Lightweight Performance Polo That Fits Better Than Expected
Color: White, Size: Small
This is a thin synthetic material performance polo, but in a good way for summer use. The material is lightweight, breathable, and dries quickly, which makes it comfortable in heat without feeling heavy or clingy. What surprised me most was the fit. A lot of synthetic polos tend to just sort of hang off the body in an unflattering way, especially thinner ones, but this one actually fits fairly well and keeps a cleaner shape instead of looking draped or sloppy. I got the white version and the color is genuinely bright and clean looking rather than dull or slightly gray like some cheaper white shirts can be. I would still recommend wearing an undershirt underneath, partly because the material is thinner and also because it helps the shirt sit and look a bit nicer overall. So far the quality seems good, stitching and finish look solid, though the real test will be how it holds up after repeated washes and heavy summer wear. Based on first impressions though, this feels like a shirt I will probably end up wearing quite a bit over the next few months.

Older than some
Color: Khaki, Size: Large
Nice for price. Wrinkles after cold water wash and dryer. Needs a touch of iron. Thin fabric good for hot days. Like color and construction.

Soft and comfortable
Color: Burgundy, Size: Large, Color: Burgundy, Size: Large
This shirt surprised me by how comfortable it is. I usually try to get cotton shirts, or shirts that at least have a little cotton in them, but this shirt is 100% synthetic. Despite that it is very soft on the skin and seems to breathe well. In polo shirts I’m usually between a medium and a large, but if I’m not able to try it on, I will usually go to the large. I did in this case, and I probably could have used the medium. But a little extra fabric isn’t really a problem with this kind of shirt, and I feel it just gives more room to breathe. There were no loose threads and the seams are even. The burgundy color is rich, and the collar has a unique pattern that received mixed reviews from my panel of family members, but that comes down to a matter of taste, and I like it. With this quality, I expect it to last through many wearings and washings.

Comfortable & Cool Golf Polo - Perfect for Hot Florida Days
Color: Navy, Size: Large
This shirt is made with a soft pique fabric that feels comfortable against the skin. The moisture-wicking and quick-dry material keeps you cool and dry, which works especially well in the hot Florida heat. It has nice 4-way stretch for good mobility, a stylish plaid collar with three buttons, and ribbed cuffs for a clean look. The shirt stays relatively wrinkle-free and is versatile enough for golf, casual office wear, or everyday use. Overall, a solid, comfortable polo that performs well in warm weather.
