ExOfficio was a favorite brand of mine well before I started traveling part time professionally – their boxers particularly are major win when you’re trying to travel light. Take two pairs on a trip of any length and wash one in the shower each night before you go to bed. They’re guaranteed to be dry in just a few hours. They’re comfortable as hell, too!!!
It sounds silly, but a little savings on weight and size makes a huge difference. When I was shooting The Link I was on the road roughly three weeks a month, and reducing the amount I had to carry got to be an obsession. ExOfficio’s fast drying materials made that possible.
