Tilos' top-of-the-line Zenith 3/2 fullsuit is made of double-lined 250-percent Supreme Stretch neoprene 3 mil in the torso area, 2 mil in the arms and lower legs. Seams are quadruple-glued and blind-stiched, and a 9-mil spine pad cushions the tank and seals against a smoothskin strip to prevent water seepage.
The suit has a soft, supple feel, and the Supreme Stretch neoprene molds to your body like a second skin, offering unfettered range of motion. The sealing system is first rate, and the 360-degree smoothskin neck seal has an adjustable collar for a snug fit. The Glideskin wrist and ankle seals are the fold-under style with gusseted zip-over closures. This system creates a comfortable watertight seal when in the water, plus makes donning and doffing the suit much easier. The Thermowall body helps retain heat with its water-repellant material, and a pair of thick Tatex kneepads protect a lot of leg area, yet are so flexible they don't inhibit leg movement.
The bottom line: The feature-rich Zenith 3/2 suit is comfortable, and has an excellent sealing system to keep water out and warmth in. It's available in 11 sizes, including large-tall and extra large short.
