Traveling a lot means washing out panties. Backpacking means washing in cold water. These underwear are up to the challenge.
As advertised, they dry quickly.
This model fits so well you never think about them until you change clothes.
The construction is sturdy.
The design is smooth; they don't rub at waste, even with a pack moving on top of your clothing.
ExOfficio's bikini briefs last reasonably well.
