I purchased this a few years ago, but I'm selling it because I haven't used it much, only a few times. I've had it professionally cleaned, and there are no significant scratches or damage. Please only purchase if you understand that this is a used item. The following is quoted from the sales site: Manufacturer Item Number: MIV9851 High-performance half-zip T-shirt with excellent mobility and sweat-wicking, quick-drying properties. This technical half-zip long sleeve is designed for activities that involve heavy sweating, such as mountain climbing. It uses Polartec Power Dry, which is lightweight and boasts high sweat-wicking and quick-drying performance. The grid structure enhances breathability while effectively absorbing sweat from the skin's surface and quickly dispersing it to the upper layers. The raglan sleeves provide a comfortable fit and allow for natural movement even during intense activities. The long half-zip design is useful for ventilation when it's hot. This single piece will accelerate any mountain sport.
