*NEW* Featherweight is the same as without pocket with these extra features:

95.9% VFE (virus filtration efficiency)

Much more lightweight and breathable

A new stitching technique that won’t stick to your face when breathing. Don’t underestimate this tiny detail as it allows a cool air cushion to form between your nose and mask as you feel yourself breathing in fresh air.


Without pocket / pocket: 

Japanese medi fabric reusable mask

99% BFE (bacterial filtration efficiency)                                                                        

97% PFE (particle filtration efficiency)

Anti-viral and anti-bacterial fabric                                                                      

Water repellent 

Effective up to 100 washes

Stopper on ear loops to adjust to fit everyone

Made in Hong Kong  

Pocket: There is an option with and without pocket to insert filter. The main difference is that the mask without pocket insert will be more breathable because some people find the loose fabric of the pocket stuck on their faces when breathing.

The efficiency of the mask is not affected. As the mask is 99% BFE 97% PFE effective and up to ASTM F2100 standards for 100 washes, there is no need for an insert. The pocket mask might be too stuffy for the summer so we would suggest getting some non pockets for now, and some pocket ones for the autumn and winter months so you can see the difference


FREE SHIPPING FOR 5 MASKS or more  to the US, UK, Canada, Australia, Malaysia, New Zealand,  and the EU.

Child size: Recommended for age 3 and up. This version ONLY comes in without pocket because most children plays with their saliva often and the extra pocket traps moisture inside, making it uncomfortable for them to wear.

Child Medi Fabric Mask

This is my third time repeat order from the GreenSisters. I love the masks, bought them for my boys aged 4 & 7. Comfortable and most importantly the quality of the fabric gives me good assurance that my kids get extra protection and safer when they wear the masks to school.

Looks and works great...but...

Wife and daughters love it, both last and this rounds, but the Denim masks seem to shrink a touch after hand-washing it several times while the other option, e.g., Baby Blue, seems to retain the size. I assume it's the material but the amount of shrinkage is not significant so the masks are still providing very good coverage of the face.

The mask is light. But I think it is too short and is hard to breathe. I need to adjust the mask to get more room inside.
Overall, it us a good mask.
