It is 100% wrinkle-resistant and never needs ironing, so it is great for traveling. It is also 100% moisture-wicking and will dry quickly without even going in the dryer. The fabric is medium weight, so it is comfortable in the office or out in the field. Plus, the fabric is slightly textured, so it sits up just a bit off your skin and wears perfectly for professional, athletic, or casual wear. The slight fabric texture also prevents pilling and pulling, which tends to be a problem with 100% polyester shirts.
