Ex Officio has gained quite a reputation in the wonderful world of underwear, having become one of the best-known brands offering high-performance, moisture-wicking, quick-dry underwear for men and women in a number of styles, and having been taken to countries all over the world. Ex Officio wicking underwear is relatively inexpensive (compared to some of the pricer brands), and can often be found on sale.
The material itself is made of mesh (though not see-through) nylon and spandex, and lives up to its reputation as quick-drying, wicking and easily manageable. This is the kind of product that can be worn all day, washed in the sink at night, and ready to go by morning.
Keep in mind that the Ex Officio underwear is generally sized to be a somewhat relaxed fit; size down if you want the fabric to fit more snugly in order to stay in place.
Ex Officio has been expanding it's women's travel underwear selections for quite some time now, to the point that the ladies have more style options at this point than the gentlemen. So, maybe someday, no one will have to say "it's just travel underwear, it doesn't need to look nice." Because fashion and function need not be mortal enemies.
