High-quality hardware, silicone boot, seals, and stainless-steel t-bolt clamps ensure optimum durability and ease of installation.

Great fit, simple style, and comfortable for all-day wear
Style: 7" Swim Trunk, Color: Aqua Blue, Size: Small
These swim trunks are a solid find—comfortable, well-made, and true to size. The 7-inch length is just right: not too long, not too short. They dry fairly quickly and have a mesh lining that’s supportive without being annoying.
The style is simple and classic, and they’ve held up well through swimming, beach trips, and even some light hiking. Great value for the price.

Not quite as good as top name brands but pretty decent so far for the money
Style: 7" Swim Trunk, Color: Black, Size: Large
I compare these to the Columbia version with similar design.
I ordered the large, which is my Columbia size. I note that the Amazon version was slightly tighter in the waist and the lining was significantly tighter in the legs. The elastic bands are both well structured and not flimsy.
I live in Florida and I wear these swim trunks as my everyday outdoor shorts, whether working in the yard, biking, walking, or whatever. I note that when I tried to wear these in my exercise classes, the legs tend to stick and not slide up the legs when I squat, which is not a problem with the Columbia shorts. Lest you think it unfair to compare these two brands, Columbia puts their shorts on sale a couple of times a year for about the same price. Of course, you have to pay attention regularly to their website and it doesn't help if you need shorts now.
I will continue to use these shorts for outdoor work and activities and they seem to be holding up fine for now. Next time I will probably get the XL for comfort if Columbia doesn't have a big sale (unless I can manage to lose a little visceral fat I have collected the last few years!).
One other positive and one negative. I like that the black shorts have a black tie string, but the blue pants have a white string which shows dirt and looks a bit cheaper than if the string was blue. White is fine for swim trunks, but when they are used as all purpose volley shorts it doesn't show well with white string.
I saw some complaints in the comments saying these shorts were not quick drying. I note they are every bit as fast drying as my Columbia and Nike shorts which are advertised as quick drying. As you might imagine a few hours working in the Florida sun I can sweat a ton so I can certainly judge drying speed.
