The Fourth Element Aquanaut freediving mask features a new design of silicone skirt which has been developed to fit as many face shapes as possible from a single design. This low volume freediving mask, whilst compact in size, offers a surprisingly wide field of view, making this not just great for freediving, but a very capable all-purpose mask. It is fitted with a molded silicone strap which is interchangeable with a fourth element 100% recycled mask strap (sold separately, see SKU: FRTMS). The silicone double feathered edge skirt and wide style mask strap combine for a perfect seal and comfort on the face. Mask has dual tempered glass lenses. Mask has low-profile quick adjust buckles. The Aquanaut Mask has a large easy to reach nose pocket for ear equalization even when wearing gloves. Zero Plastic Packaging: All Aquanaut masks come safe and snug in an OceanPositive Aquanaut Mask Case. Designed to completely eliminate unnecessary single use plastic used in traditional dive mask cases, these zero plastic cases fit perfectly in your fin foot pocket for easy storage.
Building your Aquanaut Mask couldn't be easier. Which lens is right for you? How we perceive the underwater world is largely determined by what we see, and the mask we use is therefore the most important piece of equipment for most, if not all, scuba divers. Diving in caves is a different experience from snorkeling in tropical seas. Likewise, diving in lower visibility, temperate waters is different from the near unlimited visibility of some blue water locations. The Fourth Element's lens system in the Aquanaut Dive Mask is designed to deliver an optimized experience for different conditions when diving, whether for underwater photographers looking to maximize the light transmission or wreck divers needing to enhance their perception of dimly lit surroundings. Your dive adventure is unique and taking in the wonders of underwater world requires a lens tailored specifically to your dive.
Clarity:
Maximizing the amount of transmitted light, without any tint from impurities in the glass, the Clarity is the ideal lens for night divers and photographers. The Clarity lens is manufactured with the highest level of purity to deliver maximum visual acuity during a dive.
Contrast:
Filtering out some of the mid-range wavelengths of light in the visible spectrum, the Contrast lens has a green appearance. The Contrast lens provides full UVA and UVB protection from harmful ultraviolet which can damage the retina. Ideal for temperate seas.
