Sauron Mask for Spearfishing and Deep Freediving

The Sauron mask is made entirely from premium-quality matte hypoallergenic silicone, specifically designed for spearfishing and deep freediving. The frameless construction allows the skirt to flex under pressure, adapting perfectly to the natural contours of the face and ensuring a better seal and greater comfort during dives.

This feature is essential for maintaining an optimal seal at the greater depths typical of spearfishing, where external pressure changes the shape of traditional underwater gear.

Technical features

• Matte hypoallergenic silicone skirt for a soft-touch feel and maximum fit
• Frameless design for greater flexibility and adaptation to the face during descent
• Ultra-resistant tempered glass lenses for safety and durability
• Wide field of view with exceptional lateral visibility, making it easier to perceive the underwater environment
• Lightweight, minimalist design to reduce internal volume and make equalization easier during dives

Benefits for freediving and spearfishing

The Sauron mask is ideal for deep freediving and spearfishing thanks to its adaptability and direct skin contact provided by the soft silicone and absence of rigid parts. The wide lateral field of view helps the spearfisher locate the target, while the high mechanical strength of the tempered glass lenses contributes to greater safety during dives.

The combination of selected materials ensures long-lasting comfort and durability, making it suitable for dives dedicated to freediving and spearfishing.

C4 Vertical Up Two-Piece Freediving Wetsuit

The Vertical Up wetsuit is specifically designed for freediving, offering advanced solutions for spearfishing and freediving. Made of separate jacket and pants, it is available in two neoprene thicknesses: 3.0 mm and 5.0 mm, to suit different needs for thermal comfort and mobility.

Materials and Construction

Made from open-cell neoprene on the inside with an outer stretch Milk Silk lining, the wetsuit provides high two-way stretch and abrasion resistance. The neoprene used is 100% limestone-based CR, TÜV certified for the absence of harmful substances such as phthalates and latex, ensuring user safety and environmental responsibility.

The material features a Type C (0-2) hardness range and 600% elongation at break, ensuring excellent elastic recovery and compression resistance.

Anatomical Cut and Comfort

The Vertical Up wetsuit features a pre-shaped anatomical cut with a reduced number of panels and seams, improving softness, fit, and stretch. Seams in key areas such as the shoulders, knees, and elbows are completely eliminated to reduce friction and drag during finning and underwater movement, promoting greater freedom of movement and comfort.

The panels are hand-glued and blind-stitched, while the jacket features a Lycra finish to protect the wetsuit from damage during donning and doffing.

Technical Features and Variants

• Jacket closure: plastic beavertail toggles for the men’s model, Velcro for the women’s model
