Sage Opala Guideshirt
This shirt is made of a quick-drying material and is nice when you want the coverage of long sleeves without completely overheating. Similar shirts seem to have a little better ventilation but at the expense of being really baggy. This shirt is a little more trim. I can not attest to the wrinkle-resistant claim. My shirt has wrinkles but maybe that will go away after it is washed.
