Boxer Brief Blueberry Blue

$ 34.00
Select my color — Blueberry Blue

Our new and improved Boxer Brief!

This new design is based on what was previously called our "Men's Boxer Brief". The old style had a double layer of fabric in the front pouch. We have taken it down to a single layer and flattened it out making it suitable for all genders. 

Our signature fabric has plenty of stretch to be very accommodating or lay flat across the body. We also adjusted the rise a bit so they sit a little higher. The legs are the same length, more of a short trunk style, hitting the upper thigh.

The Boxer Brief has a single layer front flat gusset. Our signature fabric has plenty of stretch to be very accommodating or lay flat across the body, making it suitable for all genders. The legs a short trunk style, hitting the upper thigh.

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!

These are cute, high quality, well made, and terrific value. The price doesn't seem high enough once you get them on. Finally, some underwear in great cuts made of GOOD fabric again!

My favorites!

You know how you have a drawer of underwear but there are only a few pairs you always reach for? Those are my Thunderpants. I need to get rid of all the other kinds I have because it just isn't fair to them. I only want to wear my Thunderpants.
