Arm warmers and leg warmers are part of your basic bike equipment. With the fabric sleeves, you are flexible, well warmed and quickly dressed properly without having to lug around unnecessary ballast. It's the same with the GripGrap Leg Warmers Light. They are a good breathable insulating layer for the transitional period and cold summer days. Once you put them on, they feel like a second skin. In other words, you'll soon forget what a useful item they are for keeping you warm.
