Aquanaut Mask

€79,00 EUR
For all Fourth Elements orders! Your order is a request, until we could check the availability.


The 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.

The 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 moulded silicone strap which is interchangeable with a fourth element 100% recycled mask strap (sold separately).

Zero plastic packaging
We set out to reduce and remove all plastic waste from all our masks. Instead of packaging our masks in traditional hard plastic cases, we’ve opted for a zero plastic, low volume mask case.
