GripSwell, without the palm pad. Leather, good quality, good fit, not too expensive (but not cheap). I also use synthetic mechanic's gloves (like MechanixWear) for rough hunting, like ducks in flooded timber. Some brands available in camo patterns, if that matters.

GripSwell available at Ivory Beads and others. MechanixWear available from Summit Racing, Jeg's, etc.
