Original Under the Sea

$ 24.00

Made in USA

Organic Cotton


Dive into our new underwater adventure print by whimsical illustrator Abbie Ren.

The Original comfy undies that don't go up your bum. In sizes small - 3x large 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 their 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!

Love one, not the other.

I brought 2 medium undies. One fits, the other one is too small. I based my purchase on a pair I bought in a store. Other than this, I love these prints, and the one that fits is super comfortable. Thanks

Love, love this green clover dye. It was sold out and when I contacted customer service to see if they would be making any more I was happy to hear they were in the process and I put my order in immediately. I love the clover color as well as all of my other thunderpants they are so comfortable. A shout out the their customer service department as well, they have been so helpful whenever I have had a question. Love this company and its values. If you on the fence jump over you won’t be sorry!!
