5 Insanely Comfortable Cotton Briefs for Women

If your underwear leaves red marks, bunches in weird places, or makes you question your life choices by 3 p.m., it might be time for an upgrade. Supima® cotton briefs are here to end the cycle of settling—for fabric, fit, and overall comfort.

In this guide, we’re spotlighting five styles from SPANX made with ridiculously soft Supima cotton. From barely-there smoothness to breathable shapewear that doesn’t squeeze the life out of you, each pair is engineered for comfort that lasts way past laundry day. 

But first, let’s break down why Supima cotton briefs are the ones worth swiping right on.

4 Benefits of Supima Cotton Briefs for Women

Let’s take a moment for all the briefs of the past—the ones that pinched, rode up, and got weirdly see-through after a couple of washes. Supima® cotton briefs are here to raise the bar (and your standards). Here's why they’re better than whatever’s in your underwear drawer right now:

1. Stronger Than Standard Cotton

Supima® cotton is made with extra-long staple fibers, which makes it up to 45% stronger than regular cotton. That means no saggy waistbands, no thinning fabric, and no post-laundry disappointment. These briefs hold their shape, wash after wash.

2. Lightweight and Breathable

If your current pair feels like you’re wearing a wool sweater in July, it’s time to let them go. Supima cotton is naturally breathable and moisture-wicking, keeping things cool and fresh—no matter what’s going on under your outfit.

3. Seriously Soft

You know that pair you always dig out of the drawer first? Now imagine every pair feels like that. Supima cotton’s finer fibers give it a luxuriously soft finish—smooth enough to feel like a second skin, and then some.

4. 4-Way Stretch That Moves with You

You deserve underwear that keeps up. SPANX’s Supima cotton briefs offer 4-way stretch for unrestricted movement. Walk, sit, stretch, or sprawl across the couch—your briefs won’t budge, dig, or remind you they exist.
