This suit uses Metalite-coated neoprene to “reflect” warmth back to the body and increase heat retention, while shedding water quickly to help protect against wind chill when you’re back on shore.

ScubaLab reviews the Tilos Men’s 3/2 mm Delphite SuperStretch Jumpsuit

Tilos’ one-piece vest uses MetaLite, a smooth reflective coating on the inside of the neoprene that reflects body heat while you’re cruising the reef and sheds water quickly to help protect against wind chill when you’re back on the boat. The 3mm torso is comparable to a 4- to 5-mm in warmth. And the vest is easy to take off — MetaLite’s smooth texture with 4-way stretch and side zipper makes donning and doffing a breeze. Available in men’s sizes from Small to 2 Extra-Large and women's Small to Extra-Large.

BARE ELASTEK suits offer legendary, anatomically correct patterning, for a 3-D shape that delivers industry leading comfort and fit. These highly versatile suits can be complimented with ELASTEK accessories, including hoods, gloves and boots, that will have you covered from head to toe.
