Best swim cap for pool and open water: Amazon picks

Swim cap material (silicone versus latex versus lycra), whether it is hydrodynamic, how much hair it can contain, durability with daily chlorine exposure and whether the cap is for competitive or recreational swimming determine which swim cap performs in the water.

By Pickspry EditorialUpdated September 28, 20264 picks

The short answer

Speedo Silicone Solid Swim Cap at $12 is the best swim cap for most swimmers: the silicone material resists chlorine degradation longer than latex, the smooth outer surface creates less drag than textured caps and the silicone stretches to fit most adult head sizes without the tight pressure of latex that some swimmers find uncomfortable.

Best swim cap for most swimmers

Speedo Silicone Solid Swim Cap

Brand: Speedo

Best for

Daily lap swimmers and recreational pool users who want a durable silicone cap that holds up to regular chlorine exposure and provides a comfortable, non-restrictive fit for short to medium hair, where Speedo Silicone Solid uses a thick silicone construction that resists the cracking and degradation that affect latex caps with daily pool use.

Skip if

Long, thick or voluminous hair that cannot fit in a standard cap is the case. Speedo Silicone Solid is sized for average adult heads with short to medium hair. Swimmers with long hair, braids, locs or very thick hair require a larger swim cap designed to accommodate more hair volume (Aegend long hair cap, stretch material caps).

Check price on Amazon

Speedo Silicone Solid uses a solid color, smooth-surface silicone construction. Silicone resists chlorine degradation significantly longer than latex, providing 12 to 24 months of daily pool use before the material begins to thin and tear, compared to latex which may degrade in 3 to 6 months of daily chlorine exposure. The smooth outer surface reduces water resistance compared to the textured surface of some caps.

Speedo is the world's leading competitive swimwear brand. The Silicone Solid is their standard lap swimming cap, available in multiple colors. The cap pulls on and removes easily without pulling hair.

At $12, Speedo Silicone Solid is the mid-price quality option in this guide.

Best budget swim cap

TYR Latex Swim Cap

Brand: TYR

Best for

Budget-conscious swimmers who want a functional swim cap for occasional pool use at the lowest cost, where TYR Latex cap uses a standard latex construction that performs adequately for swimming while being significantly less expensive than silicone caps.

Skip if

Daily training use over multiple months is the goal. Latex swim caps degrade faster than silicone under daily chlorine exposure, typically showing cracks and thin spots within 3 to 6 months of daily use compared to 12 to 24 months for silicone. For swimmers who train daily, the longer lifespan of silicone justifies the higher initial cost. Also, users with latex allergies should not use latex swim caps.

Check price on Amazon

TYR Latex swim cap uses a standard latex construction in a thin, form-fitting design. Latex caps fit more tightly against the head than silicone and may create more pressure at the temples for some swimmers. The thin latex material has less hydrodynamic drag than silicone due to the tighter fit but is more prone to tearing during application, particularly when pulled over ears or jewelry.

TYR is a competitive swim brand that produces latex caps as an entry-level option alongside their higher-performance silicone and bubble-textured caps. The low price makes latex caps practical to replace frequently.

At $5, TYR Latex is the most affordable cap in this guide.

Best swim cap for long hair

Aegend Long Hair Swim Cap Extra Large Silicone

Brand: Aegend

Best for

Swimmers with long hair, thick hair, braids, locs or dreadlocks who cannot fit their hair into a standard-size swim cap, where Aegend Long Hair uses an extra-large silicone design with more volume in the cap dome to accommodate more hair mass than standard caps.

Skip if

Short or medium hair is the case. Aegend Long Hair cap is designed for extra hair volume and will appear baggy and loose on swimmers with short or average-length hair, which creates more water resistance than a snug-fitting standard cap. Swimmers with short to medium hair should use a standard-sized cap (Speedo Silicone Solid) that fits close to the head.

Check price on Amazon

Aegend Long Hair cap uses a wider dome construction with more interior volume than standard caps to accommodate long ponytails, braids and thick hair without the extreme stretching and tension that standard caps create when forced over large hair volumes. The silicone material still provides chlorine resistance and a smooth outer surface.

The cap accommodates hair bunched at the crown of the head rather than requiring hair to be fully flattened against the skull. Available in multiple colors.

At $10, Aegend Long Hair is the best value for swimmers who need extra-large cap volume.

Best competition swim cap

Arena Silicone Swim Cap Standard

Brand: Arena

Best for

Competitive swimmers who want a competition-quality silicone cap from a leading race swimwear brand for both training and competition use, where Arena Silicone Cap uses a slightly thinner silicone than standard training caps for a smoother, more hydrodynamic fit on the head during race-pace swimming.

Skip if

Maximum durability for daily training is the priority. Arena silicone competition cap uses a thinner silicone that provides a sleeker fit but may not last as long as thicker training caps under daily pool use. For swimmers who train daily and prioritize cap longevity over hydrodynamic optimization, the Speedo Silicone Solid with thicker silicone provides longer service life.

Check price on Amazon

Arena Silicone Swim Cap uses a smooth silicone construction with a slightly thinner profile than standard training caps for a closer fit on the head. The cap is appropriate for both training and competition use and carries the Arena brand recognition in competitive swimming environments.

Arena is the second-largest competitive swimwear brand globally after Speedo. The silicone cap is worn by Arena-sponsored swimmers at competition and is available in team colors for club swimming.

Questions people ask

How do I put on a swim cap without pulling my hair?

Putting on a swim cap without hair pulling requires a systematic technique. Start by gathering all hair up and holding it at the top of the head with one hand. With the other hand, stretch the front of the cap over the forehead from front to back, centering it above the eyebrows. Then use both hands to stretch the back of the cap over the back of the head while tucking in any loose strands with a finger. For silicone caps, avoid stretching with fingernails that can puncture the material. Wetting hair slightly before putting on the cap reduces friction between hair and the cap interior. For swimmers with long hair, putting hair in a high bun before stretching the cap over the bun reduces the force required to pull the cap down over the full hair length.

Does a swim cap keep hair dry?

Standard swim caps do not keep hair fully dry. Swim caps are designed to reduce water resistance and keep loose hair from spreading in the water, not to create a waterproof seal around the head. Water enters around the edges of the cap during diving and swimming. Hair inside the cap still gets wet from humidity and minor water seepage. Specialized neoprene or coated fabric swim caps marketed as waterproof provide better water exclusion but are not completely waterproof. For swimmers concerned about chlorine damage to hair, applying a hair conditioner or coconut oil to hair before putting on the cap provides more protection against chlorine absorption than the cap alone.

How long does a swim cap last?

Silicone swim caps last 12 to 24 months with regular daily pool use. Latex swim caps last 3 to 6 months with daily pool use before the material begins to crack or thin. The primary cause of cap degradation is chlorine exposure, heat (avoid leaving caps in hot cars), stretching damage during application and UV exposure for outdoor use. Extend cap life by rinsing in clean water after each pool use to remove chlorine residue, then allowing to dry completely before storage. Store silicone and latex caps away from direct sunlight and heat. Caps that develop thin spots, cracks or sticky areas should be replaced, as these indicate material degradation that will lead to tearing during use.
