The Best Anti-Chafing Underwear: Say Goodbye to Thigh Rub
If you’ve ever walked a block (or danced a wedding) in the wrong pair of underwear, you know the sting of chafing. It starts as an annoying rub and ends in a full-blown countdown until you can get home and change. Spoiler: It doesn’t have to be this way.
Chafing happens when moisture, heat, and friction get together—usually in fabrics that trap sweat, don’t breathe, or cling in all the wrong places. Lacey details might look good on the hanger, but they’re often a fast track to irritation. Thankfully, womens underwear can be soft and smooth without turning into a personal heat trap.
The right pair makes a difference, and we’ve got the proof. From thongs to briefs to bikinis and tangas, here’s everything you need to know about choosing anti-chafing underwear that keeps things breathable and comfortable under any outfit.
Anti-Chafing Thongs
Thongs might seem like the last thing you’d reach for when you’re trying to avoid irritation, but that’s only true if they’re made from stiff, sweaty materials. The right thong fits like it’s barely there and stays smooth no matter how much you move.
