Love the fit
Received my Halo mask.  Love the fit.  It is very comfortable and fits securely all the way around my face.  I ordered a small as I am a smaller woman and it fits perfectly.  I’ve seen a lot of comments on struggling with inserting the filter.  When I first opened up the mask, I thought it was sewn together also, but, after reading the directions (duh) it was fairly an easy task.  The curved spine down the center makes it very comfortable to breath.  Good quality.  I ordered myself a backup and ordered one in a medium for my daughter.  It is a bit pricey.  We will see how it stands up to the test of time!
