Cressi Alpha Ultra Dry Snorkel

Cressi Alpha Ultra Dry Snorkel (included in package)

Cressi Alpha Ultra Dry Snorkel helps you breath with confidence and explore the underwater world. The Alpha dry has been streamlined to reduce drag from the water and as the name suggests it is great for snorkelling, keeping the water out of the snorkel when diving below the surface. The Alpha Ultra Dry snorkel has a patented valve in the top of the snorkel which closes when under the water preventing water from entering.

A drain purge valve also means any splashes of water entering the snorkel while at the surface are easily cleared.

  • Float Valve System
  • Super Soft Quality Silicone Mouthpiece
  • Streamlined Design To Reduce Drag
  • Angled Mouthpiece To Reduce Jaw Fatigue
  • Low Purge Valve For Quick Water Expulsion
  • 2 piece, quick release, snorkel clip
Cressi Big Eyes Evolution Crystal Mask | Black

Cressi Big Eyes Evolution Crystal Mask (included in package)

The Cressi Big Eyes Evolution Crystal Diving and Snorkelling Mask features Cressi's patented Crystal silicone which makes the seal of the mask exceptionally soft and comfortable. It is also a much clearer silicone than the standard silicone found in other masks, so more light travels into the mask for a brighter dive or snorkelling experience.

The trademark angled lenses of the Cressi Big Eyes provides increased downward vision, while the EVOlutionary structure of the mask frame and skirt enhances the overall experience.

The internal volume of the Cressi Big Eyes Evolution Crystal is also reduced giving the feeling of enhanced vision

Superlight and easy to adjust mask strap buckles which can be pivoted to provide the perfect angle and position on the face.

Even the mask strap gets a makeover making it really comfortable on the back of the head to enhance fit and comfort.

  • Crystal silicone.
  • Low internal volume.
  • Raked lenses for wide field of vision.
  • Ribbed skirt design for better fit.
  • Easy to adjust mask strap and buckles.
  • Supplied with protective storage box.
