It's A Swamp Out There: 14 Cotton Undies To Keep Your Vagina Feeling Fresh

Welcome to Hype Machine, our hit-list of the top reviewed products across the web — according to a crowd of die-hard shoppers. Call this your 4-star & up only club, with entry granted by our devoted-to-the-goods shop editors.
Gal pals: we’re on the brink of summer — a season that brings warm weather, vacations, and regrettably, an increase in down-there issues. Higher temperatures mean more sweat and the heightened possibility of nether-region irritation, and we’re already on the hunt for undergarments that will do the least harm in during this extra-risky time.
Truth is, even though silk sounds and feels luxurious, the better fabric for your vagina when the temperatures climb is cotton. “Cotton in general tends to be non-irritating to your skin,” says Raquel Dardik, MD, of the Tisch Women’s Health Center. “The external skin around your vagina is like regular skin, but just a little bit more sensitive. So if you have material that irritates your skin normally, you might have minor inflammation to the area.”
It's not just a skin issue, though. Cotton is known to be one of the most breathable types of fabrics out there, which makes it better for your skin — and also your vagina. “Most of the synthetic fabrics, as well as silk, are not that breathable,” Dr. Dardik says, “and for women who have sensitive skin and yeast infections, the most breathable material is really what works best.”
Why? Well, yeast thrives on moisture — so if you trap moisture in your fussy silk underwear, you're creating a prime breeding ground for an infection (ouch). “Of course, if you're the kind of person who never has issues with vaginal irritation and infections, you can wear whatever you want,” Dr. Dardik says. But if you're prone to annoying vaginal problems, opting for cotton underwear — or at the very least with cotton lining — is your best bet.
Still, we wouldn't want to deprive you of buying cute lingerie, chill boy shorts, even the thongiest thongs that your underwear drawer needs. So for this edition of Hype Machine, we combed all of the reviews and rounded up the highest-rated cotton underthings for you, your wardrobe, and of course, your vagina.
At Refinery29, we’re here to help you navigate this overwhelming world of stuff. All of our market picks are independently selected and curated by the editorial team. If you buy something we link to on our site, Refinery29 may earn commission.

The Hype: 4.8 out of 5 stars; 90 reviews on

Elacucos Cotton Thong (6-Pack)

Best Economy Thong Buy

If you’re looking to economize your cotton thong purchase, look no further. This multipack contains cheek-baring undies that satisfy many thong-wearers’ requirements without breaking the $10 threshold.

The Hype: 4.4 out of 5 stars, 1,812 reviews on

What They Are Saying: “After purchasing this 6-pack they became the only underwear I wore, when I put on others the comfort does not compare. You get the comfort of cotton undies without having to wear the “granny panties” commonly associated with cotton. They are a good quality, not too thin, and have held up through many washes (important for underwear) without any change to size.”

What They Are Saying: “I’ve been wearing these briefs for several years and would not wear anything else. What makes these the best: the soft cotton, seam in back makes for a better fit, the elastic which isn’t too heavy or thick, and last but not least, no ride up.” — Lana, reviewer

Natori Bliss Girl Cotton Brief

The Prettiest

If you’re a frills-and-lace kinda gal, you may find that cotton underwear often comes up short (ha!) in this department. However, leave it to Natori to dress up the simplest of styles — reviewers declared their breathable brief to be the prettiest cotton underpants they’d encountered.

The Hype: 4.6 out of 5 stars; 38 reviews on

What They Are Saying: “I really think these are the most comfortable panties that are actually pretty as well. This is the only style I buy — they fit well and do not lose their shape, and are simple yet still kinda sexy.”

The Hype: 4.5 out of 5 stars; 98 reviews on

Hanky Panky Organic Cotton Boyshort

Best Eco-Forward

If you’re looking for an eco-forward pair o’ panties, these organic cotton boyshorts might be your best bet. Reviewers praised their comfort, great fit, and environmentally-friendly composition.

The Hype: 4.8 out of 5 stars; 20 reviews on

What They Are Saying: “These are perfect for the days you just really want a cotton pair of undies. The lace helps disguise the lines but you still get all the comfort of the cotton. Organic undies are pretty hard to find so I was excited to see these. I have purchased so many cheaper pairs that just end up having at least one characteristic that bugs me. Not these — they are perfect.”

Cacique Cotton Ruched-Back Cheeky Panty

Best Cheeky Pair

The recent rise — get it? — of the “cheeky” underpant has been welcomed by those of us who want less-than-total coverage, but have yet to board the train to Thongtown, USA. Plus-size customers are very satisfied with this seamed, cheek-baring style.

The Hype: 5 out of 5 stars; 14 reviews on

What They Are Saying: “They fit great if you like less backside coverage. I can't wear most full coverage styles because they have too much fabric in the back and tend to bunch or ride up. These are the perfect middle ground between a thong and a hipster or brief.” — Emily83, reviewer
