I take this shirt a lot and for a long time. Quite surprisingly, the anti odor effect. Add to that a kind stain protection. Even problematic things can usually quickly and at best removed with water. So one wonders how long it actually does not have to wash. This can be of great value while traveling. In addition, it is extremely robust, and nothing remains hanging easily, such as thorns. Here by the (mosquito) dense tissue rather windproof but still breathable (with ventilation functions) and very quick drying. Portable in some colors quite well outside the wilderness. Even the bags are very useful but not overdone. The sleeves can be up your sleeves with fastening on the inside. So also to wear short sleeves. Never in 40 years of active "outdoor activity" had something better.
