Too loose and it slides off after two lengths. If you have long, thick, braided or loc’d hair, most standard caps simply do not have room. And almost everyone asks the same question: is there a swim cap that actually keeps hair dry?
This guide picks the best swim caps for lap swimming, long hair, braids and locs, and kids. We explain silicone vs latex vs lycra in plain English, show you how to put on a swim cap without pulling your hair, and give honest answers about keeping hair dry and protecting it from chlorine.

The best swim caps, reviewed

You need this if: you swim laps or take classes and want one durable, comfortable cap.
- MaterialSilicone
- FitStandard adult
- Best forShort to medium hair
- Rating4.2★ (30,000+ ratings)
Why we recommend it: Silicone lasts much longer than latex, pulls hair less and feels smooth in the water. With more than 30,000 ratings, this is one of the most trusted caps on Amazon, and buyers praise its quality and how well it works.
Keep in mind: Fit gets mixed reviews: some find it tight, others find it a little roomy. If you have long or thick hair, choose a long-hair or large cap instead.

- Material100% silicone
- FitTight, small
- UseEveryday training
- Rating4.2★ (25,000+ ratings)
Why we recommend it: A popular training cap with a close, hydrodynamic fit that keeps its stretch over time. Buyers mention quality and value, and it comes in lots of colors.
Keep in mind: Arena describes the fit as tight and small. People with bigger heads or lots of hair often find it too snug, and some say it does not keep hair dry.
TYR Long Hair Swim Cap
You need this if: you have long hair you wear in a bun or ponytail while swimming.
- MaterialWrinkle-free silicone
- ShapeExtra room at the back

Why we recommend it: The extra space at the back holds long hair without the cap creeping up your forehead. Buyers specifically praise how well it fits long hair and how easy it is to put on.
Keep in mind: Some buyers say water still gets in. A long-hair cap protects hair from most chlorine, but no cap keeps hair completely dry.
Large Swim Cap for Braids and Dreadlocks

- MaterialThick silicone
- FitRoomy, no scalp pressure
- Hair typesBraids, locs, weaves, curls

Why we recommend it: Standard caps squeeze voluminous hair and cause headaches. This cap is cut much larger so hair fits comfortably, and the thick silicone creates a snug seal. Buyers praise the quality, fit and comfort.
Keep in mind: Results on keeping hair dry are mixed. Tuck all hair in fully and press the edges flat to get the best seal.

Comparison table
| Cap | Best for | Fit | Rating |
|---|---|---|---|
| Speedo Silicone | Most swimmers | Standard | 4.2★ (30,000+) |
| Arena Classic | Training | Tight | 4.2★ (25,000+) |
| TYR Long Hair | Long hair | Roomy back | 4.2★ (6,100+) |
| Large cap | Braids, locs, thick hair | Very roomy | 4.2★ (12,700+) |
| Speedo Junior | Kids | Small | 4.2★ (3,400+) |
You may notice that ratings for swim caps are lower than for most sports gear. That is normal for this category: heads and hair vary so much that some buyers will always find a cap too tight or too loose. Choosing the right type for your hair matters more than the brand.
Silicone vs latex vs lycra swim caps
| Material | Pros | Cons | Best for |
|---|---|---|---|
| Silicone | Durable, smooth, pulls hair less, comfortable | Costs more than latex, a bit warmer | Most swimmers, long hair, daily training |
| Latex | Cheap, thin, light | Tears easily, can pull hair, not for latex allergies | Races, swim meets, spare caps |
| Lycra or fabric | Very comfortable, does not pull hair | Lets water through, more drag | Water aerobics, casual swimming, kids |
| Neoprene | Warm | Thick, costs more | Cold open water |
For most people, silicone is the best all-round choice. It lasts much longer than latex and is kinder to hair. Choose latex only if you want a cheap race-day cap and do not have a latex allergy.
Is there a swim cap that keeps hair dry?
Honestly, no swim cap keeps hair 100% dry, especially if you swim laps, dive or put your head underwater a lot. A good silicone cap that fits well keeps most water out and greatly reduces how much chlorine reaches your hair. To get as close to dry as possible:
- Choose silicone, not lycra.
- Pick the right size for your hair volume. A cap that is too tight lifts at the edges; too loose lets water flow in.
- Tuck every strand in, including around the ears and the nape of the neck.
- Press the edge of the cap flat against your forehead and neck.
- For extra protection, some swimmers wear two caps: a lycra cap underneath and a silicone cap on top.
How to put on a swim cap without pulling your hair
- Wet or condition your hair. Damp hair slides into a cap more easily, and conditioner reduces pulling.
- Tie long hair up. Put it in a low bun or plait, without sharp clips.
- Stretch the cap open. Put both hands inside, palms facing out, and stretch it wide.
- Start at the forehead. Place the front edge on your hairline, then pull the cap back over your head.
- Tuck in loose hair. Use your fingers to tuck stray hair around the ears and neck.
- Smooth it down. Make sure the edges sit flat and the cap covers the top of your ears or sits just above them, as you prefer.
▶ How to put on a swim cap for ladies that have long hairA short guide on putting on a swim cap with long hair. The video loads from YouTube only when you press play.
Best swim cap for long hair
Long hair needs extra room at the back of the cap. A long-hair cap like the TYR is shaped to hold a bun, so it stays on your forehead instead of slipping back. Tie your hair in a low bun before you put the cap on, because a high bun can push the cap off.
Best swim cap for braids, locs and natural hair
Braids, locs, weaves and thick natural hair need much more space than a standard cap provides. Large caps made for these styles prevent painful scalp pressure and make it possible to tuck all hair in. Measure your hair volume: if your hair is very full, some brands sell XL and XXL sizes. A satin scarf or lycra cap underneath can help hold hair in place before the silicone cap goes on.
Best swim cap for a big head
If standard caps feel tight across the forehead or give you a headache, try a long-hair or large cap, even if your hair is short. The extra room makes them more comfortable for larger heads. Avoid caps described as tight-fitting race caps.
Swim caps for kids
Many swim schools and clubs require caps, both to keep hair out of eyes and to keep pools cleaner. A junior silicone cap fits smaller heads best. For very young children who dislike tight caps, a lycra cap is more comfortable, though it lets more water through.
How to protect hair from chlorine
- Wet your hair with clean water before swimming. Hair that is already full of fresh water absorbs less chlorinated water.
- Apply a little leave-in conditioner before putting on your cap.
- Wear a well-fitting silicone cap.
- Rinse your hair with fresh water right after swimming and use a gentle shampoo.
- Regular swimmers may want a clarifying or swimmer’s shampoo once a week.
How to care for a swim cap
- Rinse it in cool fresh water after every swim.
- Let it air dry inside and out, away from direct sun.
- Dust latex caps with a little talc or cornstarch when dry so they do not stick together.
- Avoid sharp nails and hair clips when putting it on, because small tears grow quickly.
- Keep it away from heat, which weakens silicone and latex.
Do you need a swim cap?
You do not always need one, but there are good reasons to wear a cap: many public pools and swim clubs require them, they keep hair out of your eyes and goggles, they protect hair from chlorine, and they reduce drag for lap swimmers. In outdoor pools, a cap also shades your scalp a little from the sun. If you also need goggles, see our guides to the best anti-fog swim goggles and the best kids swim goggles.
