I've got several Prana pants similar to these and I love them all dearly. They are light weight, give proper air flow, and are ever so slightly stretchy. I wear them as often as possible which you pretty much can do so spring thru fall. I've owned one of these pairs for several years now without any problems such as tears, holes, or seams coming a part. I cannot recommend these enough. If I would give them any drawback whatsoever is that I need to several times during the day to retie the pants to shore things up but is a small price to pay for such comfortable good looking pants.
