The Mares Kona dive mask is extremely lightweight and compact but without compromise on quality.
Low volume and soft silicone makes this mask easy to clear and extremely comfortable. The simple and compact buckles mounted on the skirt make it fast and easy to adjust the strap. For an easy approach to water activities- diving & snorkelling- it's a very good buddy in an economical mask.
