We tested the Saalt Disc Duo on heavy flow days. See how it compares to cups, whether the two-pack is worth it, and get practical tips for leak-free wear.

If you have heavy flow days, you know the struggle: waking up to leaks, changing your cup or tampon more often than you'd like, and constantly worrying about stains. That's why we were excited to test the Saalt Disc Duo, a reusable disc two-pack designed for comfort and capacity. But is it really worth it for heavy flow? We put it to the test on our heaviest days to give you an honest review.

In this Saalt Disc Duo review, we'll cover how it works, how it compares to menstrual cups, and whether the two-pack is a smart investment. We'll also share practical tips for using a disc on heavy flow days, and how to care for it between uses.

What Is the Saalt Disc Duo?

The Saalt Disc Duo is a two-pack of reusable menstrual discs, designed to be worn internally during your period. Unlike a cup, a disc sits higher in the vaginal fornix, which can make it more comfortable for many people. The duo includes two sizes: one for average anatomy and one for those with a higher cervix or who need extra capacity. This is particularly useful for heavy flow days because you can choose the larger disc when you need more protection.

The discs are made from medical-grade silicone and are designed to be reused for up to 10 years with proper care. They are also free from BPA, latex, and dyes, making them a safe and eco-friendly choice. The two-pack comes in a reusable storage tin, which is great for travel or keeping one at home and one in your bag.

  • Two sizes included: one for average anatomy, one for higher cervix or heavier flow
  • Medical-grade silicone, reusable up to 10 years
  • BPA-free, latex-free, and dye-free

How Does It Perform on Heavy Flow Days?

We tested the Saalt Disc Duo during our heaviest days, and we were impressed. The larger disc held a significant amount of fluid, and we experienced no leaks for up to 12 hours, which is the recommended wear time. The disc's capacity is comparable to two super tampons, making it a great option for heavy flow.

One of the standout features is the auto-dump ability: when you use the bathroom, you can contract your pelvic floor muscles to partially empty the disc without removing it. This extends the wear time even further, which is a game-changer for heavy flow days. However, it's important to practice this technique before relying on it, as it can be tricky at first.

  • Holds up to 2 super tampons' worth of fluid
  • Auto-dump feature for longer wear without removal
  • No leaks in our 12-hour test

Saalt Disc vs. Cup: Which Is Better for Heavy Flow?

If you're comparing the Saalt Disc to a menstrual cup, there are a few key differences. Cups are often more familiar and can be easier to insert for beginners. However, discs can be more comfortable for those with a sensitive bladder or a low cervix, and they may be easier to insert and remove because they don't rely on suction.

For heavy flow, both cups and discs can work well, but discs have a few advantages. The auto-dump feature is unique to discs and can be a lifesaver on heavy days. Additionally, discs are often more comfortable during sleep because they don't put pressure on the cervix. That said, cups may have a higher capacity in some cases, so it's a matter of personal preference. If you're new to reusable period care, you might want to try a cup like the Saalt Soft Duo Pack first, then graduate to a disc.

  • Discs rely on a seal, not suction, which can be more comfortable
  • Auto-dump feature is exclusive to discs
  • Cups may have higher capacity in some models

Is the Two-Pack Worth It?

The Saalt Disc Duo is priced higher than a single disc, but when you consider that you get two sizes, it's a great value. The two-pack ensures you have the right fit for your anatomy, which is crucial for leak-free wear. It also gives you a backup disc when one is being washed or if you're traveling.

For heavy flow days, having the larger disc is essential, and the smaller one can be used on lighter days or as a backup. This versatility makes the two-pack a smart investment for anyone with a heavy flow. Plus, the discs come with a storage tin, which is a nice touch. If you're looking for a period disc that can handle heavy flow, the Saalt Disc Duo is definitely worth considering.

  • Two sizes ensure a proper fit for your anatomy
  • Backup disc for travel or when washing
  • Includes a reusable storage tin

Tips for Using a Disc on Heavy Flow Days

To get the most out of your Saalt Disc Duo, here are some tips we learned during our testing. First, make sure you insert it correctly: fold the disc in half, push it back and down, and tuck the rim behind your pubic bone. It should sit low enough that you can feel it with your fingertip but not so low that it causes discomfort.

Second, practice the auto-dump technique before you need it. When you sit on the toilet, bear down as if you're having a bowel movement, and the disc will tilt and release some fluid. This takes a bit of practice, but once you get it, you can go longer between removals. Finally, clean your disc with a gentle wash like the Saalt Cup Wash to keep it hygienic and extend its lifespan.

  • Insert correctly: fold, push back, tuck behind pubic bone
  • Practice auto-dump at home before relying on it
  • Use a dedicated wash to keep your disc clean

Our Verdict: Is the Saalt Disc Duo Right for You?

After testing the Saalt Disc Duo on heavy flow days, we can confidently say it's a top contender for the best period disc for heavy flow. It offers excellent capacity, comfort, and the convenience of a two-pack. The auto-dump feature is a game-changer, and the fact that it's reusable makes it an eco-friendly choice.

If you're new to discs, you might want to start with a single disc to see if it's for you. But if you're ready to commit to reusable period care and want a reliable option for heavy days, the Saalt Disc Duo is worth the investment. It's also a great option for those who want to reduce waste and save money in the long run.

  • Excellent capacity and comfort for heavy flow
  • Auto-dump feature extends wear time
  • Reusable and eco-friendly

Overall, the Saalt Disc Duo is a fantastic choice for anyone with heavy flow days. Its two sizes, high capacity, and auto-dump feature make it stand out from other period discs. If you're ready to make the switch to reusable period care, we highly recommend giving the Saalt Disc Duo a try. And if you're still exploring options, don't forget to check out the Saalt Soft Duo Pack for a cup alternative that might also suit your needs.
