We have bought two sets before the summer holiday and we have to say that the quality - as always with AL - is absolutely captivating. Our two sons are 4 and 5 years old, the silicone mask fits well even in young children and remains low over an extended period. The spectacle offers a wide field of vision and fogged very rarely and can be adjusted beyond easy. Although the snorkel could provide protection against water inlet end, as our small but so far pure Oberflächenschnorchler are, this was not a problem. Finally, the fins: they can adapt well, very soft rubber, so again, no pressure points during extended wear. The children they could easily put itself. All in all, a very high-quality and inexpensive product that you can not compare with the cheap sets. You will long enjoy it.
