Yamamoto Neoprene Care and Maintenance: A Kuhane Guide
Yamamoto neoprene is the most advanced material on the market — but it requires specific care. Unlike conventional neoprene, its nitrogen-filled closed-cell structure responds differently to external agents. Here’s everything you need to know.
Why Yamamoto care is different
Yamamoto #40 has 93% independent cell structure. That makes it more flexible, lighter, and more waterproof — but also more sensitive to aggressive chemicals, excessive heat, and mechanical torsion. Conventional neoprene can withstand more abuse; Yamamoto rewards careful handling with a longer lifespan.
After each session: the rinse
Sea salt degrades neoprene and sealants in the long term. The correct protocol:
- Rinse the suit with cold or lukewarm fresh water (never hot) for at least 2 minutes.
- Pay attention to the seams, zipper, and hood.
- Turn the suit inside out and rinse the interior as well.
- Never use hot water — it destroys the liquid sealant.
How to dry your suit correctly
Incorrect drying is the number one cause of premature deterioration:
- Always dry in the shade. UV sunlight degrades neoprene in just a few sessions.
- Hang the suit by the waist, not by the shoulders (avoid deforming the straps).
- Let the inside dry first — turn the suit halfway through the process.
- Never use a dryer or heater.
How to store it without damaging it
Between seasons or periods without surfing:
- Store the suit hung on a wide hanger, not folded.
- Avoid repeatedly folding the neoprene in the same area — it creates internal cracks.
- Store away from heat sources, direct light, and chemicals.
- A special hanger for wetsuits is the best secondary investment.
What damages Yamamoto neoprene
- Hot water and direct sunlight.
- Non-neoprene specific detergents or soaps.
- Contact with oils (sunscreens, gasoline).
- Repeated folding in the same area.
- Long fingernails and direct velcro contact.
Basic repairs
Small tears in seams can be repaired with neoprene cement or specific wetsuit glue. Apply to both surfaces, let dry for 2 minutes, and firmly press together. For larger tears, consult a specialized workshop.
Frequently asked questions
How often should I wash my suit with soap? Every 5-10 sessions with neutral shampoo or specific wetsuit soap. A fresh water rinse is sufficient for daily use.
Can I leave the suit wet in my backpack? No more than 2-3 hours. Sustained moisture creates mildew and degrades the interior jersey.
How many seasons does a well-cared-for Yamamoto suit last? Between 4 and 6 seasons with regular use and proper care.
