Why Period Underwear Is Worth Trying

Unlike traditional sanitary napkins or tampons, period underwear absorbs menstrual flow directly, eliminating the need for pads, plastic waste and any last-minute pharmacy runs. The fabric is engineered with multiple layers to absorb and lock in moisture, keeping you dry and odor-free. Some of the other benefits include that it’s:

• Cost-effective: One pair can last for years with proper care.
• Stylish: Many Japanese brands design their products to resemble everyday underwear in terms of both appearance and feel.
• Confidence Boosting: With the ability to move freely, whether you’re at yoga, at work or exploring around.

Still, it’s not a one-size-fits-all fix. Period underwear works best when matched to your flow level. Lighter days may require just the underwear itself, while heavier days may still necessitate an extra liner or pad.

Absorbent vs. Sanitary

Not all period underwear is created equal. In Japan, there are two main types you’ll want to know:

Absorbent (Reusable) Shorts

• Purpose: Designed to absorb menstrual flow directly, meaning no pad or tampon is needed.
• Features: Multi-layer fabrics that lock in moisture, prevent leaks and often include odor-control technology.
• Best for: Everyday wear, traveling, or overnight use, depending on your desired level of absorbency.

Sanitary (Pad-Compatible) Shorts

• Purpose: Worn with a pad for extra protection, helping prevent leaks or stains.
• Features: Waterproof lining, soft fabrics such as cotton or silk, and designs that facilitate easy and secure pad placement.
• Best for: Heavy-duty day or nighttime use, or anyone transitioning to reusable underwear.

If you’re new to reusable menstrual underwear, here are some Savvy-approved tips to help you find your perfect match:

• Match absorbency to your flow: Use high-absorbency types for heavy days or overnight.
• Check the materials: Opt for breathable cotton blends to help prevent irritation.
• Start small: Try one pair before investing in multiple (period underwear might not be for everyone).
• Mind your laundry: Rinse in cold water and avoid softeners or bleach to maintain performance.
• Mix and match: You can always add a pad or liner if you need that extra reassurance.

Period underwear in Japan isn’t just about practicality; it’s about empowerment. The Japanese brands above prove that comfort, sustainability and style can absolutely coexist—even on your heaviest day. So go ahead and add a pair (or two) to your drawer. Your cycle (and the planet) will thank you!
