Easy style. Itís a phrase used in the Alps to describe the no-stress, go-with-what-ya-got mountain lifestyle thatís existed for generations there. It also aptly fits this crisp yet casual short sleeve button up. The Columbia Sportswear Men's Declination Trail Short Sleeve Shirt features a wonderfully textured modal fabric in a series of savvy plaids and cool, deep colors. A security pocket at left chest closes with a button to keep Metro tickets and Fourth of July pinwheels in check.
