The Polygon Black freediving suit jacket is made of 5mm thick open cell neoprene in black/indigo. The polygon-based indigo camouflage design makes a spearfisher’s profile "invisible". A preformed cut ensures comfort and an excellent fit with a non-slip chest pad which includes an internal neoprene "shock absorber". The chin shape adapts to faces even better than before, and a VELCRO® Brand beavertail closure allows for perfect adjustment.
