Wrangler's new work shirts

My buddy showed me his new work shirt the other day, it was a Riggs twill longs sleeve button down.

 Lots of good features, dual chest pockets (wish they had flaps), button down collar, pretty hefty fabric. What Wrangler mentions (without explaining) and utterly fails to illustrate anywhere online, is that there is an impressive full side gusset  on this, as well as Wrangler's pearls snap work shirts and a few others.
So I had to go to my local Coastal Farm to sneak a photo for myself. Jeeze Wrangler, make me do your marketing for you.

If you go to all the work to design a good feature at added cost you'd think you'd show it off. I compared it to a similar Carhartt shirt in the arms-overhead-reaching-for-stuff test and it did do a little better (as in the hem had less vertical travel) but only an inch or two difference. A well fitted set-in sleeve probably does the same thing but this is a pretty bold feature for such a static brand, I approve.
