After a year and a half of rigorous testing and countless iterations, we arrived at the perfect fabric blend for our Cooch period undies. We originally dreamed of using 100% bamboo for its natural softness, breathability, and antibacterial properties—qualities we value so highly. However, while bamboo is ideal for everyday comfort, it couldn’t meet the demands of reliable period protection on its own. To bridge that gap, we carefully blended in a small amount of high-quality synthetic polyester certified by Oeko-Tex, enhancing durability, absorbency, and leak resistance. In our commitment to balance, we believe this thoughtful mix not only provides a safer, more reliable alternative to disposable products but also offers a more comfortable option than traditional menstrual cups.

Here’s a detailed breakdown of each layer in our design:

• Body of the Undie (95% Bamboo, 5% Spandex):

This foundational layer delivers the natural softness, breathability, and antibacterial benefits of bamboo, while the spandex adds the flexibility and shape retention needed for everyday wear.

• Top Gusset Lining (50% Bamboo, 50% Polyester):

In direct contact with your skin, this blend offers a gentle, hypoallergenic surface from bamboo combined with the durability and moisture management of polyester, reducing the risk of chafing.

• Middle Layer (80% Polyester, 20% Nylon):

Serving as the absorbent core, this layer excels at moisture-wicking and quick-drying with its high polyester content, while nylon contributes additional strength and durability to lock in fluids effectively.

• Layer 3: Breathable PUL:

The outermost layer features a breathable polyurethane laminate that acts as a leak-proof barrier. It allows moisture vapor to escape while preventing any fluid from seeping through, providing the final line of defense in our multi-layer approach.

This meticulously chosen combination of fabrics ensures that our period undies deliver both unparalleled comfort and high performance during your cycle.

Our unique layer technology is designed for ultimate comfort, absorbency, and leak protection. Each pair of Cooch period underwear features a moisture-wicking top layer to keep you feeling dry, an ultra absorbent core to lock in fluid, and a leak resistant barrier for extra security.

It took a year and a half of trial and error to perfect our design. We tested multiple gusset styles, endured plenty of embarrassing leaks, and refined every detail until we found the perfect blend for ultimate protection.

Caring for your Cooch period underwear is easy. Simply rinse them in cold water after use, then machine wash on a gentle cycle with mild detergent. Avoid using fabric softeners or bleach, as these can affect the absorbency. Hang dry or lay flat to preserve the integrity of the fabric and elastic.

The duration you can wear your Cooch period underwear depends on your flow. Generally, you can wear them from 6 - 10 hours, but it's always best to monitor your comfort and change as needed. For heavier flow days, you may need to change more frequently.

Yes, our Revie Shorty is specifically designed for overnight use, holding 3-4 tampons worth of flow to keep you protected and comfortable throughout the night. The high-waist Vallie Panty is also a great option for added coverage and security during sleep.

Absolutely! Cooch period undies are reusable and designed to last for many cycles with proper care. This makes them a sustainable and cost-effective alternative to disposable period products.

Yes, you can wear Cooch period underwear alongside other menstrual products like tampons or menstrual cups for added protection and peace of mind, especially on your heaviest days.
