⸻ 3D Comfort-Fit (2-layer) Mask Sizing ⸻

The Large is 4 3/8” from the top of the nose bridge to where the chin should sit. It’s 4 3/4” wide when measured flat (so that’s a half-width), excluding the elastic.

The Medium is 4" from nose bridge to chin, and 4 1/4” wide.

The Small is 3 3/4" from nose bridge to chin, and 3 7/8” wide.


⸻ 3D Filter Pocket (3-layer + Filter) Mask Sizing ⸻

The XL is 5 3/4” from the top of the nose bridge to where the chin should sit.

The M/L is 4 5/8”.

They are essentially a "half size" up from the 3D Comfort Fit (2-layer) mask design, to accommodate the filter. The M/L will fit anyone who wears the Medium 3D Comfort-Fit Mask, and folks who wear the Large 3D Comfort-Fit mask but find it roomy.

All of my masks are 100% cotton, except those with linen or cashmere content as noted, and for the elastic straps.

The masks should be ideally machine washed in medium-hot water (130 F) as a delicate (on a delicate cycle and/or in a delicate bag), or hand washed.

I suggest removing them from the washer right when the cycle is done. Smooth with your fingers and air dry to minimize any shrinking, or tumble dry on low heat.
