Cressi’s Lido two-mil shorty provides enough high-stretch neoprene to help keep you warm and protect against stinging critters, but not so much neoprene that you feel overdressed in the bathtub-warm waters of the tropics.

Designed for cold-water divers, Thermalution’s Power-Heated Undersuit can be worn beneath any wetsuit. A thin, flexible heating element built into the nylon/lycra Undersuit lays against your back and radiates heat while you’re cruising the cold depths.

Features: 3.5 mm Ultraspan highflex neoprene; glued and blind-stitched seams; smoothskin seals at wrists and ankles; smoothskin spinal flap; adjustable collar with smoothskin sealing surface; embossed rubber kneepads.

Features - 3 mm neoprene with high-stretch nylon- and polyester-based exterior and interior laminate; glued and blindstitched seams with full interior taping; glideskin neoprene seals on wrist and ankles; olled-edge smoothskin neck; full-length back zipper; pull-over secondary glideskin neck seal; high-fl ex embossed rubber patterning on knees, shoulders and waist; 1.5 mm Hydrolock neck dam.

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.
