Choosing a Swim Cap


When it comes to swimming caps, there are almost too many choices. You might be wondering if the extra cost of the silicone caps are worth the expense, which cap is most likely to keep your hair dry, and, which swim cap you should buy.

Here is a brief run-down of swimming cap facts, followed by some considerations to weigh when deciding which swim cap is right for you.

A Quick Primer on Swim Caps

Swim caps come in several materials, but the vast majority (and most popular) are made of latex or silicone. Latex caps are inexpensive and relatively thin. Silicone caps are thicker, longer-lasting, and more expensive. A few swimmers prefer the old-school spandex caps, while Olympians these days wear molded silicone caps, which are designed to be wrinkle-free (and thus, hydrodynamic)! But before we go any further, let’s get one thing straight: regardless of the material, no swim cap will keep your hair completely dry.

Choosing a Swim Cap Material

Consider these four factors to decide which kind of swim cap might best suit your needs.

Swimming Frequency

If you swim every day, you’ll want a cap that is durable. And if you swim infrequently, you’ll want a cap that can survive a long, lonely, possibly damp week (or four) in the bottom of your swim bag. In either case, silicone may be your best bet. It’s stretch-resistant, and thus more durable for daily use. And it’s more forgiving when it gets forgotten in the bottom of your bag for weeks at a time. Latex caps, on the other hand, when left for long periods of time (even when completely dry), eventually turn into a sticky, plastic-ey goo that bonds permanently to goggle lenses and bathing suits.

Thus, if durability is your main concern, then silicone is the way to go. Of course, this begs the question: why would anyone buy a latex cap anymore? Well, the short answer is: because durability isn’t the only thing to consider…

Water Temperature

Do you swim in a pool that is used for swimming lessons or water aerobics? Is your pool temperature more than 81 degrees? If you answered yes, you might want to think twice before purchasing a silicone cap. The extra thickness of silicone is durable…but also nice and warm. Latex caps, thanks to the fact that they are relatively thin, will keep you from over-heating as quickly as you would in a silicone cap.

On the other hand, if your pool is on the cool side (80 degrees F or less) you may need a warmer cap. And in that case, go for silicone.

Workout Intensity

Pool temperature is not the only thing that determines how comfortable you are in the water, however. If you are swimming hard in a pool that is 80 degrees F, pretty much any cap (latex included) may have you feeling a bit toasty. So, it’s a good bet that if you are working out with a Master’s team and spending an hour or more swimming with your heart rate in the upper end of your aerobic zone, you’ll want to use a latex cap. (And then see below for how to prevent goo-formation!) On the other hand, if you are swimming nonchalantly or doing water aerobics or just learning how to swim, the added warmth provided by a silicone cap may be welcome and/or necessary.

Hot Tip: Caring for Your Swim Caps

Latex swim caps (especially the super-cheap ones) have a tendency to degrade when left to their own devices in your swim bag. You’ll prolong the life of your caps if you pat them dry – inside and out – after every workout, and hang them somewhere so that they can completely dry out between uses.

Team Membership

If you belong to a team, you should definitely sport your team logo on your head! It’s more fun when everyone at practice is wearing team colors. And at a meet, it makes it easier to pick out your teammates, whether they are in the warm-up pool or on the blocks in the next lane over! And if you go with the team cap, the only thing you’ll have to decide is whether you want to cover your head with silicone or latex.

Special Occasion Swim Caps

Finally, there are some “special occasion” swim caps, which you may find useful at some point in your swimming career.

If you are doing any open water swimming in cold water, don’t leave home without a neoprene cap. (Neoprene is the material used to make wetsuits.) Try it once, and you will probably find that cap to be an essential piece of equipment, especially if you are swimming sans wetsuit. If the water is really cold, you may want to sport a silicone or latex cap under the neoprene one.

[Img_Popup_13561106082010101251.jpg]If you are participating in a “Turn Back the Clock” event, you’ll need a rubber-looking "bubble" cap! You can get them with or without a chin strap, and they come in classic white or hot pink (see left). Celebrating Earth Day with an open water swim? You can sport one of these retro caps covered in flowers. Although, fair warning: the flowers are not in earth tones.

Will a silicon cap protect your ears from water

Hi Lynn!
You would need a pair of ear plugs to protect your ears from water, a swim cap will not do so.

my seven year old is on a rec swim team and her wearing a swim cap is an issue. she is complaining that her swim cap is too tight.

I'm looking at adult swim caps but what material is most comfortable, latex, silicone, or lycra?

any advice is greatly appreciated.

Hi Michael!
The most comfortable material is definitely the lycra but this will not keep her hair dry at all. The next comfortable material is latex, and lastly silicone. We hope this was helpful!

Are there any swim caps that will keep my hair dry? Or at least, staying just a bit damp? I do a lot of floating and color my hair so I really want to keep it as dry as possible.

Hi Laura,
There are no swim caps that will keep your hair dry/damp. I would suggest using a shampoo to wash your hair after your swims, for example the TRISWIM Shampoo 8.5oz (https://www.swimoutlet.com/p/triswim-shampoo-85oz-3783/) It's safe to use every day and on chemically treated hair. I hope this helps!

Do either Latex or Silicon block the signal from your garmin if you put the device under your cap? (haven't been able to get any data except from before when I actually put it under my cap & I don't know whether my cap is latex or silicon: I suspect silicon as it is quite thick and several years old and still in good condition)

Hi Meg,
That I'm aware of it wouldn't block the signal when wearing a latex or silicone swim cap. You might have a silicone cap since they tend to be thicker and last longer than latex. I would suggest you contact Garmin directly 1 (800) 800-1020 so they can assist with troubleshooting.

I am doing an open water race in the Middle East. Its very warm water and very high air temp. What swim cap materiel is best, so I can be seen but do not over heat?

Hi Chris,
Latex caps are better for warm temperature because they have thinner material compared to silicone.
