How do you plan for changing weather conditions over the course of a ride By making your outfit as adaptable as possible. For fall, many of us choose to delay breaking out our jackets and long sleeve jerseys for a more segmented approach one that includes arm warmers such as the Louis Garneau Arm Warmers 2. When worn with a regular jersey, and perhaps a wind stopping base layer, they give you insurance against the cold, and the ability to cool off if it warms up. The Arm Warmers 2 are made of Garneau's HeatMaxx fabric, a polyesterelastane blend with a brushed fleece back to retain body heat. A silicone gripper at the bicep keeps each arm warmer from sliding down and exposing a gap beneath your jersey sleeve. Flatlock seams ensure minimal friction against your skin, and a reflective logo on the forearm adds some extra visibility from the side. The Arm Warmers 2 also have a UPFSPF rating of 50. The Louis Garneau Arm Warmers 2 come in sizes X Small through X Large and in three colors: Black, White, and Red.
