Great breathability and look but a serious design flaw - Outdoor Research Essential Face Mask Kit

This is a good looking mask, nice coverage, very comfortable and doesn't make you feel hot and confined. But I was a little blown away when I received it and tried to insert the included filters. There's two pockets on the side that the filter is supposed to slip in to. But they're short, not cut for the specific pockets and aren't secure. I lost a filter on the second day I wore it. REALLY bad design and I was surprised as I'm an OR fan. What I've done is buy some cheap, disposable masks and cut them to size. Shouldn't have had to do it though.
