Besides looking decidedly high-end (ours is bare carbon), the carbon fiber shell means a total weight of 3 pounds, 4 ounces, making it lighter than any of the other modulars we tested over the past 2 months, regardless of price. Much lighter, in fact, nearly 16 oz. in some cases. A secondary benefit of the carbon shell is that the Monaco is noticeably stiffer than most modulars when the chin bar is flipped up. Reassuring, more than anything.
