Made with quality materials, like limestone-based neoprene and specially developed linings with stretch zones in high-movement areas. The upper-body panels are internally reinforced with Dakine's flexible THERMO insulation and a wind-resistant smooth skin panel on the chest and back to prevent windchill in exposed areas. The seams are 3D stitched and critically taped for maximum security, and the tapered 5/4/3-millimeter thickness provides the ultimate warmth and flexibility where they matter the most. And lastly, the back-zip design allows for easy entry and exit so you won’t waste any energy wrestling with your suit.
