You might assume the Swix Women's Banner 3 & 1 Mitten has a removable liner since you see 3-in-1 jackets with the same design. That's not the case; by 3 & 1, Swix means this mitten has a 3-finger design (3 fingers, 1 finger) for Nordic skiers who want the warmth of a mitten and the convenience of having an index finger available to use a smartphone.
