I have been very pleased with the sibling product which does not feature an extra pocket, but when I needed a new pair of pants I chose this item because of the extra pocket. I'm very glad I did, for I really use that extra pocket. Most other people seem to use it for their cell phones, but I use to hold an easily accessible array of different writing pens. I work in food service in a kitchen, and I need 4 different pens to write on various surfaces. This pocket allows me to keep them in order and to access them without getting tangled up in my apron. The other really huge benefit of these pants, and similar twill Dickies Pants, also, is that they line dry very quickly. I am very poor and do almost all my laundry by hand in the bathtub, and these pants wash and dry by hand very well. Dirt comes out easily, stains do not set (easily), and they line-dry (by hanging up) overnight. Excellent!
