I took this top to Africa to wear on jeep safaris and I wasn't disappointed.  It is light weight and good for layering over other tops.  I wore it consistently for 2 weeks and it held up well.  I ordered a medium (I usually wear an 8).  It was not form fitting, actually more on the baggy side but very comfy.  I loved the spf factor and how the sleeves could be rolled up.  About the only downside to this top is that it tended to get wrinkled when shoved in the backpack for a day but then I looked pretty wrinkled anyway!
