Going Commando, and Packing Extra Socks
It is important to keep your body dry. You want to avoid having any moisture near your skin for any length of time. You can avoid this by wearing less clothing in some regions and rotating into dry clothing for other regions.
Skip the underwear and use that extra space for more socks in your bug out bag, get home bag, or backpack!
We can not verify that commandos forgo underpants when they are operating in the field, but the practice is by no means limited to just soldiers and special forces. With limited backpack space and minimal opportunities to bathe or change clothes, some people have decided that clean underwear might be more trouble than it’s worth.
Going underpants-free may increase ventilation and reduce moisture in a soldier’s uniform, which in turn minimizes the chances of getting a rash or crotch rot, aka Tinea cruris, a fungal infection of the groin.
Whether or not they wear underpants, many of the soldiers use Gold Bond Medicated Powder as a preventive to avoid ailments of their nether regions
As you can see moisture, dampness or wet conditions can cause serious health concerns. mitigate these concerns by going Commando, while packing some extra socks!
