Specially designed for trekking and hiking, the MXP from Millet is the glove for the mitten of the same name.
Offered on its own, this glove can be worn in addition to the mitt in really cold weather or on its own as a thin, agile glove. It's windproof and waterproof, and made of a very soft and durable softshell fabric that wraps around the hand nicely without restricting its freedom of movement.
For even more performance, it adds a touch screen compatible zone and velcro wrist adjustment.
