A base layer for your hands; this simple mission is what the Assos insulatorGlove L1_S7 Gloves are all about. They're made of a combination of Assos RX and RXQ fabrics that should fit your hand like a second skin. RX is the denser fabric, and it is used for the thumbs and wrists. The RXQ stretches better and is used for the palms and backs. The palms are also covered with anti-slip gripper material.The core design of the insulator S7 Gloves is that of versatility. When worn on their own, the gloves are perfect for regulating finger temperature in 50 to 60 degree weather. But using the same principles of layering, Assos recommends pairing them with a dedicated shell glove like the Assos rainGlove, earlyWinterGlove or fuguGlove to best protect your hands from rain, wind, or the winter chill. As a base layer, the insulator L1_S7 Gloves work to trap warm air and transport sweat vapor from the inside of the glove to the outside so that your hands stay warm and dry.The Assos insulatorGlove L1_S7 Gloves come in Black Volkanga. They're considered climaRange 1 Spring, 57-72 degrees F (14-22 degrees C) and climaRange 4 Fall, 46-61 degrees F (8-16 degrees C). Sizes run from XX-Small to X-Large.
