This snorkel features a semi-dry top (meaning, some water may enter when it is submerged), and a drain valve at the bottom.  The snorkel is fitted with an adjustable clip for attaching to your mask strap and features a soft flexible silicone hose to add comfort when using.

The bottom purge valve is activated by blowing out sharply, this will clear some/all of the water in the snorkel allowing you to breath again.
