As you all know by know, my husband is a golfer. He golfs as much as he possible can. He golfs until they take the flags off the greens to protect the greens from the potential harm of folks walking on them when they're too frozen. He keeps golfing until the course is buried in snow. And then he starts again as soon as you can see the fairways.
When you're this obsessed with golf, there will inevitably be days when you arrive at the course thinking you've dressed appropriately, only to have the wind kick up and make you wish you'd put on that turtle-neck after all. Unfortunately, when that happens, adding a jacket doesn't really solve the problem.
I offer Cantigny (named after a golf course in Illinois):
Though this cowl/turtle was designed for a golfer, it works as well for those who never hit the links. In cotton, like the original, it will keep your neck as warm as that cotton turtleneck. In wool, it'll be even warmer. And it doesn't get in the way when you open up your jackent (as a scarf would do). This simple textured pattern manages not to look too feminine, so even the guys on your list will wear it.
Even though I designed it for a golfer, I know several singers who might find it helpful. In fact, those of us who are prone to losing our voices with seasonal colds and such may also find one nice.
The original was knit using 180 yards of Fortissima Cotton, but any fingering weight yarn will do.
The cowl is worked top down, with a bit of extra ribbing on the "corners" to help keep the cotton snug against the wearer's neck, even after being stretched out to go over his head.
Better still, it's already in testing, and the pattern should be available for purchase very soon.
This diamond brocade stitch pattern helps trap warm air inside.
