Good shorts but they run big
Size: 38, Color: Dusty Olive
I've been losing weight and picked these up in my new size (38). It turns out these are cut for a generous American midsection, and have an elastic fit in the waist, so you can (and probably should!) safely go down a size. I got mine in 34 instead and they fit great.

Great fit, functional, most comfortable shorts!
Size: 30, Color: Anthracite Camo
These are my go-to shorts, I now have five pair in different camo colors! I suggest one waist size smaller than you normally wear, (I buy a 30 instead of a 32, because they stretch and would be too sloppy if I purchased my regular size). The large open slotted pocket on the left, behind the Velcro flap pocket, is perfect for a normal sized cell phone. Plenty of utility pockets for EDC. Since these stretch slightly to accommodate movement and sitting, they are extremely comfortable. Also, my wife says they are good looking on me, so that gets an extra star!

Love the material!
Size: Large, Color: Black
Very soft and beautiful material. The size was perfect. It works well for layering and can also be dressed up. It is not clingy at all. The quality is great.

Worked well for my needs!
Size: X-Large, Color: Black
Nice thick material. I think these could be workout shirts or regular day attire. Soft, wash well, nice stretch, and arm pit gaps aren’t a so wide they look silly or sloppy. Good value for the money. True to size as well.
