Why Choose Sustainable Period Products?

The average person uses thousands of disposable tampons and pads over a lifetime, most of which end up in landfills or oceans. Sustainable period products like menstrual discs and cups are reusable, reducing waste significantly. They are also free from the chemicals and synthetic materials found in many conventional products, making them a healthier choice for your body.

Flex products are designed with both comfort and sustainability in mind. The Flex Disc, for example, is a disposable option that uses plant-based materials, while the Flex Cup is fully reusable. By choosing these products, you're not only reducing your environmental footprint but also investing in period care that works with your body's natural anatomy.

  • Reusable products save money over time and reduce waste.
  • Plant-based and medical-grade materials are gentler on sensitive skin.
  • Flex products are designed to be mess-free and comfortable for all-day wear.

Understanding Your Flow: Disc vs. Cup vs. Liners

The first step in choosing the right product is understanding your menstrual flow. Menstrual discs like the Flex Disc sit at the base of the cervix and can hold more fluid than a tampon, making them ideal for heavy days. They also allow for mess-free period sex—a unique benefit that cups don't offer.

The Flex Cup is a reusable silicone cup that collects fluid rather than absorbing it. It's a great choice for those who prefer a set-and-forget option that can be worn for up to 12 hours. For lighter days or as a backup to a disc or cup, Flex Daily Liners provide gentle, breathable protection that's perfect for everyday freshness.

If you're new to sustainable period care, consider starting with a starter bundle that includes both a disc and liners, so you can experiment and find what works best for you.

  • Heavy flow: Opt for a menstrual disc for higher capacity.
  • Long wear: The Flex Cup offers up to 12 hours of protection.
  • Light days: Use Flex Daily Liners for comfortable, breathable coverage.

How to Choose the Right Menstrual Disc

Choosing the right menstrual disc depends on your anatomy and comfort. The Flex Disc is designed with a unique removal loop that makes it easier to take out than traditional discs. It's available in one size that fits most, but if you're between sizes or have a high cervix, you might need to try a different angle or consult with your healthcare provider.

For those who prefer a disposable option, the Flex Plant+ Disc is made from plant-based materials and is fully flushable. It's a great eco-friendly alternative to traditional tampons and pads, especially for travel or on-the-go use. If you're looking for a reusable option, the Flex Cup is made from medical-grade silicone and can last for years with proper care.

  • Consider your cervix height: discs sit lower than cups.
  • Try the Flex Disc for mess-free period sex.
  • The Flex Plant+ Disc is perfect for travel—flushable and plant-based.

Accessories and Extras to Complete Your Routine

Once you've chosen your main period product, consider adding accessories to make your routine even easier. The Flex Disc Case and Flex Cup Case are perfect for carrying your reusable products discreetly in your bag. The Softcup Case is another option for storing your disc safely.

For hygiene on the go, Flex Wipes are individually wrapped, biodegradable wipes that are gentle on sensitive skin. They're great for freshening up during your period or after using the bathroom. And if you're looking for a touch of style, the Haus of Uterati Bandana is an organic cotton bandana that can be used as a stylish accessory or a reusable wrap.

Many of these extras are included in Flex bundles, which offer a complete starter kit at a discounted price. Bundles are a great way to try multiple products and find your perfect routine without committing to full-size purchases.

  • Use a case to keep your disc or cup clean and protected.
  • Flex Wipes are perfect for on-the-go freshness.
  • Bundles save money and let you try multiple products.

Where to Start: Flex Starter Bundles

If you're ready to make the switch, the Flex Starter Bundle is the perfect entry point. It includes a Flex Disc or Flex Cup, a supply of Flex Daily Liners, and a case to store your product. This bundle gives you everything you need to try sustainable period care without guesswork.

For those who want to go all-in, the Flex Complete Bundle includes both the disc and the cup, plus liners and wipes, so you can switch between products based on your flow and activities. This is ideal for people who want maximum flexibility and convenience.

Remember, the right product is the one that fits your body and lifestyle. Don't be afraid to experiment—many people find that they prefer different products for different days of their cycle.

  • Start with a bundle to save money and try multiple products.
  • Consider your lifestyle: travel, sports, and sleep all affect your choice.
  • Read user reviews to learn from others' experiences.

Choosing sustainable period products is a personal journey, but with the right information, you can find the perfect fit. Flex offers a range of high-quality, eco-friendly options that cater to different needs and preferences. Whether you start with a starter bundle or pick individual items, you'll be taking a positive step for your health and the planet.
