Our limited edition Emerald Thundies are hand-dyed using a dip technique. This technique creates a marble effect. Each one is made to order and will have some variation in color and coverage. There is only a limited amount available.

We are doing an entire Hand Dyed Collection this year. We've selected eight colors that we think you're going to love! You can collect each color as they are released throughout the year. Keep an eye out for the next color coming soon.

No exchanges or returns on limited edition pairs. Please message us with any questions about fit if this is your first pair of Thunderpants!

The Original comfy undies that don't go up your bum. In sizes small through to 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.

Make sure to wash these alone or with like-colors for the first few washes (don't wash them with whites right away!). The dyeing process does leave a faint scent, this is not scented detergent, we only use un-scented when washing before and after dyeing. The smell of the dyeing process will fade over time.

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!
