Flame Retardent Kevlar Boxer Shorts

This defeats the whole purpose of going commando, and might muffle the sound of my balls going CLANK!
I had a pair of Massif nomex boxers I would wear on vehicle patrols. They didn't stop any bullets or anything but they didn't feel any different than a pair of hanes and they protected the boys from fuel accelerated IEDs.
I've worn the ice breaker sports jocks for years. Nothing like a bit of merino to keep things from scorching.

Pardus wears them also as the wool on his privates reminds him of his first sexual experience.
Potomac Field Gear has been out for awhile. They are comfortable, and I prefer them to some of the other stuff that is available.
