Period swim pants (or period swimsuits) work by using specialized fabric technology to absorb menstrual blood while repelling pool or ocean water. The outer layer is water-repellent to prevent water absorption, and the inner layers are absorbent to trap period blood. They are best suited for light flow days or as a backup to other period products.
Here's a breakdown of how they function:
- Water-Repellent Outer Layer: This layer is crucial for keeping external water out. It's usually made of a synthetic material treated to resist water penetration. This prevents the swimsuit from becoming waterlogged and heavy.
- Absorbent Inner Layers: These layers are designed to quickly absorb and lock away menstrual blood. The materials used are similar to those found in reusable period pads, often including fabrics like:
- Microfiber: For rapid absorption.
- Bamboo: For its absorbent and antibacterial properties.
- Cotton: A natural and absorbent fiber.
- Leak-Proof Barrier: Some period swim pants also include a leak-proof layer for extra protection against leaks.
Key Functionality:
- Water Repellency: The outer fabric prevents pool or sea water from saturating the absorbent core.
- Blood Absorption: The inner layers effectively trap menstrual blood.
- Comfort and Discretion: Designed to look and feel like regular swimwear.
Limitations:
- Flow Capacity: Most period swim pants are designed for light to moderate flow. They may not be suitable for heavy period days.
- Backup Option: Some people use them as a backup to tampons or menstrual cups for added security.
- Rinsing: After swimming, it's important to rinse the swimsuit to remove chlorine or salt water and any excess blood.
In essence, period swim pants allow you to swim comfortably and confidently during light flow days by using a combination of water-repellent and absorbent materials.
