You can wear these merino wool liner gloves on their own when it's not extremely cold, or put them under other gloves for extra warmth. When wearing, make sure they fit your hands well for better dexterity. For cleaning, hand - wash them in cold water with mild detergent. Don't wring them out forcefully. Let them air - dry flat to keep their shape. Avoid exposing them to direct sunlight for a long time as it may damage the wool fibers. Also, don't use bleach or fabric softeners as they can affect the quality of the merino wool.
