This issue on the Amazon has a good one.
On the last couple of pages it has a good pic of a MOF. Next to it is a COF.

And your feelings abour DIR, HID, BP/W AIvs Non AI.......When you have been in the water for more than two hours....Aww, never mind.Penguinboy:Haha you replied ahead of me! True point though - always around the neck or next moment it is gone.
On this issue - I think NMOF is better when you are in the water, and really the mask should only come off on land or on the boat. If theres a wave or you start to sink (whatever reason!) or for anything, and your mask is on your forehead suddenly your eyes are underwater or stinging from salt and trouble starts. Why take your mask off when you are still in the water. No reason to do it and here is at least one not too.
Stirred up trouble here haven't I
Edit: Hobster got my point in before me! There was me thinking I had come up with an original point![]()
