The people who know about these things told us we need longer product descriptions to satisfy google (our overlord of online searches). Did you know A.I. can write production descriptions now?? All we have to do is give it some appropriate key words and boom! So easy! Look at this masterpiece. We really can't stop laughing.


"Original Autumn Equinox offers organic cotton underwear that is comfortable and wearable all day. Powered by oranges from the sun and moon, these undies provide you with an unprecedented level of support so you don't have to worry about wedgies."


Here are the keywords we provided: organic cotton, underwear, oranges, sun, moon, no wedgies, comfortable, wearable.


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!
