Hats: Measure the circumference of your head using a measuring tape. Wrap it around your head at the point where the hat will sit (about an inch above your eyebrows).
Gloves:
Hand Circumference: Measure the circumference of your hand by wrapping a measuring tape snugly around your knuckles.

Middle Finger: Measure from the tip of your middle finger to the base of your middle finger.

If you're on the borderline between two sizes, order the smaller size for a tighter fit or the larger size for a looser fit.
