Amazing clear front and side view mask without fogging.
So far, I have used this dive mask and snorkel swimming in a large outdoor pool. Visibilty and clarity are amazing. By far the clearest mask with the best visibility I have owned after many years and several masks. Though slightly heavier than my usual “Scuba-Cat” style mask with two separate lenses, the single panoramic front piece with two small side lenses provide excellent forward and peripheral views. I can see my swim buddy alongisde without turning my head. The transparent lense treatment provides good protection from sunlight with no color aberration or diminishment.Following instructions I did not coat the inside of the lense with saliva, much less some fancy product, yet the lense remains crystal clear without fogging. I have tried this mask in cold and warm fresh water and still no fog! I will update this review after swimming in winter and diving in cold Pacific Ocean saltwater, but so far this mask remains clear.I have a large skull wearing XXL hats but thiis mask out of the box is quite loose. This mask size should be excellent for large-headed divers and swimmers but perhaps too big for smaller heads. I cinched up the straps about 2/3 way on both sides and the mask is very comfortable with little leakage even after 20-30 minutes swims.The snorkel is a long flexible “Body Glove” type with lower purge valve, easy to install and remove for storage and travel. The curve fits naturally and the mouthpiece aligns with my mouth after slidng in place. Very comfortable! The snorkel provides maximum air flow with minimal effort with a float valve at the top to keep out water. I typically mount my snorkel on the left side of the mask to provide for a right side respirator while using SCUBA. So, best to practice with a left side snorkel in the swimming pool. I encountered a problem while spinning to my left side while exercising: the upper float stopped air flow while I was rotating! No problem while rotating to the other side. This might be caused by a bit of grit left from manufacture or from the pool water but could be from the new valve design on the contoured snorkel. A nearly identical snorkel with less inate curve on my older mask never stops air flow.Simple solution is to remove the top valve as I am used to a simple open tube snorkel, attach one of my other similar snorkels or top valves, or wear-in the valve over time as the new float might just be sticky. A typical swimmer and snorkeler may not even notice this stoppage while swimming horizontal in the water with the valve only closing when you go vertical to submerge. I shall experiment with moving the snorkel to the other side of the mask and performing right and left horizontal spirals and “dolphin dives” but I was certainly surprised when the valve closed during a spin. BTW blowing slightly opened the valve, if this happens to you.Suggestion to beginners and vacation snokelers: always test new dive equipment in a safe pool before travelling on vacation, else at your hotel pool before heading out. This also allows you time to adjust straps and fit beforehand.

Love this
I have brought this on 2 cruises now. For great. Feel great.

Calidad precio perfecto
Muy buena calidad

Didn’t seal fully.
Didn’t seal well no matter what I tried and adjusted. Works ok but water seeps in slowly.
