Unbeatable women's summer shirt for the mountains. Lightweight, well cut and breathable, these are the basic parameters of this T-shirt. The basic material is 100% PES, which has a 4% addition of Lycra elastic material in the ventilation panels. The whole shirt has antibacterial treatment Polygiene and of course UV protection UPF 50+ (20+ mesh parts). The most technical part of the shirt is the collar, which is lined. The lining of the collar is pulled up over the upper part and protects the neck from chafing from the straps of the backpack or vest during long runs in the mountains. The central zipper allows for better thermoregulation in the heat and uphill running. The zipper is clearly the hardest part of the shirt, it's finished to the garage so it doesn't bite into the nape of your neck.
