I have worn this jacket for 17 years. It wears well in a wide range of temperatures, comfortably handling temps from the 30's to the high 70's. I hand clean it and treat it annually. The vents are well placed and effective. All zippers still operate flawlessly. The reflective material still reflects brightly. My son was so impressed after trying other jackets, he bought the same model. The only thing wrong with mine is a thumb sized hole in the right hand pocket. not too bad after 17 years and tens of thousands of miles, in all weathers, including snow and ice. I keep looking at newer jackets, but stop when I realize that none of them function as well as this one. If mine wears out within the next ten years, I'll just get another one just like it.
