Sizing Guide

choosing the correct Training Mask size

We recommend taking exact measurements using the method described below to determine the correct mask size for your facial structure

Your Training Mask should sit against the chin bone at the bottom of the silicon component, and on the bridge of your nose at the top, no higher than your eye line. Refer to the diagram at right to determine the best fit for your facial structure.

Measure from the centreline 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.

  1. 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)
  2. Additionally, you may also wish to check against the below measurements which represent the height of the silicon component for each Training Mask size.
    • LARGE - 13.5cm
    • MEDIUM - 12.5
    • SMALL - 11.5cm

size exchanges

You may exchange sizes for an unused product only (see our returns policy for details).

accessory sizing

Sleeve sizing is designed to match your chosen mask size, i.e. Large (L) sleeve suits a Large mask. It is possible to utilise a sleeve one size larger than the Mask size - however it is not recommended to attempt to use a sleeve smaller than the Mask size. Resistance valves are 'one size fits all'.
