Silent is meant to be adjustable, and comfortable! The "wings" move in and out depending on how much pressure you need to Breathe Easily.
Silent's sizing is based on the measurement of your nose FRONT TO BACK. The smaller curves are meant to anchor in the internal divot in the tip of your nose-what is called the "cone". This anchor point is what keeps Silent in place without tension.
Determining your size:
- Measure your nose in SIDE PROFILE, from the tip of your nose to the crease where your nostril meets your face.
- If your measurement is 23 mm (0.85 inches) or LESS, order a small. If 24 mm (0.9 inches) or MORE, order a large.
No measuring tape? No problem!
Just use a standard US quarter and dime. A dime is approximately the size of a small, and a quarter approximately the size of a large.
