Wild River clothing is built with all the performance features you need to be active and comfortable while enjoying your outdoor adventures. The Wild River Travel Shirt features Mosquito repellent fabric, a highly effective Permethrin based technology which is environmentally friendly and will last up to 30 washes! This shirt is rated at UPF 50+ and is very hard wearing. It has a low moisture absorbency, so it doesn't take on water which means its quick drying and it doesn't absorb sweat. A great advantage over cotton which if it gets wet,stays damp. With the 10% Elastane, it has enabled us to get tremendous stretch in this garment which gives the wearer a lot of comfort while also being wrinkle free.
