4 Reasons Supima Cotton Thongs Belong In Your Underwear Drawer (Plus 4 Styles)

written by  Kylah Field

A lot of thongs were clearly designed by people who’ve never had to wear one for more than ten minutes. Too tight, too scratchy, and weirdly invasive? Been there. But it doesn’t have to be that way, because SPANX is finally giving thongs the upgrade they (and you) deserve. 

Supima cotton thongs are here to do the unthinkable: feel good, breathe easy, and stay exactly where they’re supposed to.

SPANX Supima cotton thongs take everything you hate about your old underwear drawer and throw it in the wash—on a gentle cycle, of course. Known for their buttery-soft fabric, seamless design, and innovative shaping tech, these thongs are the definition of “how did I live without this?” 

By the time you finish reading this, you just might feel inspired to swap every single pair of underwear you own. And honestly? You should.

4 Benefits of Supima Cotton Thongs

Let’s pour one out for the thongs of yesteryear—the ones that dug, bunched, and ghosted your comfort the moment you left the house. Supima® cotton thongs are here to clean up the mess with four undeniable perks that your current underwear drawer can’t compete with.

1. Stronger than Standard Cotton

Supima® cotton isn’t your average cotton. With extra-long staple fibers, it’s up to 45% stronger than standard cotton. Translation: Your thong won’t turn into a string after a few washes. You get lasting shape, fewer holes, and fabric that keeps its cool no matter how many times it hits the laundry.

2. Lightweight and Breathable

If your current underwear feels like a personal sauna, it’s time for a change. Supima cotton is naturally breathable and moisture-wicking, which means it helps regulate temperature and keeps things feeling fresh. 

3. Super Soft

You know that one pair of underwear you reach for every time laundry day rolls around? Multiply that by four. Supima cotton’s finer fibers make it softer than regular cotton—so it glides on like a second skin and never overstays its welcome.

4. 4-Way Stretch

Comfort that moves with you—not against you. SPANX’s Supima cotton thongs feature 4-way stretch that flexes in every direction, so you’re free to sit, walk, bend, and power-strut through your day without a single adjustment.

The 4 Best Cotton Thongs for Women

If you’ve made it this far, you’re probably ready to commit to the cotton thong lifestyle. Good news: SPANX has four styles that bring Supima’s signature softness and stretch to a new level—with shaping, smoothing, and stay-put features that finally deliver on the promise of all-day comfort.

SPANXshape Invisible Supima Cotton Thong

This thong is where shaping meets barely-there brilliance. Our SPANXshape™ Invisible Supima® Cotton Thong blends powerful tummy control with ultra-light compression, all wrapped in premium Supima cotton. Thanks to the Printed Power® shaping tech (yes, it’s as high-tech as it sounds), you get 360-degree smoothing that actually stays in place. No rolling, no pinching—just seamless shaping that disappears under everything.

The real magic lies in LYCRA® FitSense™ Print Technology. This first-to-market innovation bonds shaping power directly to the fabric, meaning no added bulk or seams to ruin your look. With a silicone waistband that holds its ground, moisture-wicking properties to keep you cool, and a cotton gusset for bonus comfort, this thong feels like nothing and does everything.

SPANXshape ExtraOrdinary Supima Cotton Thong

Mid-rise, high praise. Our SPANXshape™ ExtraOrdinary Supima® Cotton Thong delivers medium coverage in the front, a classic thong back, and a whole lot of comfort in between. This style features a dig-free waistband with just the right amount of compression for subtle shaping, while still letting your body do its thing.

Made with soft, breathable Supima cotton and 4-way stretch, this thong moves with you from brunch to boardroom without breaking a sweat. It’s smooth, seamless, and anything but basic—perfect for the days when you want coverage, control, and zero visible lines.

SPANXsupersmooth Undie-tectable Supima Cotton Thong

You know that feeling when your underwear disappears under clothes like it’s not even there? That’s the Supersmooth Undie-tectable Supima® Cotton Thong doing its thing. Bonded edges mean no visible panty lines, no digging, and no “what’s that line under your dress?” moments. It’s just smooth, clean coverage with a little extra shaping magic built in.

The mid-rise fit features a bonded waistband for gentle tummy smoothing, a cotton gusset for all-day wearability, and breathable Supima cotton that moves with your body—not against it. Elastic-free edges give this thong its name: Undie-tectable®, in every sense of the word.

SPANXsmooth Fit-To-You Supima Cotton Thong

Let’s hear it for a thong that adapts to your body, not the other way around. Our Fit-To-You Supima® Cotton Thong is crafted with 400% stretch fabric that molds to your shape and retains it wear after wear. The result? A second-skin fit that feels custom-made.

Available in a 3-pack (because one is never enough), this thong also features bonded seams and elastic-free edges that make panty lines a thing of the past. It’s soft, breathable, and smooth enough to disappear under leggings, dresses, or anything clingy. If your current underwear is still trying to figure out how to behave under a bodycon dress—consider this your upgrade.

How to Care for Supima Cotton Thongs

Want to keep your new favorites in rotation for the long haul? Here’s how to treat them right.
