Comfy underwear are real! The secret is just that they're designed by women 😮‍💨

Here at Thunderpants, we believe that everyone deserves a comfy bum, and we feel lucky to know just how to help you find that 🍑 Our underwear are made of a fabric blend that is custom-milled in Los Angeles with 90% organic cotton and 10% spandex, giving you not only support but comfort. That same fabric is used to self-bind our underwear and fit to your thighs and waist, feeling like a hug for your body!

Available in several different styles and in inclusive sizing, we're proud of the product we share and the comfy bun club who wears them ⚡️

After all, wedgie-free underwear designed by women and made here in the United States with organic cotton? That's our mojo.

Look no further than these! 🎀 These Organic Cotton Scrap Scrunchies are another way we make use of scrap fabric instead of sending it off to a landfill.
