. However, depending on the material you choose, it may more or less do so. Remember, latex and silicone have the tightest fit, so they are the ones most likely to keep hair dry. Definitely avoid Lycra or polyester if you’ve got an event after your swim.
Can I double up on swim caps?
Sure! Actually, people who like the look of a Lycra or polyester cap but need more coverage opt for putting a latex or silicone swim cap underneath. It’s sort of like having the best of both worlds. It’s also handy for someone who is nervous about having goggles tug at their hair under the cap. They will put on one cap to cover the hair, put on the goggles, then place another cap over that.
How to put on a swim cap with long hair?
Pull the hair back to the crown of the head and gather it into a ponytail. Wrap the hanging hair into a loose bun and then, use a thin elastic band to hold it in place. The idea here is that when you pull the cap down, the bun squishes against the head and will lay flat. You may want to lightly mist your hair before pulling on a swim cap, which sometimes helps. It depends on the newness of the swim cap. Stretch it out a tad and match up the seam to the middle of the forehead. Remember, pull it down from the crown. Tuck in any loose hair.
