Quick Answer

To prevent leaks in period swimwear, choose the right absorbency for your flow, ensure a snug fit, and avoid sitting in wet swimwear for long periods. For heavy days, opt for high-absorbency styles or pair with a tampon for backup.

Swimming on your period used to mean bulky pads or skipping the pool altogether. But with modern leak-proof period swimwear, you can dive in with confidence. The key is understanding how these suits work and how to use them correctly to avoid embarrassing leaks.

Unlike regular swimwear, period swimwear features built-in absorbent layers that trap menstrual fluid while you're in the water. However, they're not all the same, and knowing what to look for can make all the difference between a carefree swim and a stressful one.

Understanding Absorbency Levels

Period swimwear comes in different absorbency levels, typically measured in milliliters (ml). Light absorbency (around 20 ml) suits the start or end of your period or 'just in case' days. Moderate to heavy absorbency handles more substantial flow. For example, Modibodi's Ultra-Leak Proof line absorbs up to 250 ml, making it suitable for serious leaks.

Choosing the wrong absorbency is a common cause of leaks. If your flow is heavy and you choose a light-absorbency suit, it may overflow. Conversely, using high absorbency when you don't need it can be unnecessary. Match the absorbency to your expected flow for the time you'll be swimming.

  • Check the absorbency rating before buying.
  • Consider your flow intensity for that day.
  • When in doubt, size up in absorbency for peace of mind.

Getting the Right Fit

A snug fit is crucial for preventing leaks. Gaps or loose areas can allow water to enter and reduce the effectiveness of the leak-proof barrier. Look for styles with adjustable features like side ties or straps to customize the fit.

For active swimming, choose a style that stays in place. One-piece suits with adjustable straps, like the Swimwear String Back One Piece, offer a secure fit. High-waisted briefs or bikini bottoms with ruched sides also provide good coverage and adjustability.

  • Try on swimwear and move around to test the fit.
  • Adjust ties and straps for a snug but comfortable feel.
  • Avoid styles that ride up or shift during movement.

Caring for Your Period Swimwear

Proper care extends the life of your period swimwear and maintains its leak-proof properties. Rinse your swimwear in cold water immediately after swimming to remove chlorine, salt, and any menstrual fluid. Avoid wringing or twisting the fabric.

Wash with a gentle detergent and air dry away from direct sunlight. Do not put period swimwear in the dryer, as heat can damage the absorbent layers. Following the care instructions on the label ensures your swimwear continues to perform.

  • Rinse in cold water after each use.
  • Hand wash with mild soap.
  • Air dry only.

When to Use Backup Protection

On heavy flow days, even the most absorbent period swimwear might not be enough for extended swimming sessions. Consider using a tampon or menstrual cup as backup, especially if you plan to be in the water for more than a couple of hours.

Alternatively, schedule swimming for lighter days of your period. If you're unsure about your flow, bring a change of clothes and extra protection. The goal is to enjoy your swim without anxiety, so do what makes you feel most comfortable.

  • Use backup protection for heavy days.
  • Take breaks to check and empty if needed.
  • Have a plan for changing after swimming.

Diagnosing and Fixing Leaks

  • Symptom: Leak at the leg openings: This often indicates a loose fit or insufficient absorbency coverage in that area. Try a smaller size or a style with tighter leg elastics. If leaks persist, consider a higher absorbency.
  • Symptom: Leak after sitting in wet swimwear: Prolonged sitting can cause water to push fluid out. The absorbent layer may be saturated. Take breaks to rinse and change if needed. For long sessions, use backup protection.
  • Symptom: Leak during heavy flow days: The absorbency level may be too low for your flow intensity. Opt for a style with higher absorbency, like Modibodi's Ultra-Leak Proof line, or combine with a tampon.
