Please note: Our new batch of elastic has more snap back than our initial inventory. To increase comfort we have added length to our large size and kept our small size the same, although we have worked hard to get our sizing more consistent and a little larger.
We have learned that creating 2 sizes to fit all faces comfortably is tricky.
If you are on the fence on which size to order and comfort is most important we recommend you go with the large size. You can always throw it in the dryer and it will shrink a bit.
If you find the elastic is too tight, we recommend folding your mask in half, pinching where the elastic meets the mask and stretching it out a bit. You can often gain a 1/4-1/2" of length from this which can make a big difference in comfort.
