Sigalsub Minima Matte Black Silicone Mask for Freediving and Spearfishing

Reaching challenging depths requires meticulous air management. One of the main obstacles for freedivers and spearfishermen is the need to compensate for the mask's internal volume during the descent: every cubic centimeter of air exhaled through the nose to prevent the suction effect is oxygen taken away from the dive's duration. Furthermore, masks with bulky profiles increase hydrodynamic drag and can create reflections on the silicone surface that alert the most elusive prey.
