Exactly what I wanted,
Size: Large, Color: Light Khaki
I bought three pairs of shorts from three different companies and these are my favorite. I am going to by another pair in a different color.

Comfortable Water‑Repellent Summer Shorts That Still Look Casual and Neat
Size: XX-Large, Color: Dark Grey
I find these TACVASEN 7 Inch Casual Twill Shorts very comfortable to wear for warm weather. The polyester twill fabric feels light against the skin and does not trap heat, which makes them a good option for summer days or humid climates. The material also behaves like a water‑repellent, quick‑dry fabric, so light splashes or a bit of sweat do not linger long, and the shorts dry fairly fast instead of staying damp.
The overall look is more refined than basic athletic shorts, which I appreciate. The 7‑inch inseam, flat front style, and elastic waistband with drawstring give them a casual, everyday look that can still pass for more polished casual wear if you pair them with a polo or a clean t‑shirt. They do not look sloppy, so they work for running errands, casual outings, or relaxed social situations, not just for the beach or lounging.
In terms of construction, the stitching on my pair is nicely done, with no loose threads or obvious defects on the seams or hems. The shorts include two slant pockets and one back pocket, and one of the front pockets has a hidden zipper pocket inside, which is handy for keeping small items like cards or coins more secure without changing the outside look of the shorts. The elastic waistband and drawstring make it easy to dial in the fit without feeling tight.
Based on my experience, these shorts would be suitable for a variety of uses such as casual walks, light outdoor activities, beach days, or as comfortable everyday summer shorts that still look presentable enough for casual gatherings. If you want something breathable, quick drying, and a bit more polished than pure gym shorts, these are a solid option.
I received this item for free through the Amazon Vine program and I personally evaluate what I receive. I also pay taxes, Social Security and Medicare so I do not treat this as mindless ordering of products I will not use or fully test.

Perfect Summer Shorts for Everyday Wear
Size: Large, Color: Dark Grey
These turned out to be one of those purchases that will become part of the regular summer rotation. The fit is excellent, the fabric feels lightweight without feeling cheap, and they’re extremely comfortable in warm weather.
What I like most is that they strike a really nice balance between casual and polished. They don’t look like gym shorts, but they’re just as comfortable. The dark grey color looks clean and versatile, and the 7-inch length feels modern without being overly short.
The fabric has a smooth, cool feel and dries quickly, which is great for hot days or even light water exposure. The elastic waistband and drawstring are comfortable without looking sloppy, and the hidden zipper pocket is actually very useful for keys or cards.
Another thing I noticed is their durability that they hold their shape well and the material doesn’t wrinkle easily. They work equally well for relaxing, walking around town, travel, or casual dinners outside during summer.
Overall, these feel more expensive than they are. Comfortable, lightweight material, practical, and surprisingly stylish.

Fast drying polyester short for casual wear or to use at the beach
Size: Small, Color: Army Green, Size: Small, Color: Army Green
The TACVASEN men's 7" casual beach shorts are lightweight stretchy polyester shorts featuring an elastic waist band for added comfort. These shorts are nicely constructed and durable with no visible signs of defects out of the package. These shorts wear and feel comfortable for all types of activities or for just casual wear if you just want to lounge around. There are two average sized pockets one on each side and one zippered side pocket for added security and a rear pocket suitable for a normal sized wallet. I'm a 5'10" man and these shorts reach to the top of my knee. These shorts also have an average sized drawstring for added tightness if desired. The polyester material allows for fast drying. Overall these shorts offer a good value for wearing to most occasions.
