David is 24 and living the chic life in NYC. If you're looking for the It, trendy products for guys, my younger brother definitely has the answers. Here's what's on his wish list: "I wear a cologne called Odin 7 ($145)," he said. "It's from the NYC store (there are three). I get compliments on it everywhere I go. It's oaky and masculine. Women love it. Been wearing it for two years. It was also GQ cologne of the year."
