I have two pair of these shorts, and I'm sure I will be buying more.  They're the most comfortable shorts ever, weigh next to nothing, are durable, and they're perfect for packing and traveling.  They don't soil easily, but if they do you can wash them in your hotel room and hang them near the air conditioner and they'll be dry (and relatively wrinkle-free) in a jiffy.  They're my go-to shorts for hiking and biking.  I've owned them for about a year and they show no signs of deterioration.  I highly recommend them.
