Soft fabric prevents chafing
Antimicrobial to resist odor
Moisture-wicking and fast-drying
Sm-3xl olive drab (low night time visibility!)
mens sizes, but I imagine the smaller sizes would fit the ladies.
These are kind of like those "if I only had one pair of underwear" underwear. Sink wash & drip dry on the shower rod for a couple hrs and you're good to go!
