I purchased this brand as a test to replace one of my worn Levis.  Reading the Levi reviews on this site and on others I was disappointed in the low reviews and do not want to take a chance on the loss of quality in Levis.

This particular jean is quite satisfactory.  The weight of material is adequate and compares to the much older Levis I still have.  The stitching appears good.  The belt loops are large, measuring 3/4" across as opposed to Levis at 1/2".
The Riggs front pockets are much larger and deeper than Levis and the watch pocket is huge.  The rear pockets appear smaller and more shallower.  There is a leather patch at the front righthand pocket.
The Riggs has a zipper fly and button waist, again, both appear adequate.

What remains to be seen is durability through time and use.
