SeaDek had over 20 years of experience in this space (EVA/PE) and knows through testing what materials and adhesives work best in the marine environment. Rigorous laboratory testing is ongoing all the time and they are always looking at lamination, laser cutting, design and colors to stay ahead of the marketplace.
Looking cool is part of the benefits but its cushioning and traction is great on the legs and back, too. I have noticed that my knees and back that had given me fits in my carpeted boats after a long day on the water is gone now. My old bones thank me every trip that I have fished on top of SeaDek.
