Cressi's Summer 2.5mm Nylon II neoprene Jumpsuit is a great warm water suit. TheSummer has a rear YKK zipper, with an Aqua-Stop flap under the zipper and a skin-in neck seal for added warmth. Metallite cuffs at wrists and ankles make it easier to put on and take off.
The legs are anatomically preformed to give a natural feel and an easier kicking movement. High-Stretch Ultra-span neoprene at the shoulders and under the arms increases the freedom of movement. The Summer is one great suit for warm water diving.
