Choosing the right absorbency in leakproof underwear can feel like a guessing game, especially with so many options on the market. But getting it right is the key to staying comfortable, confident, and leak-free all day long. Whether you're new to period panties or looking to refine your collection, understanding absorbency levels is essential.
In this guide, we'll break down the different absorbency levels, help you match them to your flow, and share tips for building a versatile period underwear drawer. By the end, you'll know exactly which styles to reach for on heavy mornings, light afternoons, and everything in between.
What Do Absorbency Levels Mean?
Leakproof underwear absorbency refers to how much fluid the gusset (the protective layer in the crotch) can hold. Most brands, including Saalt, categorize their period panties into light, moderate, and heavy absorbency levels. These levels are typically measured in milliliters (ml) or equivalent tampon counts, making it easier to compare with your usual period products.
Light absorbency (about 1-2 tampons or 5-10 ml) is ideal for spotting, discharge, or the last days of your period. Moderate absorbency (about 2-3 tampons or 10-15 ml) suits average flow days, while heavy absorbency (4+ tampons or 20-30 ml) is designed for overnight protection or heavy flow days. Understanding these ranges helps you choose the right pair for each moment.
- Light: spotting, discharge, or end-of-period
- Moderate: average flow days
- Heavy: overnight or heavy flow days
How to Match Absorbency to Your Flow
Your menstrual flow isn't the same every day, so your leakproof underwear shouldn't be either. Start by tracking your flow for a couple of cycles. Note which days are heaviest, which are lightest, and whether you experience spotting between periods. This will help you identify your personal absorbency needs.
On heavy days, you'll want maximum protection. Look for high-waist styles or those marketed as 'overnight' or 'heavy flow.' For lighter days, a sleek brief or hipster in light absorbency offers comfort without unnecessary bulk. Many people find that a mix of absorbencies works best—like using heavy for nights and moderate for busy workdays.
Saalt's Absorbency Options
Saalt offers a range of leakproof underwear designed to cover all flow levels. For light days, the Leakproof Teen Brief is a great choice for younger bodies or those who prefer a lower rise. For moderate to heavy days, the hanky panky+ [powered by Saalt] French Brief and hanky panky+ [powered by Saalt] V-kini provide both style and function, with absorbent gussets that keep you dry.
If you're looking for a versatile set, the School's In Session 5 Pack includes multiple pairs with different absorbencies, perfect for building a starter wardrobe. And for those who want extra coverage overnight, consider pairing your heavy-absorbency underwear with a Saalt Disc for double protection. The Saalt Disc is a reusable menstrual disc that can hold up to 30-40 ml, making it an excellent backup on your heaviest nights.
Tips for Building a Leakproof Underwear Wardrobe
To get the most out of your period underwear, aim to have enough pairs to cover your entire cycle. A good rule of thumb is to have at least 3-5 pairs, mixing absorbency levels. For example, you might have two heavy pairs for nights, two moderate pairs for workdays, and one light pair for the final days.
Don't forget to consider your lifestyle. If you're an athlete or tend to sweat, look for moisture-wicking fabrics. If you're postpartum, you may need higher absorbency and more coverage. Saalt's postpartum underwear line offers extra support and leak protection, making them a comfortable choice during recovery.
