Behind ski and binding set up, gloves and handle are next important gear for me. Without GREAT grip and connection to the handle, it is just too hard to hold on. In addition to finding great gloves, I have worn neoprene palm protectors INSIDE my gloves and have avoided torn callus for a few years now.
Masterline Masters Curves $54, Great fit, reasonable price. Nice wide wrist strap to help transfer load. Used them for about 5-6 years and seem to get a couple pair a year. With about 70-75 ski days a year I but tend to burn through the palms.
Masterline K-Palms - a bit more money and the rough kevlar-type palm material. I've tried these a couple times for improved wear, but they bunch at the base of my fingers and pinch. Favorites of some. Don't fit well for me.
Connelly Prophecy - don't bother. Poor fit and poor quality
HO Empires (not sure if they are make them any more) sort of like the Master Curves, but a bit BETTER fit.
HO 41 Tails - Better fitting Kevlar palm option. Had a couple pairs of these, and they do last longer, but stitches started to wear through in palm by end of season. Favorite gloves until I got the below:
Radar Vapor Boa $89, Ouch these are expensive. But boy are they nice. Ratcheting system on back of glove is cool, but mostly the fit and palms. NO VISIBLE wear in the palms after at end of season and still going strong. Recommend them highly, and I would say they are twice the value of other gloves that have lasted 1/3 as long.
