The Original comfy undies that don't go up your bum. In sizes SM - 4XL this very comfortable full brief sits in the natural crease at the top of the leg and usually hits just below the belly button. The Original is a higher rise, but not a high waisted undie. This is our most popular style and easily fits many body types.
Thunderpants 90% organic cotton/10% spandex fabric is sturdy, very stretchy, and has great retention to give our garments just enough stretch and bounce back. It helps the undies to stay up and on, and the other garments to keep their shape without sagging or bagging. We use the same soft organic cotton blend to cut our binding into a wide strip instead of using elastic so there is never any irritating elastic against your skin. All the garments are made locally and lovingly in Portland, OR.
To preserve the vibrant colors and life of the fabric we suggest you do not soak or bleach your Thunderpants items. Use a gentle detergent in a cold machine wash and dry your Thunderpants on the line (they will survive drying on low, but may fade a bit and cut down slightly on longevity). If you do wash warm or dry, make sure not to use too much heat as heat will break down the spandex!
All our prints are designed by artists and are limited edition. They don’t stick around long, but there is always something cute on the way!

I love Thunderpants!
Always comfortable, a women-owned business in Portland. What’s not to love?

I love these
They are so soft and comfy and cover everything and the color is gorgeous

A comfort classic!
I have been wearing original thunderpants for years. I love the high quality fabric and the comfort is outstanding. They last forever too if you air dry them. I wouldn't wear any other brand as I feel I found the best.

Like a warm hug for your dainty bits
Consistently good quality. Wash beautifully. I even throw them in the dryer with no problem. Hey meow! has become my favorite print.

The best underwear
I LOVE Thunderpants and am slowly replacing all of my underwear with these. Well-made, beyond comfortable, super cute patterns, responsible company, size inclusive--y'all are the best.
