Gull Mantis LVR Dive Mask

Gull MANTIS LVR Dive Mask – Compact Fit with Advanced UV420 Protection

Derived from the legendary Mantis LV, the MANTIS LV-R (Reloaded) features a more compact overall design, enhanced sealing technology, and refined styling. Precision-engineered and Made in Japan, this model is equipped exclusively with UV420 AR lenses and Gull’s latest Comfort-Fit Technology silicone skirt. The MANTIS LV-R delivers more than just a smaller fit—it is a complete performance upgrade for the discerning diver.

Design Evolution & Performance

The MANTIS LV-R integrates a lighter, more compact structure while maintaining the signature wide field of view and low-volume design. Precision-engineered in Japan, it delivers exceptional build quality, durability, and meticulous attention to detail.

• Volume: 110cc

• Weight: 220g

• Made in Japan – premium precision manufacturing

• Compact twin-lens design

• Low-volume construction

• Wide vertical and horizontal field of view: The optimized lens inclination angle and shape extend downward visibility, allowing clear vision down to chest level, where most diving tasks are performed.

Comfort-Fit Technology (Next-Generation Seal System)

1. Reinforced Damper: Facial movement can compromise a mask seal and cause water leakage. Reinforced dampers stabilize the skirt edges, preventing flooding even during strong facial movements.

2. 3D Leak Guard: The inner skirt features a three-dimensional structure designed to seal effectively around natural facial creases, such as laugh lines, maintaining a secure fit even when using a snorkel or regulator.

3. Temple Line Design: The skirt trim is shaped to avoid interference with the hairline near the temples, significantly reducing the chance of water leakage.

4. Easy-Pinch Nose Pocket: The redesigned nose pocket allows easier equalization. Increased spacing between the nose and frame makes it easier to pinch, even when wearing thicker gloves.

Comfort & Fit Engineering

Curled Lip Skirt with Integrated Strap Clip: Ensures firm but gentle contact with the face, reduces pressure marks, and provides a reliable seal when tightening the strap.

DX Spec Mask Buckle: Features a fine pitch strap adjustment system for easy one-hand operation, fully functional even with thick gloves.

Soft Damper Technology: Masks designed for improved downward vision often increase cheekbone pressure. This technology reduces stress on cheekbones, improves comfort during long dives, and maintains effective sealing.

Drain Skirt System: Enhances water expulsion during mask clearing and minimizes water pooling inside the mask.

Low Volume Advantage

With a low internal volume of 110cc, the lens sits closer to the eyes, providing a wider field of vision, easier mask clearing, and greater underwater efficiency.

High-Performance Lens Technology

UV420 CUT AR Amber Lens: Provides protection against UV rays up to 400nm and HEV light (400–420nm). These light ranges contribute to oxidative stress and the deterioration of lutein, which protects eye tissues. The benefits include reduced oxidative stress, protected lutein, and enhanced long-term eye comfort.

Amber Lens Visual Advantage: The amber tint increases contrast, improving visibility and making objects easier to distinguish underwater by sharpening edges and defining shapes in variable light conditions.

Anti-Reflection (AR) Coating: While standard lenses offer ~92% light transmission, UV420 AR lenses provide ~95%. This results in reduced glare and reflection, brighter and clearer vision, and a more natural visual experience. Anti-reflection also improves underwater communication by making eye contact easier.
