My first mask fit pretty well but eventually I wanted better visibility and lower profile, so I bought a second one as an upgrade, not a spare. And took my time to find one that fit really really well. That gave me a spare, because things happen and the glass in masks is glass, sometimes it will get smashed. Which is why my good mask is in a Pelican box!
I don't worry about a strap breaking because I check over straps and replace them as routine maintenance. I do also have a spare strap put away, just in case. |
