You know why there are 111 products on this year's Hot List? It's an insanely high number, the most on the Hot List since we went to nine categories in 2010. The truth is, there's just that much good stuff on the market now. We've seen darn near everything that's out there, and we've never been more impressed. The goal of the Hot List is to review the panoply of new products that we think will make a difference in your game, clubs that show us possibilities that hadn't existed. We've spent three months consulting scientists, industry insiders and players of all abilities to arrive at the game's most meaningful clubs. That includes two weeks at The Wigwam resort in Litchfield Park, Ariz., site of our annual Hot List Summit. In all, we reviewed 307 clubs to find the 111 that matter most. GolfDigest.com will be introducing new categories in the 2015 Hot List daily beginning Jan. 26.
