Featuring our brand new FlexSkin technology, the Equation 4/3 FlexSkin FZ is an ultra-stretch and durable wetsuit for chilly water in spring and summer sessions! Our Equation wetsuits are made with Eicoprene which is a non-petroleum-based synthetic foam coming from a mix of limestone and recycled tires (30%). The lamination process to paste the recycled polyester lining uses Aqua-A™ water-based glue which is completely solvent-free and with no harmful chemicals. The Equation 4/3 Front Zip version is designed for your sessions in cooler water (52-63 °F). This wetsuit stands out thanks to its WPF lining (Warmth Performance) that is our warmest wetsuit lining. Built using a 3D-Knit construction, the WPF lining provides warmth by trapping air between each loop. The denser fabric provides extra comfort. Its front zip and watertight seals minimalize water entry. Comfort zones protect your ribs when paddling. It also features glued then blind-stitched Fully-taped seams (GBS) which gives protection, stretch and water resistance.
