Years in the lab led us to the innovation and technology for our exclusive StretchFlight neoprene. And what it generates for the 3/2 Everyday Sessions Back Zip Wetsuit is the superior warmth and comfort you need, plus all the flexibility you could ever want. Bluesign® certified, this eco-friendly wetsuit also has a lightweight feel. So there’s no worry about feeling dragged down. And as for cold temps and water blockage, you’d better believe our R&D team dealt with it and has it dialed in with an infrared thermal lining that will transform your body heat into warm energy.
