Quick Comparison Snapshot

This snapshot offers a side-by-side look at the core features that matter most, helping you quickly identify the similarities and distinctions between these popular menstrual cups.

Why Cup Firmness Matters

When comparing menstrual cups like the Saalt and Diva Cup, one of the most overlooked—but critical—features is cup firmness. Why does this matter? The firmness of your menstrual cup can dramatically affect your comfort, the effectiveness of your cup, and even how easy it is to use on a day-to-day basis.

A firmer cup like the Diva Cup or original Saalt Cup opens more easily inside the vagina, which means it can form a reliable seal, reduce leaks and give you peace of mind whether you're running errands or nailing a yoga pose. Firmer cups also tend to withstand stronger pelvic floor muscles, so they’re a reliable pick for athletes and people who want to stay active. On the flip side, if the cup is too firm, it may press against the bladder, vaginal walls, or cervix, causing discomfort—especially for those who are postpartum, have a sensitive urethra, or experience bladder leaks.

A softer cup, like the Saalt Soft Cup, bends and molds more easily to the vaginal canal, often making it the go-to choice for those with sensitivities or anyone newer to menstrual cups. For postpartum individuals or those prone to bladder irritation, a softer cup can feel gentler, especially during long days or overnight use. However, softer cups sometimes require extra finesse when inserting or making sure they’re fully opened, since they can be trickier to pop into place and seal correctly.

In the end, firmness isn’t just a technical detail—it can be the difference between loving your menstrual cup experience or giving up on it entirely. Knowing your body and preferences is crucial for finding the cup that will fit seamlessly into your routine, whether you’re tackling new adventures or simply looking for leakproof confidence.

Comfort Test: All-Day Wear Experience

When it comes to menstrual cups, comfort is key. You want to forget you’re wearing one—no pinching, poking, or discomfort. How do popular menstrual cup options hold up for all-day wear? Here’s an honest look at what it feels like from morning to night.

First Impressions Matter

Most leading cups use medical-grade silicone, but differences in texture and flexibility matter. Softer cups tend to mold easily to your body, making them a top pick for those with a low cervix, sensitive bladder, or prone to cramping. Firmer period cups can be easier for beginners since they pop open reliably, but they can cause pressure on sensitive vaginal walls, especially with extended wear.

Moving Through Your Day

Activities like working, exercising, or running errands should be leak- and worry-free. Many users report that softer cups provide a ‘barely-there’ feel during movement—important for comfort across many hours. Firmer cups are very secure, but can sometimes be more noticeable, especially for those sensitive to internal pressure.

Stem and Rim Design

Don’t overlook stem length and thickness. The Diva Cup has a V-cup design with a short stem (ideal for people with a medium to high cervix), while the Saalt Cup has a bulb design with a longer stem that can be trimmed to the desired length. The Diva Cup is held in place solely by its firm rim, while the Saalt Cup is held in place by both the rim and the bulb of the cup. Rim design is important: a thinner, flexible rim generally means less pressure and more comfort throughout the day.

Dryness & Breathability

Proper suction and breathability stop leaks without causing dryness or irritation. Softer cups tend to create gentle suction, which many find ideal if they are prone to vaginal dryness, cramping, or postpartum.

In the end, all-day comfort comes down to your body’s needs. Cup flexibility, stem style, and rim design all influence how good you’ll feel from sunrise to sunset. It’s okay to try different styles to find a cup that feels just right—so you can get on with your day in total comfort.

Seal Strength and Leak Protection

Choosing a menstrual cup often comes down to how reliably it seals and protects against leaks. Both Saalt and Diva Cup are designed with leak prevention in mind, but their main differences lie in their material and flexibility.

The Diva Cup features a firmer silicone, which tends to “pop” open easily and form a solid seal—ideal for those with strong pelvic floor muscles or who want extra security. However, this firmness can sometimes feel uncomfortable for those with sensitivities, vaginal tenderness, or postpartum changes. The rim of the Diva Cup, due to its V-shape, is what secures the cup in place. 

The Saalt Cup comes in two firmness levels, both original and soft. Both the rim and the bulb of the Saalt Cup design provide points of contact on the vaginal walls to keep the cup in place. The balanced nature of both bulb and rim security offers a comfortable and leak-free fit. Softer cups, like the Saalt Soft Cup, offer more flexibility and gently mold to a wider range of body shapes. This can result in a more comfortable fit and an equally effective seal, especially for beginners or individuals who have experienced pressure with firmer cups. Softer cups also tend to be more forgiving during your body’s natural changes, such as after childbirth or with age. The Saalt Teen Cup, a smaller entry-level cup, is ideal for beginners or those with a low cervix. 

Proper insertion affects seal strength for both brands. Ensuring the rim fully opens and runs smoothly along the vaginal wall is crucial for leak protection. Features like subtle ridges or gripped stems on some cups help with adjustments and make them easier to use, especially for newcomers. Learn: how to insert a menstrual cup. 

In the end, choosing between Saalt and Diva Cup comes down to your personal anatomy and comfort preferences. A good seal equals reliable, all-day leak protection—giving you the confidence to take on whatever your day brings.

Learning Curve: Beginner Friendliness

Trying a menstrual cup for the first time can be intimidating. Folding, inserting, and removing a silicone cup is a different experience compared to traditional period products, so beginner friendliness is key.

The Diva Cup, a pioneer in menstrual cups, features a firmer silicone and conical (elongated) shape that helps it pop open once inserted, which can be reassuring for first-timers concerned about leaks. However, this firmness can make you more aware of its presence, especially if you’re sensitive or have a lower cervix. Some users also find sealing and removal tricky at first.

In contrast, softer menstrual cups may feel gentler and more comfortable, though they require more effort to ensure they fully open and form a leak-proof seal. Many brands offer various sizes and helpful guides, making the adjustment period smoother. Customer support resources are invaluable during those initial, uncertain cycles.

Regardless of brand, most newbies need a couple of cycles to get comfortable. Expect a period of trial and error—finding the right fold, insertion angle, and removal technique takes patience. Fortunately, millions have successfully switched to menstrual cups and now appreciate the eco-friendly and economical advantages they offer.

With a little practice and the right product, the learning curve is manageable. If you’re considering making the change, know that confidence and comfort grow quickly with experience—making menstrual cups a solid option for period care.

Cup Capacity for Heavy Flow Days

When your period is at its peak, the last thing you want is worry about leaks and constant bathroom trips. That’s where understanding menstrual cup capacity really matters. Both the Saalt Cup and the Diva Cup are designed to offer all-day comfort and protection, but the fine print can make a big difference—especially for those who experience heavy flow days.

Menstrual cup capacity typically ranges from about 15 mL to 30 mL, depending on the size and brand. Standard Diva Cup sizes hold approximately 26 mL in their Model 1 (for lighter to moderate flow), while Model 2 bumps that up to about 30 mL for those with heavier needs. Saalt size Small Cup holds 25 mL fluid, while the Saalt Regular size holds up to 30 mL fluid in both the soft cup and original firmness options. The Saalt Teen Cup holds up to 15 mL fluid, and is a great option for people new to inserted products, or those with a low cervix. Other brands offer similar sizing splits, with their larger versions hovering around the 30 mL mark. This may sound like a small difference, but it can mean an extra hour or two before needing to empty the cup—a game changer for long days at work, overnight wear, or when you’re on the go. Ever wondered how to find your cervix? Here’s a great tutorial showing how to find your cervix height. Understanding your internal anatomy is a key factor in success with menstrual cups and menstrual discs. 

Keep in mind: a higher capacity doesn’t mean you have to sacrifice comfort. Most menstrual cups are designed so that even their larger sizes remain flexible and easy to insert. It’s about matching your cup size and firmness to your body and your flow. If you find yourself emptying your cup every few hours, you might want to size up for your heaviest days, making that “I need to change” anxiety a thing of the past.
