I got over two seasons out of my Heli gloves. I did treat the leather once or twice over the life span.
Seriously though, it's hard to get more than a season out of any gloves. Especially if you are riding stuff where you like to drop your palm a lot. For warmth and dexterity, I really like 'em. Paying full price for a high end glove for snowboarding is not always the greatest idea. Gloves just don't last if you are snowboarding a lot.
i never had the help gloves but i work payroll on west coast and use the patrol gloves from them. they last usually 2-3 seasons and thats pretty good for grabbing everything with them. i treat them the end of the season with the balm from them.
