What is Period Swimwear & How Does It Work

Period swimwear is a kind of swimsuit with built-in absorbent layers. These innovative garments have three key components that work together to keep you comfortable and leak-free while enjoying water:

  1. Moisture-wicking layer: This layer closest to your skin is designed to wick away moisture and keep you feeling dry and comfortable. It’s like a personal lifeguard, ensuring you stay afloat in a sea of confidence during your period.
  2. Absorbent core: The real MVP of period swimwear, this layer traps and holds menstrual fluid, preventing it from leaking into the water. With varying absorbency levels, you can choose the swimwear that best matches your flow and be worry-free as you dive into the deep end.
  3. Waterproof barrier: The unsung hero of period swimwear, the waterproof barrier is the final layer that seals the deal, preventing any leaks from reaching the outer fabric. It’s like having your very own aquatic sidekick, keeping your secrets safe beneath the surface.

With these three layers working in perfect harmony, period swimwear ensures that you can take on any water challenge, even during that time of the month.

How Period Swimwear Avoids Soaking In Pool's Water

Period swimwear is specifically designed to prevent both leaks from getting out and pool water from getting in. It is achieved through the careful selection of materials and the unique construction of the swimwear. Here’s a closer look at why pool water won’t seep into the period swimwear’s layers:

  1. Water-resistant outer layer: Typically, the outer layer of period swimwear is made from a water-resistant fabric, such as polyester or nylon. This layer repels water and helps stop pool water from penetrating the swimwear.
  2. Tight-fitting design: Period swimwear fits snugly against the body, ensuring a secure seal that minimizes water intrusion. The close fit of the swimwear helps to maintain the effectiveness of the absorbent core and waterproof barrier.
  3. Waterproof barrier: The waterproof barrier of period swimwear is usually made from materials like polyurethane laminate (PUL) or thermoplastic polyurethane (TPU). These materials create an impenetrable barrier that guards off liquids, including pool water, from seeping through.
  4. Pressure and water flow: When submerged in water, the swimwear’s surface will get stronger pressure that keeps water from entering the absorbent layers. Additionally, the flow of water around the swimwear creates a path of least resistance, making it less likely for water to penetrate the layers.

While period swimwear will minimize the intrusion of pool water, choosing the right size and style is still essential to ensure a proper fit for optimal effectiveness. With the appropriate period swimwear, you can confidently enjoy swimming without worrying about pool water compromising the garment’s performance.
