I purchased this a few years ago, but I'm selling it because I haven't used it much, only a few times. I had it professionally cleaned, and there are no significant scratches or damage. Please purchase only if you understand that this is a used item. The following is quoted from the sales site: Manufacturer Part Number: MIV9025 High-performance transfer layer 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, a micro-structured knit material that provides a natural feel and excellent comfort even during intense movement. It is lightweight and boasts high sweat-wicking and quick-drying performance. The grid structure on the back enhances breathability while effectively absorbing sweat from the skin and quickly diffusing it to the upper layers. The long half-zip design is useful for ventilation when it's hot. With various features such as a chest pocket and UV protection, this single layer will accelerate any mountain sport.
