When it's a little chilly on the first tee, we recommend a white cotton turtleneck. When it's downright cold, a cashmere version like this flannel grey Harrison* (on deep discount) should do the trick. When it's snowing, as it was at the Accenture Match Play Championship in Tucson this weekend, we suggest you book a flight to somewhere where it's not snowing and play there. (There are plenty of nice courses in Maui, where it shouldn't start snowing until at least 2013.)
Whatever you do, though, never wear what Martin Kaymer, the world's newly crowned top-ranked player, was wearing this weekend. On Sunday's broadcast, we learned the hideous scarf-like accessory assaulting his neck is a UV Fishing Buff by artist and retired Florida Keys fishing guide Vaughn Cochran.
The UV Fishing Buff is made from Coolmax Extreme fabric and features a black fly fishing lure pattern that we're pretty sure is guaranteed to actually repel oysters and mollusks, not to mention creatures with actual eyes. The only time to wear such a thing is if you're skippering the S.S. Toolbag. Never ever wear one a golf course.
* Harrison's quality is as variable as Bubba Watson's golf swing. Some of their sweaters are our favorites; others barely make the Vietnam Veterans clothing donation bin. Inspect carefully before committing.
