The Aquanaut freediving mask features a 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).
