    5 Review Stars By Doug

    The fit on this mask is perfect and the field of vision is unbelievable.  The nose purge is a really nice feature.  I purchased one for myself and for my wife in anticipation of our snorkeling in Hawaii later this year.

    I think these are the best Snorkeling Mask on the market and The SwimOutlet has a good inventory, best price and most prompt service.

  • 6/18/2012 feels large

    3 Review Stars By Lynda

    This may be worth more stars to others, as I can't speak to how this performs in the water. I ordered the yellow, which is cool and matches the picture, but the info on the mask suggests that it fits narrow faces.  My husband and I both tried it and found it too large.  Not only was it too wide for me, but it also came down too low on my lip.  It just felt large overall.

  • 8/1/2011 Perfect Mask

    5 Review Stars By kt

    This is the best mask I have owned.  It fits perfect, in fact, I had to purposely open the mask to fill with water to check the purge valve which by the way, worked without a flaw.  I have the straps adjusted very loose but the fit is so good that it doesn't leak at all.
