In severe conditions, a layered system is really important, with the number and type of components being determined by the activity and expected weather. Needless to say, each components must be of a size to match the others.
Often, but not necessarily, this needs to be a fingered layer if you need to use your fingers. Otherwise, fingers keep warmest if they are in a mitt, where they provide each other with warmth.

As an outer layer of two or three, this should always be a mitt. Large, easy access for the hands is an important requirement, which is rare to find in normal production products (apart from the Snowsled handbags, shown). For safety sake, it is useful to hang them around the neck, from loops on the cuffs - you can’t risk hand protection blowing away!
The Snowsled ‘handbag’ system allows for very efficient management of hand protection.
