It is made of good quality material.  It seems like it will last along time.

The junior mask did a great job for our 10 year old girls.  The two children have very different facial topologies; one is small and narrower; the other girl's face is larger and wider.  The masks worked for both of them, to my relief.  They were watertight, fog free and comfortable so both girls were able to wear them for 45 minutes to an hour at a time.  Even fighting a head current, the masks remained water free.  The wide snorkel did a very good job even under a fairly strong head current.  It had a splash guard and a relief valve, so whatever little water got into it was easily dispelled without having to take the snorkel out of their mouths, just by blowing out.
