Light low pro that pairs with the I/O
actually sized down to a medium and I have a neandrothal oblong head. Measure 23.2". I own a Giro Nine-Ten in a Large. It fits where a medium does not. The Smith Vantage and Giro Montane I need a large but they look like bowling balls..big. Never liked wearing helmets much but the Seam is comfortable, light and stylish. Have so many cool wool hats that I have had made at Wapiti Woolies over the years. Looks like they will be dedicated to apres ski. I bought the Black Boneyard model and pair it with the Smith I/O in Republic Red. Wife likes the combo and that I am actually wearing a helmet after all these years.
