The Breeze Snorkel has been conceived exclusively for Spear-Fishing. The Tube is molded in Two Types of Materials with different hardness. Three-Fourths of the Tube, in the Lower Section, is made with a Semi-Rigid Thermal Plastic Material. The Stiffness of this Lower Tube helps Avoid Annoying Vibrations during Ascent and doesn't allow for Crimping, which leads to a Reduction of the Air-Flow at the Section which is Under Pressure of Mask Strap.The Upper Tube is made with a much Softer Material. This Reduces any Sounds if Bumped against Rocks and allows for Easy Bending of the Snorkel if it becomes Snagged, thus making Cave Fishing Safer. The Contoured Breeze Snorkel is made entirely with a Non-Reflecting Satin Finish for the Stealthy Hunter. The Breeze Snorkel is available in All Black or Black/Green and is covered by a 12 month limited warranty.
