- A button that just "clicks". Most pants I usually owned had a traditional pants button. Those more expensive ones had buttons that just "clicked". Away goes the worry about a button falling off while you are on the go. - Pockets with hidden zippers: My pants have pockets and in those pockets are smaller pockets with a zipper. Perfect to store things that are small and easily lost.
There are more "features" but those are the important ones. The most important feature is just the material that is used. I barely feel it. Also the company that makes those pants makes other things as well. I ordered a lot of cloths by now and the amazing thing is that everything they make fits me perfectly. I don't know how they do it… When I usually buy pants I have to try on like 10 pants to find one that fits. Even if I pick the "correct" size.
