I have not had mine long enough to talk about how the stitching and material will hold up, but it appears to be very nicely built and the material looks like it will wear well.  After a few dozen washings I will have to comment further.

A couple of design changes are in order however.  For the life of me, I cannot believe that any person who put these on would put anything of value in the front pants pockets.  The pockets are simply not deep enough.  If you put your keys in them, you feel as if you are going to loose them for sure.  I have to ask if anyone who may have been involved in the design or manufacturing of these has ever put these on?

Secondly, any coveralls and these included, would benefit from a pass-through pocket so that you can reach your keys in your regular pants front pockets, since you will not be able to put them in the coverall pockets.

Third, I wonder what percentage of the target audience for these is 45 plus and wears reading glasses, or anyone who may have need for securing safety-glasses like me?  A shirt pocket with a Velcro flap would really be a tremendous improvement.

I ordered a Large/Short (thanks for the short option!) and have a suspicion that the body length is for a guy 6'2".  So even though the legs may be short, the crotch hangs down and the legs are still about 3" too long for my 5'5, 29" inseam self.

I suppose it is a good thing that the body is too long, when you try to take them off, because there is no sleeves to pull on, it is very hard to get off.  If the body fit properly it would be tough to get these off your shoulders.  Now if they have a 16 year old kid try to get them off; no problem.  Let a few of the guys from the office about 50 (and not so flexible) try it.  I believe that if the coveralls were made with a longer body (as my short model) and had something (buttons, snaps, Velcro) to adjust the waist and or ankles, one could adjust the fit.

Of course, it goes without saying; any pair of coveralls would benefit by having full length leg zippers so that you didn't have to take off your boots every time you want to put on or remove the coveralls.  I would certainly pay extra for this feature.

I believe that if a little more attention was given to the design in the areas I mention, these would be about perfect.  As it is I still believe that they are nicely built for the price.
