I fell in love with Columbia's long sleeved silver ridge shirt and was hoping for a lighter weight version for summer. The long sleeved one is dressy enough to be tucked in and worn at work and I was hoping for the short sleeved style to be the same. This shirt is definitely breathable and comfortable on those hot and sticky days. It's great for hiking, camping, and other outdoor activities. However, it is a completely different style and fit than the longs sleeved one. This shirt is rounded and longer in the back on the bottom, which is flattering stylish (but not at all like the long sleeved version). I have muscular shoulders, but am able to wear the small in the long sleeve. This one I had to exchange for a medium to avoid the tightness and tugging around my shoulders. Because I had to up the size, the rest of the shirt fits really loose. The big zipper down the dress pocket also makes it too casual to pull off wearing to work. If you just want a great shirt for summer outdoor activities, ignore my whining about it being different than the long sleeved one, because this is a great shirt!
