The year is 2021, and we expect big things from the feminine hygiene products industry. Many of us have already made the switch to period panties, and now we have our sights set on leak-proof apparel, particularly in the fitness department. Say hello to period-proof workout leggings: all-star athletic pants you can rock with peace of mind, no matter the time of the month.
Period-proof workout leggings are similar to period underwear in that they have built-in liners that soak up blood. But with leggings, the idea is that you can go underwear-free with a tampon or menstrual cup and not worry about it leaking through. "There are many so styles that you can find one that's comfortable and best suited for your activity," says board-certified OB/GYN Dr. Carolyn Moyers. Additionally, according to Dr. Sherry Ross, an OB/GYN and women's health expert based in Santa Monica, some pairs can be worn without a tampon or cup, while others are designed to hold a pad securely in place.
Scroll down for the best period-proof workout leggings currently on the market.

Who else recommends it? Cosmopolitan also picked the Thinx Period Active Leggings.
What do buyers say? 50+ Thinx reviewers rated this product 4.6 stars or above.
From the brand that started it all, Thinx makes the best workout pants for menstruation. Period Active Leggings are great for jogging, hiking, taking a barre class, practicing yoga, or sweating up a storm during a HIIT (high-intensity interval training) routine.
Featuring a built-in liner that can absorb as much as three tampons-worth of blood, they're suitable for vigorous workouts or all-day athleisure wear on moderate-flow days. The soft, stretchy material and high waistband keep you comfy while preventing leaks. They also pass the squat test with flying colors and offer plenty of breathability where you need it most.

"Cotton leggings may be best for overall comfort," says Dr. Sherry. That's why we're loving this budget-friendly pair from Ruby Love, which is made of 90 percent cotton and 10 percent spandex for a perfectly breathable, stretchy fit. Designed to work just like the brand's period underwear, the Period Legging features a dual-layer leak-proof liner made of absorbent cotton and dri-tech mesh.
If you like high-waisted compression to combat bloat, these pants might not be ideal, as they sit just below the waist. However, they offer a comfy, leak-free fit for running, strength training, yoga, pilates, and nearly any other activity.

"On light days, period underwear can be used alone," says Dr. Moyers. With that said, your best bet for working out is the Leakproof High Rise Thong from Knix. Thanks to an ultra-absorbent liner with the brand's Fresh Fix Technology, the waterproof design absorbs blood and prevents leaks.
This fitness-ready thong can hold up to a teaspoon of blood or sweat, and the anti-odor gusset will keep you fresh while you move. What's more, the seamless cut is virtually invisible underneath the workout leggings of your choice.
Material: Nylon, lycra, cotton, spandex, polyester | Size Range: XS–4XL | Absorbency: Light | Colors: Black, pink, beige
Final Verdict
The best period-proof workout leggings overall are Thinx Period Active Leggings on account of the soft, stretchy design and built-in liner that can hold up to three tampons worth of blood—extra points for the inclusive size range. Having said that, if you want something with a little more absorbency or prefer a 7/8 cut, you can't go wrong with Adidas Techfit Period-Proof 7/8 Tights, which offer three layers of Flow Shield protection.

What to Look For in Period-Proof Workout Leggings
Liner
The most critical feature of period-proof workout leggings is the built-in liner. Like period underwear, the absorbent layers soak up blood and wick away moisture for leak-resistant protection while you move.
You'll find options with double- or triple-layer linings that can hold anywhere from one to five tampons-worth of blood. Absorbency is crucial, but breathability is also important, as you want something that'll keep you dry and odor-free.
Material
According to Dr. Sherry, cotton will provide the most comfort, as the material is naturally breathable and moisture-wicking. But as mentioned above, breathability matters most in the liner.
For the rest of the pants, you'll want the fabric to be stretchy, soft, and supportive enough to pass the squat test. Look for styles made from synthetic materials like nylon, lycra, spandex, elastane, and polyester.
Color
Dr. Sherry suggests getting period leggings in a dark hue, as it will conceal not only potential leaks but also sweat when you're working out. Most styles come in black, though you'll find other deep colors, like olive green, charcoal, and navy, as well as some printed designs.
