If your arm muscles are aching or cold, slip on an Arm Warmer by Vermont Fleece to warm them. Great for people with arthritis, this pair of fleece arm warmers is soft and flexible enough to fit over other long-sleeved tops. Each warmer extends 17 inches from the wrist to the biceps to keep your upper arm snug and toasty. The trademarked "Winter Fleece" material is made of non-pilling 100% polyester, which is lightweight, warm, and hypo-allergenic. Machine wash and dry.
