3. The shell glove – extra protection when needed

The shell glove acts as a reinforcement layer when the cold sets in, conditions turn wet, or you stay still for longer periods. It creates an additional layer of insulating air around the hand, significantly increasing warmth. Combined with a liner, a shell glove can provide up to 50 percent more warmth than using a base glove alone. It takes up little space and is easy to pack away until you need it.
