B2 Fit Guide
Sizing & Fit
Understanding Fit
A well-fitting mask is critical to comfort and performance. Currently B2 Mask is available in one size that fits most small and medium sized adults.
The B2 has a compact size that sits low on the nose and on the surface of the chin (as opposed to under the chin like other masks).
Take your measurements
Using a piece of string or a straight ruler, measure the distance between the tip of your nose and the point of your chin.
Make sure not to measure under the chin as the B2 Mask is not designed to wrap below the chin.
Verify your fit
If your measurement is on the upper range of the current size, then make sure you understand that the B2 has a compact fit.
If you prefer to wait for a different size, sign up here to be the first to know when they are released.
