One of the most common reasons your hands and fingers get cold while wearing gloves is because they do not fit properly. The body heat from your hands is what keeps you warm, so the right amount of space needs to be available for this heat to circulate. Gloves that are too tight don’t allow for this circulation at all, while ones that are too loose have too much space in them that cannot be heated well. Ski glove liners help provide additional warmth and could be the solution for you. Additionally, perhaps mittens, rather than gloves, may be a better fit if you’re constantly cold.
