Choosing the correct mask size
Measure from the centerline of your face at your mouth to at least 1 inch (2.5 cm) past the outside corner of your mouth (you might want to ask a friend to assist you). The outer edge of the Training Mask should sit against your face at 1 to 1.5 inches (2.5 to 3.8 cm) outside the corner of your mouth.
Choosing the correct mask size
Double the measurement you have taken and match to the best fit from the below:
• Large: 5 inches (12.7 cm)
• Medium: 4.5 inches (11.4 cm)
• Small: 4 inches (10.2 cm)
Choosing the correct mask size
Below is a general guide based on body weight (note that facial measurements are more accurate for ensuring correct fit):
• Large: 250-300 lbs
• Medium: 150 - 249 lbs
• Small: 100-145 lbs
