Next level design, build, and materials

Fit is perfect for me, but I'm a slender dude. Like others said, these probably won't fit husky types very well. I am a 36 in all pants and the waist fits just as I hoped. Length is somewhere in between modern short boardshorts and early 2000's baggy, top-of-the-knee fit. Apex shorts are like 3/4 of the way down my thigh, but I'm tall. What stands out about these shorts is primarily the material and welded seams. As you look closer, it is the lack of extra material that makes these stand out. No stitches anywhere, minimal material overlap makes for a featherweight feel. The waistband is the only part that has a double layer of fabric, but that extra stiffness makes it work just right. The tags are sewn in a spot where it is very easy to remove them with a seam ripper (just be careful and do no use scissors or razor, get a seam ripper if you don't have one).
