For anyone who treats their underwater gear with the respect of a professional, this is the clear, logical selection.

How to Properly Apply Spray to Your Drysuit Seals

Consistency is more important than volume when applying protective spray to your seals. Begin by ensuring the seals are clean and completely dry; applying spray over salt or dirt will only trap those abrasive particles against the rubber. Use a soft, lint-free cloth to gently wipe the seals down with fresh water first, allowing them to air dry in the shade.

Once clean, spray a small amount of the product onto a clean microfiber cloth rather than directly onto the seal. This prevents overspray from getting onto the delicate fabric of the drysuit, which could affect its breathability or waterproof membrane. Gently wipe the cloth around both the inside and outside of the neck and wrist seals to ensure an even, thin coat.

Allow the seals to sit for at least ten minutes to absorb the protectant before packing the suit away. If the seals feel greasy or tacky to the touch, you have applied too much; use a clean, dry cloth to buff off the excess. Always store the suit loosely rolled or hung in a cool, dark place once the seals have been treated.

Understanding UV and Ozone Damage on Rubber Seals

UV radiation is the primary enemy of rubber seals, working silently to break down the polymer chains that give them their flexibility. When seals are exposed to direct sunlight during transport or while waiting at the launch point, they undergo a process called photo-oxidation. This manifests as micro-cracking and a loss of elasticity, which eventually results in catastrophic tearing.

Ozone damage is a more subtle threat, often occurring when gear is stored near electric motors, fluorescent lights, or in poorly ventilated garages. Ozone acts as a powerful oxidizing agent that attacks the double bonds in the rubber, leading to what is commonly referred to as “dry rot.” Once a seal begins to show signs of ozone degradation—usually a brownish, brittle appearance—the damage is irreversible.

Mitigating these threats requires a dual-pronged approach: consistent application of UV-blocking protectants and mindful storage. Keeping your drysuit inside a dedicated bag when not in use is a simple, highly effective way to block both harmful light and ozone exposure. A few seconds of preventative care significantly delays the inevitable decay that sunlight and air bring to your equipment.

Best Practices for Long-Term Drysuit Gear Storage

The most dangerous time for your drysuit is when it is sitting in your gear closet between seasons. Never store a drysuit tightly folded, as this creates permanent creases in the latex that act as stress concentration points for future tears. Instead, hang the suit on a wide, sturdy hanger designed for heavy gear, ensuring the seals aren’t stretched or compressed by neighboring equipment.

Temperature and humidity control are equally critical for long-term survival. Aim for a cool, dry environment away from direct sunlight, such as a closet or a climate-controlled basement. Avoid storing your suit in an attic or a shed where seasonal temperature swings can bake the rubber and cause it to lose its structural integrity over time.

Finally, place a silica gel packet inside the suit or near the seals if the storage area is prone to dampness. This keeps the environment dry and further protects the delicate latex and zipper components from mold and mildew. By treating the storage phase with as much care as the trip itself, you ensure your gear is ready the moment the season begins.

How to Know When It Is Time to Replace Your Seals

Even with the best maintenance, latex seals have a finite lifespan and will eventually degrade. You should inspect your seals before every trip by gently stretching the latex and looking for small, jagged cracks along the edge. If you see any white or gray lines—signs of oxidation—it is an early warning that failure is approaching.

A simple stress test involves checking for “tackiness” or permanent deformation. If the seal does not snap back to its original shape immediately after being stretched, the latex has lost its elasticity and will no longer provide a watertight seal. Never attempt to “patch” a cracked seal with adhesive or tape; this is a temporary fix that will inevitably fail in the middle of a trip.

If you find yourself questioning the integrity of your seals, replace them immediately. A failed seal in cold water is a significant safety risk that can turn a fun day into a life-threatening emergency. Err on the side of caution and view replacing your seals as a standard, periodic maintenance task rather than a reactive repair.

Taking a few minutes to protect your drysuit seals pays dividends in both equipment longevity and personal comfort on the water. While no product can stop the natural aging process entirely, the right protectant significantly slows the decay caused by sun, salt, and storage. Choose a product that fits your adventure style, keep those seals clean, and you will find your drysuit remains a reliable, watertight partner for many seasons to come.
