GULL VADER Mask – UV420 Lens Premium Single Lens Diving Mask The GULL VADER is a top-of-the-line single lens diving mask, designed with a fully curved body to deliver both performance and comfort. Built for serious divers, this premium diving mask combines advanced optical technology with an ergonomic skirt design to provide exceptional fit, clarity, and field of vision. Favoured by divers worldwide, the VADER mask features a low volume design and frameless-style single lens construction, offering a wider, brighter, and more natural underwater view — ideal for both scuba diving and freediving. High-Performance Lens Technology UV420 CUT AR Amber Lens The UV420 CUT AR lens is engineered to protect your eyes from both harmful UV rays (up to 400nm) and high-energy visible (HEV) light (400–420nm). These light wavelengths are known to contribute to oxidative stress and the deterioration of lutein — a key pigment that protects the retina. With advanced anti-reflective (AR) coating, the lens increases light transmittance up to approximately 95%, compared to around 92% in standard lenses. This results in a brighter, clearer, and more natural underwater vision. The amber lens enhances contrast by sharpening edges and improving visibility in low-light or murky water conditions — making it easier to identify objects, terrain, and marine life. Super Clear Lens GULL’s Super Clear Lens technology eliminates impurities in the glass, maximising light transmission and delivering superior clarity compared to standard tempered glass masks. This ensures: Sharper and clearer underwater vision Reduced distortion Minimal reflection from the skirt when using clear silicone Anti-Reflection (AR Coating) The single-side anti-reflective coating reduces glare and internal reflection, improving visibility and allowing easier eye contact between divers — an important safety feature during underwater communication. Advanced Mask Design & Comfort Curled Lip Skirt with Integrated Strap Clip The specially engineered skirt features a curled lip design with a soft damper structure, ensuring a secure yet gentle seal on the face. This design: Minimises pressure marks on the skin Enhances sealing performance when tightening the strap Improves long-duration comfort Soft Damper Technology Unlike traditional masks that increase cheekbone pressure to improve downward vision, the VADER incorporates a soft damper system to absorb and distribute pressure more evenly. This significantly reduces discomfort during long dives. Drain Skirt System The drain skirt design improves water expulsion efficiency during mask clearing, helping to: Reduce water pooling Enable faster and easier clearing Improve overall diving safety and comfort Low Volume Design (140cc) With a volume of only 140cc, the VADER is a true low volume mask, meaning: Easier mask clearing Reduced buoyancy Lens sits closer to the eyes for a wider field of view No Center Frame (Single Lens Design) The frameless-style single lens eliminates the center frame, allowing the visual fields of both eyes to merge seamlessly. Benefits include: Wider panoramic view Brighter visual field Less visual obstruction DX Spec Mask Buckle System The upgraded buckle system allows for fine pitch strap adjustments, even while wearing thick gloves. Easy one-hand adjustment Quick release mechanism Precise fit control for maximum comfort Specifications Volume: 140cc Weight: 246g Lens Type: UV420 CUT AR Amber Lens / Super Clear Lens Skirt: Soft silicone with curled lip design Made in Japan Why Choose the GULL VADER Mask?
