If a ski and snowboard glove is too small, it will be uncomfortable.
But if your ski or snowboard glove is too big, your hand will have a hard time warming up the inside.
So selecting the correct ski and snowboard glove size is important.

How to measure for a glove:
For best results, take measurements of your width and length.
Most gloves sizes are determined by width but some people have long fingers.
Select your glove size to whichever is longer. When between sizes, go up a size.

How to measure for a mitten:
Take measurements of your width and length.
Because mittens have more room, width is the most important measurement.
When between sizes, go up a size.
