I've been happy with the Winter Elites, from Tourmaster. They are not particularly thin in the palm, but the heat from the Hot Grips just takes a minute or two longer to get there. I still have to turn the heat down after 10-15 min. when they get scalding. The leather claims to be waterproof. (in 40+ years of riding, how often have I heard that claim?) but in a clever pocket sewn into the gauntlet is a thin, rubberized, nylon "over glove", which is actually waterproof. It's sewn in & folds flat, so you never know it's there, but when needed, it's there, not back on the shelf in the garage. Nuttin worse than hands that are wet and cold.
