StretchFlight & WarmFlight®
Extra warm 3d lining, full taping for watertight seams, external seal for added warmth, flexible and durable body-mapped neoprene. The WarmFlight Eco Infrared is the warmest thermo liner built with infrared technology that traps and reuses body heat from with the raised fabric surface, and keeps you surfing longer in colder water. Flexibility where you need it. durability where it counts. This neoprene is designed to give you the best of both worlds. A strechy liquid seal over the GBS seams prevents leaking without hindering flexibility. Quiksilver is more committed than ever to ensuring their wetsuits perform in the water but have low impact on the environment. Quiksilver wetsuits feature sustainable materials and processes. These suits are made better by using natural limestone neoprene to replace petrochemicals, water-based lamination and glues to eliminate the need for toxic solvents, and reycling scrap rubber tires and neoprene waste.

Light and warm
This is my second Quiksilver wetsuit and so far so good. It does run a bit smaller than my previous one though, I'm 6'0'' and almost 190 lbs and the size Large feels short on the arms and legs, but it's so stretchy that it doesn't really make a difference once wet. Also, for a 5/4/3, it feels super light and flexible. Totally recommend but make sure to get the right size.

Nice suit for the price
I have the previous version of this suit liked it but the sizing was on the small side.This new model is a whole new ballgame feels very plush and is twice as stretchy so easy on/off the zipper had me a little worried but is easy to get started. So far I am happy with it and the price makes it very attractive.
