SIZE GUIDE

We recommend you to combine the Weight Measurement and Eye-Chin Distance Measurement to pick the right size.

Instruction for Eye-Chin Distance Measurement:
You need a wall mirror, a ruler, and something flat (like a book).

  • Look straight ahead into the mirror, keep your head upright.
  • Place the ruler, starting from your lower eyelid, straight down and parallel to the mirror.
  • Meanwhile, with your mouth closed, hold the book parallel to the ground and let it touch your chin.
  • Now you can check the number at where the ruler crosses your book.
