The Troy Lee Designs Ace Lite Arm Warmer is ideal when crisp morning rides give way to sunny afternoon slogs. Offering greater versatility than a riding jacket, this lightweight arm warmer brings removable, easy stashing warmth to spirited rides. Four way stretch fabric provides form fitting support and moisture wicking comfort when you're pushing hard. Smooth flatlock seams eliminate irritation on longer jaunts and high cadence efforts alike. Also, its elastic cuff and silicone gripper prevent it from slipping over time.
