Because each pair of our lined mittens are unique, we've organized them by size. You'll need a flexible tape measure. If you have any doubts about your size, please contact us and we'll guide you. Hand circumference is the most important measurement to get a good fit. To determine your proper size, please measure as follows:
 Size                                   Hand Circumference              Hand Length
Women's S                          7-7.25" (184 mm)                6.5-7" (178 mm)
Women's M                      7.5-7.75" (196 mm)                7-7.5" (191 mm)
Women's L / Men's S      8-8.25" (209 mm)               7-7.5" (191 mm)
Men's M                                   8-8.5" (216 mm)              7.5-8" (203 mm)
Men's Large / XL            8.75-9.5" (241 mm)    8.25"-8.75" (222 mm)
   To order custom made mittens draw an outline of your hand and wrist with the fingers together and thumb extended on a standard 8.5"x11" sheet of paper. Include the hand (through the center of the palm) circumference measurement and send that to us and we will do the rest!
