As a result of my tests, I determined that this guayabera shirt is ideal for hot summer days. Made from breathable cotton fabric, it is comfortable and stylish, with a modern twist on a classic design. The shirt also has a relaxed fit that allows for ease of movement. The only con I could find is that it needs to be ironed after washing but this is to be expected with any cotton shirt .Overall, I highly recommend this shirt for anyone looking for a comfortable and stylish addition to their wardrobe..
