Designed to keep you warm while you are on/under the water for 1.5 to 3 hours, the product consists of a traditional short sleeve lycra modified to accommodate Thermalution’s waterproof battery system with non-metallic Heating Wire Technology and temperature controller.
My first impression after opening the box was that they looked kind of goofy as they look like a combination of sunglasses and goggles. Once I adjusted the headband to fit my extra large head I was blown away with the colors of the water. The Spex I tested came with polarized gray (smoke) lenses. The frame fit my face nicely and was very comfortable, but they might be too big for smaller faces and children.
