Original Plain Vanilla

$ 26.00
Select my color — Plain Vanilla

Made in USA

Organic Cotton


The perfect pair of undies to wear under your light colored clothing. Vanilla is un-dyed natural cotton, not a bleach white.

Fit models (in Vanilla):

Breana is wearing a size 2XL Original: 5'4" tall, 46” bust, 37” waist, 53” hips

Caitlin is wearing a size MED Original: 5'5" tall, 34" bust, 30" waist, 40" hips

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!

Recommend these heartily, no notes.

I was constantly jealous of the undies I was buying for my five and seven year old daughters, and kept writing reviews asking that retailer to make adult sizes. They were so great - soft organic cotton, thick enough to keep their shape wash after wash, a high waist, and back coverage that goes all the way under the cheek. This was the first place I’ve found that unicorn of an underpant in a grownup size. That plus the variety of cute designs and colors - I’ll never go back to buying undies from the gap out of desperation. I have enthusiastically recommended these to friends, whether they asked or not. I’m around a size eight or ten for most pants and I like the fit of a size L in these. If you love comfort, try these out.
