From Uncrate:

You can never bee too safe when traveling to unfamiliar regions. These Scottevest Travel Boxers ($20) feature dedicated iPhone and passport pockets — the better to keep them safe during your adventures — as well as more normal features, such as a button fly, anti-microbial odor- and stain-resistant treatment, and Nylon and Lycra construction that allows them to dry quickly, hopefully helping to avoid the dreaded “swamp ass”.
