The tagline for the Give-N-Go line from ExOfficio says it all: "Seventeen countries. Six Weeks. One pair of underwear. OK, maybe two."
It sounds gross, but trust us, these undergarments do exactly what they say. Everything from the line is quick-drying, allowing you to wash a pair at night that will be ready to wear by morning. And they are made with a microbe shield that controls bacteria and resists odors. We're biased toward the boy shorts ($20).
