Warmth, durability, and dexterity define the 509 Fisticuff Trigger Finger Mitt. You can fight us if you think we’re kidding. Super warm thanks to Thinsulate™ insulation on the back of the hand and the palm, combined with a waterproof lining, these short gauntlet mitts get their biggest benefit from the trigger finger, which adds dexterity for reaching the brake when you need it.
