The Infiniti Comp delivers unparalleled flexibility thanks to a large, seamless front and back ''comp''(edition ready) panel for maximum core range of motion. Premium seams and materials; 100% UltraStretch neoprene. Front entry attached at the right shoulder to keep more water out; with a SmoothSkin hem seal, pull cord/barrel lock combo, and a snap lock to keep zipper pull in place. Overlapping inner front and back neck panels (underneath the zipper flap) stretch to allow extra wide, step-in-through-the-neck entry. Inner neoprene lining with performance and environmental benefits. A blend of bamboo charcoal fibers and recycled polyester fibers provides excellent heat retention and helps improve warmth. Comfortable, lightweight neoprene with softer foam and a tighter weave textile for less water absorption and better durability. Inner waterproof stretch Fusion taping fuses seams together; used primarily in the upper body where maximum flexibility is required. A glued & blindstitched seam using pressure to bond panels together for a highly durable yet still flexible seam; finished with inner taping for comfort; used primarily in the lower body. A fully sealed, maximum stretch seam construction that keeps water out. Neoprene panels are glued and pressed together, then blindstitched (needle doesn't fully penetrate neoprene, keeping water out). Can be finished with seam taping for added stretch, durability, and comfort. Large, seamless body panel maximizes core range of motion. Smarter product design means minimizing seams to maximize stretch. Any seams used are always pre-bent and contoured for a truly engineered fit.
