Can you swim in period underwear?
Here's What You Need to Know Before Diving In
If you love the freedom and eco-friendliness of period underwear, you might be wondering:
👉 “Can I wear period underwear while swimming?”
The short answer is:
No, regular period underwear is not designed for swimming.
But—there are swim-specific options for your period. Let's break it down.
🩲 What Is Period Underwear?
Period underwear is made with absorbent, moisture-wicking layers designed to:
-
Soak up menstrual blood
-
Prevent leaks during everyday activities
-
Replace or back up tampons, pads, or menstrual cups
However, these layers are not waterproof, and most standard styles (like those from NYX Collection) will absorb water from the pool or ocean—not just your menstrual flow.
🌊 So, Can You Swim in Regular Period Underwear?
No. Regular period panties:
-
Are not water-resistant
-
Will soak up pool or seawater
-
May feel heavy, soggy, and uncomfortable
-
Can’t trap menstrual flow underwater effectively
🩱 What to Wear Instead: Period Swimwear
For swimming during your period, look for period swimwear, which is:
-
Designed with water-resistant outer layers
-
Built to contain menstrual flow while preventing water from entering
-
Available as swimsuits, bikini bottoms, or one-pieces
🛍️ Brands like Modibodi, Ruby Love, and Knix offer stylish period swimwear options.
🛑 Can You Swim with a Tampon or Menstrual Cup Instead?
Yes! Both are great for swimming:
-
Tampons: Compact, easy to use, and won’t absorb water from outside
-
Menstrual Cups/Discs: Reusable, long-lasting, and excellent for leak protection while swimming
✅ Final Recommendation
If you plan to swim during your period:
-
Skip regular period underwear
-
Choose period swimwear or wear a tampon, menstrual cup, or disc
-
Use a towel or dry period underwear to change into afterward
