The Quiksilver Men's Monochrome 43 Wetsuit keeps your core warm while you session cool water swells come spring and fall. With a neoprene thickness of 43mm, the Monochrome performs in water temperatures ranging from 54 to 68F. Quiksilver's FN Lite neoprene and low profile Hydrolock seams give the suit a thin, lightweight feel to keep you mobile and your style fluid. Built in Ecto flex knee pads not only promote flexibility, but they also increase the overall durability of this otherwise lightweight suit. Seals at the neck, wrists, and ankles prevent heat robbing water from creeping through, so you won't be warming up on the beach when the best waves start to break.
