How to Choose a Swim Cap


Swim caps make you more hydrodynamic in the water and are a great way to keep long hair out of your face while you swim. Choosing a swim cap is fairly straightforward and usually is influenced by what type of swimming you do, but there are a few considerations you should keep in mind when making a purchase.

Lap Swimming vs. Water Exercise

Lap swimming means head-down, face-in-the-water swimming, while water exercise can be anything from aqua jogging, to water therapy, to aqua aerobics. Water exercisers usually use caps to keep their hair out of their face and dry. Athletes doing water aerobics, aqua jogging, or other forms of gentle water exercise may want to wear a LYCRA™ swim cap. These are soft mesh material and will help keep hair out of their eyes without the tight, heat-retaining fit of traditional swim caps. Lap swimmers more commonly use caps to help them move through the water more efficiently and will prefer the hydrodynamic qualities of latex or silicone swim caps.

Practice vs. Racing vs. Open Water

Swim practice caps are made of latex or silicone. They're simple, inexpensive and quite similar from brand-to-brand, and are also commonly used during meets and competition. Modern racing caps are made of molded silicone, which provides a smoother surface and reduces drag during races. They are a bit more expensive than traditional swim caps.

Open water racers or swimmers may want to opt for a silicone or even a neoprene cap which provide a bit more insulation and floatation than latex caps (although latex caps are equally acceptable and widely used on open water swims). Open water swimmers should also consider buying a cap in a bright color to make it easier for officials and rescuers to spot them in the water.

Lots of Hair vs. No Hair

If you have medium to long hair, then a silicone cap will suit you best. Silicone caps outlast their latex counterpart, are more tear resistant, and don't tug at your hair. Typically softer to the touch, a silicone cap is gentler on the hair and easier to get on and off after a workout. Those with longer hair will need a snug fit to keep their cap from falling off. Silicone caps can provide a contoured fit for your personal head size while keeping everything in place.

If you have little or no hair, a latex cap will provide a better fit. Made of latex rubber, the latex cap tends to stretch more easily so they can be worn by virtually anyone. Regular-sized caps fit most swimmers with average head sizes. If an average-sized swim cap feels loose, try a junior or kids cap for a snugger fit. The cap should be tight enough to remain on your head throughout a race or workout, but not so tight that it leaves a line or begins to hurt your head. If you're worried your cap may not stay on, try a swim cap with a chin strap that comfortably holds your cap into place while you're swimming.

Pick What You Like Best

When it comes down to it, there are no strict rules about swimming headwear. Pick a cap that meets your needs, whether it comes down to comfort, insulation, or just the color. And since swim caps are quite inexpensive, it's a good idea to buy a few. That way you're sure to have one on hand in case one rips.

Also consider buying a fun cap! Many companies manufacture holiday-themed caps, caps with funny sayings, or caps with graphics. You can also purchase customized caps that feature names, nicknames, and logos for yourself or a team. A unique swim cap can make hopping in the water a lot more enjoyable, whether for practice or competition.

Hello Valerie!
Any silicone/latex cap should work just fine for you and help protect your hair as well. You can try the Sporti Silicone Swim Cap as it is one of our best sellers. We would also recommend using a swim shampoo to help remove the chlorine from your hair as that could be the cause as well for your hair changing color. The UltraSwim Chlorine Removal Shampoo 7oz is among the most popular swim shampoos that we carry as well.

I'm a small woman with a big head. 23" across and I wear a 7 3/4 in regular hats. Also I am 68 with long white hair getting thinner every year. I live in a hot climate and get in my pool or hot tub every day. I have not had my head under water in several years, as nothing fits, it just pops right back off. I don't care about speed, racing, etc. I want something to cover all my hair that stays on and doesn't cut off the circulation

For the past year i have always been using latex swim caps that my swim team sells. But the swim caps they sell always last for around 1.5 years. So I want to buy a swim cap that lasts a long time and is good for swim meets and swim practice. Should I stay with latex swim caps or a different material?

Hello Lea!
Silicone caps do not tear as easily as latex. Silicone is a stronger material, therefore will last longer if properly taken care of.

My 7 year old daughter desperately needs a cap to protect her hair from the pool and salt water and I do not know what to buy. I need something that would keep her long hair from knotting up from the the water and goggles. If she could find a cap to keep her hair dry, even better. Please help a desperate mom who doesn't want to have to cut her swimmers lovely locks.

Hello Susan!
Since your daughter has long hair, you want to go with a silicone long hair swim cap (such as the Sporti Long Hair Silicone Swim Cap- product code 7535890). This will allow room for her hair in the cap while also providing a snug fit. It won't keep her hair completely dry (there is no such cap), but it will definitely help!

Hello all,

I'm a lifeguard and come into my local pool for a lap swim twice maybe three times a week. My hair is at a short to medium hair length. I've never worn a swim cap before, but I've noticed that my brown hair has begun to turn blonde at the ends and am thinking it's from the pool. What kind of cap would you recommend I use?

Thank you very much, much appreciated

I am having hair breakage along the faceline and starting behind ears. I just started wetting my hair and applying leavin conditioner before applying my cap. My cap is silicon (speedo). So is there a cap that would not pull on my hairline?
swimoutlet.com

Hi Nancy!
The best cap to use without pulling your hair is going to be a nylon/lycra cap. The only downfall to these is that they do not keep your hair dry at all. An option is the Sporti Nylon Spandex Swim Cap II. Another option would be a latex cap, these will still pull your hair a little but are not as tight as silicone caps are.

I'm a female and looking for my first dome/bullet cap because I recently qualified for a national level meet. Some of the girls on my team have women's ones. Do those really exist, or are they just L/XL dome caps? I've heard a rumor that there's a thin part where hair can go that settles at the nape of your neck? I prefer arena as a brand and I'm looking for a black one. Thanks!

Hi Joe, Silicone caps tend to last longer than latex. You can usually find these at your local sporting goods store, for example Dick's Sporting Goods or Big 5 Sporting Goods. Generally caps are available in kids or adult sizes as one size fits all.

Hi, looking for swim caps for my kids- ages 9 & 12 with medium amount hair. Thinking silicone... But is there a size that would work best for kids? Does the cap have extra space for hair? My 1 daughter does have kind of a lot. Thanks!
swimoutlet.com

Hi Heidi, we offer silicone caps specifically for long hair in adult size. There is extra space which allows long hair to be tucked inside the cap. The circumference of an adult sized cap is 20.1 inches. For example, Sporti Long Hair Silicone Swim Cap. If this is too large, then we offer Junior sized silicone caps (circumference 18.5 in) but these do not offer the extra space for longer hair. For example, Sporti Cartoon Clownfish Silicone Swim Cap Jr. It would be best to measure their head and compare to the adult and junior sizing for the best fit.
