Limestone replaces the petrochemicals found in other neoprene. Minimal Water Retention: The closed-cell geometric structure of the #40 neoprene has minimal water retention (99.7% water impermeable), resulting in a wetsuit that's warmer (the cell structure has better heat retention, so a 3/2 can perform in water temperatures that you would normally need a 4/3) and lighter (less water absorption) and dries extremely fast.
The #40 neoprene is one of Yamamoto's most flexible, which ensures our Onsen wetsuits move as smoothly as you do and provide the highest level of restriction-free movement.
HIGHER MEMORY VALUE
Our Onsen wetsuits fit better and hold up longer than oil-based neoprene suits, thanks to #40's honeycomb structure.
Solvent-free lamination of the Yamamoto #40 neoprene liners eliminate harmful Volatile Organic Compounds (VOCs), and no toxic hydrophobic coatings or laminations mean that all of our wetsuits are C-Free materials (free of C8, C6 and C4).
Meticulously designed and engineered into all Ride Engine wetsuits, our fit and construction are all about keeping you warm and protected from the elements for restriction-free movement and longer on-water sessions.
