Great Summer Look & Very Comfortable Fit Perfect Vacation Shirt for Tall Guys
Color: Khaki, Size: Large
I am very pleased with the quality of this shirt. The material is incredibly soft and has a nice weight to it, making it feel durable yet breathable. It features a moisture-wicking property that makes it a clean-looking, essential summer shirt, especially for those warmer days here in Utah. I really like the tan color; it looks great and pairs easily with a pair of jeans, nice shorts, or even flip-flops and sandals. At 6'5" and 260 lbs, finding a shirt that fits my height can be tricky, but the size fits me pretty good and the fit is actually better than some other extra-larges I have tried. Even with a little bit of a belly, it is very flattering and the soft material feels great against the skin. It is slightly shorter than some other XL shirts, but it still works well for my frame. We are heading out on a cruise this week, and this is definitely going to be my go-to shirt for checking out the ship and staying comfortable in the sun. The washability is another high-quality factor—I always wash things before wearing them, and this one didn't shrink much at all. Everything from the color to the texture stayed perfect right out of the wash. Overall, I hope you enjoy this shirt as much as I did because it really is a well-made and good-looking product!
