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!

I’m an elementary PE teacher and MOVE ALL DAY. These are the only undies that keep up and are so comfortable! Love them.

Love these undies

I ordered a few years ago my first pair of Thunderpants and I will always have these pants in my life. Zero wedgies, so much comfort. Love my undies, love my bikini. Thanks for doing what you do.

Love Letter To Underwear and the Creators

If I were to go back 7 years and tell myself that I would be writing this love letter to the perfect underwear, I don’t think that my past self would believe it. Thunderpants, I have been looking for you ever since I can remember. Over the years I tried over 10 different brands of the “most comfortable underwear” only to be disappointed when they all gave me wedgies. To find you, brings me more joy than I can even express! Because of you I am able to get through the day comfortably without needing to yank at my bum to get you out of my crack. With you in my life I am able to be present, flexible, and sexy! Each month I am getting rid of the underwear from the past to make room for a new pair of the love of my life. You will forever have my bum and heart. With love, One of your biggest fans
