Son suaves y duraderos. Sellan muy bien, lo cual es una ventaja en quienes usamos lentes de contacto.

I have had the mask for three weeks now.  I am a Masters swim group member and use the msk for our 1.5 hour training sessions. I had an earlier version Aqua Sphere mask and thought it was losing its elasticisity and was leaking frequently.   This is a good mask that will leak if it is not tightly pulled on your face.  The visibility is superior, the release button is a nice feature but not a significant upgrade to the lever on the ealrier Aqua Sphere.  I prefer the mask, despite needing to pull it on snuggly, because it does not leave a long lasting goggle imprint around my eyes after each 1.5 hour training swim.
This mask will fog up on its second use. I suggest using "baby shampoo" or a no more tears replacement as a anti-fog solution.  Rub on and wask off.  You will not have any fogging or deterioration of visibility.  Overall a superior product that will serve you well indoors, with the clear lens, once you pull it on snuggly and use the anti-fogging solution above.

I'm unsatisfied with the Aqua Sphere Vista Mask because of problems with fogging and leaking. I've been using the product for 2 weeks in an indoor salt water pool. I swim a mile during my workout and find that I am constantly having to adjust the mask. I like the look and feel of the mask. It's very comfortable and clear when I first start swimming. But I'm frustrated with them because after a few laps they fog over and then at about 15 laps they start to leak.

Excellent goggles! Still comfortable after long periods doing laps. Wonderful strap adjustment lets you release with touch of a button. Wide silicone base means excellent seal. Worth the high price. Highly recommended!

I get a new mask each swim season to 'treat' myself. I've been very happy with the Aqua Sphere Seal XP masks but thought I would try out the new Vista mask. I love it. It has the same great strap tensioning system as the Seal and a nice silicon skirt that forms a great suction seal to keep the water out. I've got about 10 miles of lap swimming in on it so far and no problems. The field of vision is really great - I can see what is going on underwater several lanes over which takes a little of the monotony out of swimming laps. :-)

I fell in love with this swim mask, because it had a large eye viewing area, the other small swim goggles just dig & suck into my eye balls.
These are my 5th pair I am ordering today.
But, I agree with others, that they are NOT anti fog!
Sorry , the anti fog spray does not work.  What does work is keeping them as dry and clean and free of humidity as long as you can while swimming laps...once they  fog....game over....you must keep wiping them off. I even tried my own saliva. I just got sticky,stinky, goggles! (smile)
