About this item Made from Everflex Yulex plant-based foam for comfort, durability and sustainability. The Yulex Dive foam variety chosen by SCUBAPRO offers superb water compression resistance, providing years of use at all depths. Vest is assembled with blind-stitched seams using a solvent-free glue, a better process for people, the environment and the ocean. Pure Design Concept uses fewer seams and panels for maximum range of motion. Vest offers 5mm thermal protection in the torso area, front and back, with 3mm side panels for added flexibility. Inside of vest is lined with a combination of blue Diamond Span fleece and black stretch polyester, the latter of which is made from recycled plastic bottles. Hood provides a thickness of 3mm laminated with an outside/inside black polyester lining. Also features a 2mm face seal.
