Trying to reduce the number of clothing items I need to bring to a travel, I'm currently stuck to find a good pair of shorts that are multi-functional: to be used in bed (freeballing is important to me), can be used for workout and swimming and - if all other things fail - cruising the streets. Must be fast drying (minutes instead of hours), have a waistband (instead of a belt) and should have pockets (back and/or cargo - ideally with zippers). Doesn't need to be super fashionable, dark (no-see-thru) colors preferred. Amaz... US or UK or Europe would be fantastic, but also other online shops are sufficient.
