Review on Portable Neoprene Mask Storage Case with Zipper & Carabiner Clip - Ideal for Kids, Women, Men - Black by Nolan White

I bought these for an upcoming trip and they definitely fit a variety of different caliber masks. For example I have several masks that come with a metal nose piece to hold it in place and this cover keeps it from being completely crushed. As this is a pack of three I also want to use some masks at work and keep them in case I need to change my mask or need a backup. I also bought these for my upcoming hike and definitely see uses for them.
