Black silicone snorkel with bottom purge system. Top of snorkel has a splash guard made out of black hard plastic which helps to protect the entry of water from minor wave splashes. Snorkel tube is smaller in diameter than most standard snorkels. Bottom base of snorkel is flexible.
The GS3164B is similar in design to the GS3162B; the difference is the stem that holds the purge system that has an angled base, the mouth piece is slightly smaller that that of the GS3162B.
This snorkel would probably fit Women or Adolescents better than most flex snorkels.
