1) It's horrible for working out: Silk has a tighter weave than cotton, and so this mask is fine for casual wear, but horrible for working out since its not as breathable as our older versions of the Aplu mask.
2) Hard to use with a filter: Due to the same tight weave issue, the mask is not as comfortable to use with a filter when compared to our cotton based version.
3) One time release: One of our constant struggles is that we never have enough of our materials to produce more products; well, with this mask, we only have enough copper silk blend to make 400 masks. We're unlikely to make more in the future because of the high costs.
4) No neck strap option: Due to the limited production amount and the tight weave, we're not able to produce neck strap options.
