Northwind Unders

When the temperature gets to the teens or lower, these are my go to underwear option. I have never felt the cold with them on and they are always comfortable.

Awesome undergarment!

I run in all types of weather, and these wind block boxers absolutely allow me to do that, even on very cold, windy Maine mornings. I HIGHLY recommend them, as I have several pairs.
