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.


Oksana is wearing a size MED Original

Fit models (in Plain 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!

A lot of coverage

I am used to wearing Hipsters, but this style does stay in place well. I am 5’7” & 133 lbs., size 8-10, with a short waist/long legs. Thunder pants Hipster slide down in the back on me. I tried a medium, but settled on. Large for both the Hipster & the Original panties.

Lucky Undies

I was lucky to find original vanilla was in stock, but the only thing plain about this comfy supportive pair of underpants is the plain old good product! The fun prints offered are a bonus, but this covers all bases and I can wear these under white pants!!!

Beyond comfort and my style

Everything about these are awesome. I own nearly ever colorway but my favorites are the hand dyed or tie dyed.
