Dakine has reworked their Ventilator glove for 2012 and added 3mm thick palm padding. These might be what you’re looking for. When my wife started riding DH she was worried about the lack of padding in her gloves as well and settled on a well fitted pair of women’s Fox Dirtpaw gloves. They have served her well for the past few seasons. For myself, I’ve enjoyed Fox’s 360 Vortex and Troy Lee’s GP glove this season.
