The SLX X Zip is a Lightweight springsuit featuring premium technologies including an easy on/off X-Zip front entry system, ThermoCarbon lining, and glued & blindstitched seams. One-piece top sleeve design for maximum flexibility. 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. Texture embossed rubber that provides excellent wind resistance; ideal for outer chest panels hoods, and other areas that would otherwise lose warmth quickly. 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. Smarter product design means minimizing seams to maximize stretch. Any seams used are always pre-bent and contoured for a truly engineered fit.
