If you bought a pair of these a couple years back and loved them, like I did, don't buy these. I agree with all the comments about the material, and the way they move around. Why does Patagonia always make changes to their best selling stuff? Hello??? There is a reason people are buying it.They should add a warning to their products:"Warning! Except for the name, this is completely different from what you bought a year ago. It is made of cheaper material, and fits completely different, but hey, we make more money."The Old vs. New picture is attached, note the difference in size, they are both smalls, note the difference in the thickness of the material, the old is super thin, note the difference in the waist band and the leg bands... Cheap, worth about $8.00.
