Sherwood has brought back the classic “J"-style snorkel design for those who like a simple, yet functional no-nonsense snorkel. The onyx has a professional matte black finish for that stealthy look. The onyx has been designed for spearfishing, free diving, and in many cases is used for scuba because of the low profile nature of the Onyx. The contoured tube hugs the divers head for perfect hydrodynamics and less drag. The onyx has an easy-to-attach and detach snorkel keeper for attachment of the snorkel to your mask.
