Introduction to Saalt vs Hello Cup Overview

When it comes to reusable menstrual cups, the quest for the right fit, softness, and leak protection can feel overwhelming. Two of the most talked-about options are Saalt and Hello Cup—both offering high-quality materials made with custom designs but with unique features that set them apart.

Choosing between the Saalt and Hello Cup often starts with understanding your own body and preferences. Are you looking for a cup that's exceptionally soft and gentle, ideal for postpartum recovery or sensitive anatomies? Or is your priority a firmer, more secure fit that supports an active lifestyle and resists leaks during long days out or while sleeping?

From design differences to sizing options, each cup takes a slightly different approach to comfort and usability. Some users prioritize the ease of removal and cleaning, while others care most about the range of sizes and styles available to accommodate bodies at every life stage—from first periods and pregnancy through to menopause.

The Saalt and Hello Cup both promise reliable leak protection and aim to take the stress and unpredictability out of period care. But details like firmness, cup capacity, cervix height, and how easy it is to form a secure seal can make a big difference in your day-to-day experience. Let's take a closer look at how these two options stack up.

Material Composition and Safety Certifications

When considering the best reusable menstrual cup for your needs, the material it’s made from and the safety standards it meets become critically important. Both the Saalt and Hello Cup are designed with user health in mind, but they take slightly different approaches when it comes to composition and certifications.

Most high-quality menstrual cups, like Saalt Cups, are made from medical-grade silicone—a material favored for its flexibility, hypoallergenic properties, and durability. Medical-grade silicone is non-porous, which means it’s resistant to bacterial growth and can be easily sanitized between cycles. Some cups, like the Hello Cup, opt instead for thermoplastic elastomer (TPE). TPE also boasts hypoallergenic benefits, is sometimes softer to the touch, and retains its shape well after repeated use.

Safety certifications are an extra layer of reassurance. Look for cups that are FDA-registered and adhere to ISO standards for medical devices. These certifications are not just regulatory checkboxes but real indicators of manufacturing quality and safe contact with sensitive tissues. Products that undergo independent lab testing for toxins, dyes, and allergens give additional peace of mind that what you’re putting in your body is thoroughly vetted and safe for repeated, long-term use.

The bottom line? Whether you lean toward medical-grade silicone or TPE, choosing a cup that prioritizes both quality materials and rigorous safety certifications sets you up for a worry-free and comfortable experience, cycle after cycle.

Softness and Firmness Side-by-Side

When shopping for a period cup, the way it feels—softness versus firmness—can make or break your experience. These qualities impact comfort, ease of insertion, and even leak protection. So, let’s roll up our sleeves and break down what you really get with a Saalt Cup compared to a Hello Cup.

The Hello Cup is known for striking a balance between firmness and flexibility. It tends to be on the firmer end of the spectrum before insertion. However, after insertion, the material, once warmed to the body, quickly softens, which can make it challenging to pop open and place for those with a strong pelvic floor. However, the softness of the TPE makes it ideal for those with a sensitive bladder or low cervix.

By contrast, the Saalt Cup comes in two firmness levels: the original Saalt Cup and the Saalt Soft Cup. That softer silicone really pays off for people seeking a “barely-there” feel. It molds gently to your body, which is ideal if you've found firmer cups uncomfortable in the past or if you experience bladder sensitivity. The trade-off is that softer cups may require a touch more finesse during insertion to ensure they open fully.

In practical terms, it boils down to your priorities and anatomy. If you need a cup that opens reliably and isn't easily dented by your pelvic muscles, a firmer option like the original Saalt Cup would fit the bill. If comfort, flexibility, and gentle pressure are non-negotiables, then a softer cup like the Hello Cup or Saalt Soft may feel like a dream come true.

No matter which direction you lean, softness and firmness are all about creating the best fit for your body and your lifestyle.

Size Range 

Finding the right fit is key to period protection that feels comfortable and actually works. Reusable menstrual cups and discs come in different sizes and shapes, but it’s not just about “small, medium, and large.” It’s about capacity (how much it holds), diameter and length (how it fits your body), and firmness (how it feels once it’s in). Below, see how sizing and capacity compare between these two leading brands:

How to Choose the Right Size

• Consider your flow: Heavier flows usually need a cup with higher capacity.

• Think about comfort: If you’re sensitive or new to cups, starting with a smaller or softer version can help.

• Body changes matter: If you’ve given birth vaginally, have a higher cervix, or are in postpartum recovery, the larger or longer options can be a better pick. Understanding your cervix height is crucial for perfect cup sizing. For a lower cervix choose a low cervix or small cup, and for a higher cervix choose a high cervix or large/regular cup. Learn: How to measure your cervix height. 

• Don’t forget activities: If you’re active or on the go, a sturdier, snug fit may give you greater confidence and leak protection.

Hello Cup comes in a wide array of sizes and styles, but only a single firmness level for all. They have low cervix cups, available in medium and large, the standard Hellp Cup for average cervix heights in small, medium, and large, and a high cervix cup available in small, medium, and large. Their array of sizes means you’ll find the perfect size for you. Alternatively, the Saalt Cup comes in three sizes: The Saalt Teen Cup, the Saalt Small Cup, and the Saalt Regular Cup. The Saalt Small and Regular cups come in a soft cup version for those sensitive to firmer cups, bladder pressure, or frequent cramping. Both brands offer an array of sizing options, and with Saalt’s soft cup options, finding the perfect cup can be realized. 

How Design Impacts Fit and Seal

When it comes to menstrual cups, design isn't just about aesthetics—it’s the difference between all-day confidence and constant worry. The shape, rim thickness, and grip features all play a huge role in how a cup fits your body and maintains a leak-proof seal.

Most cups are shaped like a bell or a V, but don’t let that simple silhouette fool you. Small design tweaks—like a pronounced rim or extra flexibility in the base—can have a big impact on comfort and how securely the cup stays in place. A cup that’s too rigid might feel uncomfortable, while one that’s too soft may not fully open inside, leading to leaks. The Hello Cup has a V-shape design while the Saalt Cup is a more bell-shaped silhouette. Traditionally, the V-shape of some menstrual cups are held in place by its rim, while the bell-shape of other menstrual cups are held in place by both the rim and the bulb of the cup. The rim of the Hello Cup is both firm, to retain shape during insertion and placement, but also has minimal outward curvature on the outside with no rim curvature to reduce pressure. The rim of the Saalt Cup, while curved outward to help seal, it is soft and pliable. Because the Saalt Cup is held in place by both the rim and bulb, the rim of the Saalt Cup isn’t overly firm to singularly hold the cup in place. 

Another crucial factor is the air holes near the rim. These tiny details help create suction, which is what keeps the cup sealed against the vaginal walls. Without a reliable seal, leaks can happen even when the cup is technically “in place.” Look for a design that balances flexibility with enough firmness to pop open and lock in effortlessly, especially if you have a higher or lower cervix, or a weaker pelvic floor. The difference between TPE and medical-grade silicone might be a factor for finding the right material for your anatomy. There can be trial and error in finding the right cup for your body, and that’s okay. 

Grip rings and stems seem minor, but they’re lifesavers when it comes time to remove the cup. Smart design here prevents slip-ups and makes it easy to adjust or empty the cup without discomfort. Materials matter too—the Hello Cup has more of a matte finish that helps secure the seal, while the Saalt Cup has a smoother, silkier finish. Both the Hello Cup and Saalt Cup have grip rings and stems to aid with removal. However, the Saalt Cup grip rings are a little more pronounced, which is helpful for grip during removal, and the Saalt Cup stem can be cut to desired length. The Hello Cup stem cannot be altered without damaging the cup. 

Ultimately, it’s these thoughtful design elements that set one cup apart from another, tailoring the fit and seal to your unique needs. The right design means more freedom, fewer interruptions, and peace of mind, no matter what your day throws at you.

The Bottom Line: Saalt vs Hello Cup—Which One Is Right for You?

Choosing between Saalt and Hello Cup boils down to your priorities: comfort, fit, sustainability, and how much leak protection you really need. If you’re seeking a cup with ultra-soft, flexible silicone that feels like it was made just for you, Saalt’s premium cup line shines—especially for those with sensitive anatomies or anyone navigating postpartum recovery or bladder leaks. Our cups were designed with this comfort and adaptability in mind, so you can confidently go about your day, whether you’re parenting on the go, getting active, or simply taking care of yourself. 

Hello Cup, meanwhile, brings a firmer feel and quirky colors, which some users love for sports or a snug fit. Their ultra-low-profile, low cervix cup is hailed by many as being the perfect cup for low cervix folks. But if leak protection is your top concern—and you’re looking to ditch single-use products or the embarrassment of bathroom “emergencies”—Saalt’s combination of advanced design, medical-grade materials, B-Corp sustainability creds, and ongoing charitable impact ticks every box.

Ultimately, the better cup is the one that gives you freedom from leaks and peace of mind, wherever life takes you. And if you’re looking to cover all your bases, Saalt leakproof underwear partners perfectly with our cups for stress-free, sustainable protection every single day.

Frequently Asked Questions: Saalt vs Hello Cup

What are the main differences between Saalt and Hello Cup in terms of softness?

When comparing Saalt and Hello Cup, softness is a standout feature. Saalt cups are well-known for their velvety soft silicone and two firmness levels, making them a great option if you prefer a gentle, flexible fit. Hello Cup uses a medical-grade thermoplastic elastomer (TPE), which is slightly firmer before insertion and offers a springier feel. Once the Hello Cup is inserted, it quickly softens as it warms to your body, but many people report challenges in cup placement after insertion as the cup can become too pliable. The difference in material means Saalt cups can feel softer to the touch and more comfortable, and maybe reliable for extended use, especially if you're sensitive or new to menstrual cups.

Which menstrual cup is softer, Saalt or Hello Cup?

Saalt cups take the win here. Their silicone is designed for plush comfort, molding gently against your body, whereas Hello Cup’s firmer TPE offers more resistance. If you’re seeking the softest possible cup for sensitive bodies or postpartum changes, Saalt’s flexibility is tough to beat.

How does the fit of Saalt compare to Hello Cup?

Both Saalt and Hello Cup come in various sizes, but the fit experience is different. Saalt cups have a rounded, tapered shape and soft, flexible grip for ease of insertion and removal. Hello Cup’s V-shaped design sits a little higher and may suit those who want a slightly firmer cup rim that pops open easily. If you have a low cervix or are in postpartum, Saalt’s flexibility and range of sizes in both cups and menstrual discs make it a friendly fit—offering comfort during both movement and rest.

Is one cup more comfortable than the other?

Comfort is personal, but many users find Saalt cups more comfortable due to their ultra-soft silicone, which adapts to your movements throughout the day. Hello Cup’s firmer TPE can be preferred by people who want a cup with more “bounce-back” or a firmer feel. Note: users report that the Hello Cup quickly softens after insertion, making it challenging to find the right positioning and placement. For the majority—especially those new to cups or experiencing leaks during exercise, postpartum, or with a sensitive bladder—Saalt stands out for all-day, barely-there comfort.

Which cup is better for beginners, Saalt or Hello Cup?

Though both are well-regarded, Saalt’s gentle flexibility and soft edges make it an easier choice for first-timers. The softness means it’s simpler to fold and insert, and the grip on the base of the cup ensures easier removal. Add in their straightforward sizing and silky finish, and Saalt becomes a trustworthy pick for anyone starting their reusable journey—whether you’re managing periods, postpartum flow, or even bladder leaks.
