Period Underwear vs. Menstrual Cups: Which Is Right for You?
Both are reusable, eco-friendly alternatives to disposables. We compare comfort, capacity, cost, and convenience.
Period underwear and menstrual cups are the two most popular reusable period products. They serve the same goal — reducing waste — but work very differently.
Menstrual cups are inserted internally and collect blood. They hold the most fluid — typically 15-30ml, compared to 2 tampons' worth for most period underwear. You can wear a cup for up to 12 hours, making it ideal for workdays and overnight.
Period underwear is worn like regular underwear with absorbent layers built in. It's easier to use — no learning curve like with cups. Great for light days, backup protection, or people who prefer external products.
Cost comparison: A good menstrual cup costs $25-35 and lasts up to 10 years. Period underwear costs $30-40 per pair and lasts 2-3 years with proper care. For heavy flow, many people use both: cup for primary protection, underwear as backup.
Our recommendation: Start with period underwear if you're new to reusables. Once comfortable, try a cup for heavy days. The combination gives you maximum protection with minimum waste.
