Product Overview

C4 Carbon Plasma XL mask diving mask is a premium low-volume mask engineered specifically for freediving and spearfishing. It combines advanced hydrodynamic design, high-quality materials, and an optimized fit for larger face shapes, delivering both comfort and performance in demanding underwater conditions.

This mask features an extremely reduced internal volume, which allows easier equalization and improved efficiency during deep dives. At the same time, the lens geometry and reduced distance between eyes and lenses create a wide field of vision, giving you excellent awareness underwater.

XL version is approximately 10% larger than the standard Plasma model, making it ideal for divers with larger faces while still maintaining the low-volume performance that experienced freedivers expect.

Why Choose the C4 Carbon Plasma XL Mask

C4 Carbon Plasma XL mask diving mask stands out because it delivers low-volume performance without sacrificing comfort — something many masks fail to achieve.

The reduced internal volume means:

less air needed for equalization
better efficiency at depth
improved diving comfort

At the same time, the slightly larger XL fit solves a common issue for divers with bigger faces — ensuring a proper seal without pressure points.

Additionally, the frameless construction and soft silicone skirt allow the mask to adapt naturally to your face, minimizing leaks and increasing comfort even during long dives. The proximity of the lenses to the eyes enhances peripheral vision, which is crucial for spearfishing and underwater awareness.
