Dangerous product! very cheap glass!

This mask was used less that a week before the glass shattered in my son's face when he jumped into the pool with it! Words cannot express how angry and disappointed we are in this dangerous product. The tempered glass is obviously of very very poor quality, and can shatter in a child's face! We were lucky his eyes were closed when this happened and we avoided the worst, so cleaning bits of glass from my pool floor was a much better scenario than having to take a child to the emergency room with shattered glass in his eyes!! Don't buy this mask, it's is cheap and dangerous!!

หน้ากากดำน้ำใส่ดี กระชับหน้า

ฟิต กระชับหน้า น้ำไม่เข้า ไม่หลุดง่าย ไม่ค่อยมีฝ้า ใส่สบาย ตรงสายมีห่วงเย็บใส่ snorkel ได้เลยในตัว แต่ตำแหน่งเวลาใส่ snorkel กับสายคล้อง ทำให้ snorkel ไปอยู่หลังหู ทำให้ต้องขยับบ่อยๆ

ขอบคุณมากนะครับ สำหรับการรีวิวสินค้า

My friend and I bought the same type of freediving mask, mine was small and his was medium. I'm surprised to when i noticed that his was tempered glass and mine was plastic. Not to mention the product description is different from the code and we had to ask for the assistance of one of the staff.

Pleasantly surprised

I was sceptical at first about this mask because of the low price. I have used this mask several times now and can honestly say that it is great and does not leak (for me). I made sure I tested the mask at the shop for a correct fit and could not be any happier with this mask. Great value and great quality.

Additional Product Information


Diving mask (skirt)

  • 100% Silicone


  • 100% Polyester cationic

Diving mask (frame)

  • 100% Polycarbonate

Diving mask (lens)

  • 100% Mineral glass


For children from 6 to 10 years, we recommend size S. From the age of 10, size M is recommended for thin faces and size L covers larger faces.


Silicone is an extremely flexible material. A silicone skirt fits flexibly to the contours of the face, creating a watertight seal.

Tempered glass lens (sizes m and l), polycarbonate lens (size s)

Tempered glass is 2 to 5 times more durable than traditional glass. It is more scratch-resistant than a polycarbonate lens. In case of a major shock, it breaks into small pieces, reducing the risk of a major accident. For the safety of children, size S is of polycarbonate.


Mask certified as compliant with safety requirements according to European EN 250 standards. Certified by the INPP (French professional diving institute).


This mask contains no materials containing PVC.

What is the difference between freediving and snorkeling?

At Subea, the Decathlon diving brand, we decided on a simple way to define the difference between our freediving and snorkeling products: From the moment you hold your breath and swim under the surface of the water even a few meters, it is freediving. Conversely, if one stays on the surface, this is snorkeling.

What is the subea brand?

Tribord Diving is now called SUBEA, the Decathlon brand dedicated to underwater sports (snorkeling, scuba diving, spearfishing and free-diving). The markings on all our diving products will gradually be replaced. Why SUBEA? Because: "SUBaquatic Experiences are Amazing"! For more information:
