The TechKnit Mask
We recommend choosing a TechKnit Mask in the same way you would choose an Everyday Mask. The TechKnit Mask, however has a more minimal, sleek fit and silhouette that does not wrap as far under the chin as the Everyday Mask does, and it therefore has smaller measurements.

TechKnit Mask v1.0 and v1.1 Size Specifications
TechKnit Mask v1.0 and v1.1 (v1.1E and v1.1H). These versions of the TechKnit Mask are identical in their dimensions, but for v1.1 we reduced bulk at the outer edges to improve the fit along the sides of the mask. We also added an over-the-head elastic band option.

TechKnit Mask v1.2 Size Specifications
TechKnit Mask v1.2 (v1.2E and v1.2H). We heard your feedback on v1.0 and v1.1. We increased the size and updated the shape of the masks to improve fit and better follow the contours of the face. These masks are available with over-the-ear and over-the-head elastic bands and still feature a sewn-in filter.
