Repironics full face blue comforgel sizing help
The sizing template is odd, and the reviews say it runs small but I wanted to see what others thought. According to the template Im in between small and medium. I lean toward the small since a medium simply makes it too tall and I know this will cause eye leaks, however the small sets on the edges of my mouth. This is using the paper template. Any suggestions? Thanks
