Reality Check: Is Leather Waterproof?

Summary

• Leather is not naturally waterproof and can be damaged by prolonged exposure to water—leading to stiffness, loss of shape, mold, and mildew.
• Different types of leather have varying degrees of water resistance, with full-grain leather being more resistant than suede or nubuck.
• Waterproofing treatments for leather are not permanent and require regular reapplication to maintain protection.
• Marine-grade vinyl is a better alternative for motorcycle seat covers due to its superior weather resistance and lower maintenance requirements.

Leather is used to make riding gear, accent saddlebags, and of course, cover motorcycle seats—but while popular, it may not be the most ideal material for the job. That’s because leather isn’t waterproof, and even conditioning it won’t fully prevent water from damaging it over time.

We use marine-grade vinyl in our motorcycle seat covers instead of leather so that we can give riders superior weather resistance. Below, our team explains why leather isn’t waterproof and what you can do to take better care of the seat you count on for comfort during your two-wheeled adventures.

3 Myths Debunked About Leather's Water Resistance

Myth: Leather is Naturally Waterproof

Reality: Leather can be damaged by enough exposure to water.

While leather can resist some water, prolonged exposure or heavy soaking can damage the material, causing it to stiffen, lose its shape, or develop mold and mildew.

When water comes into contact with leather, it binds to the oils inside the material and draws it out. Over time, this leads to the leather becoming brittle and stiff, which impacts comfort and makes cracking more likely.

Myth: All Types of Leather are Equally Water-Resistant

Reality: Different types of leather have varying degrees of water resistance.

Full-grain leather is more water-resistant due to its dense fiber structure, whereas suede and nubuck are more susceptible to water damage. Suede waterproofing spray can help, but it also runs the risk of affecting the way the suede looks and feels.

Myth: Once Treated, Leather Remains Waterproof Forever

Reality: Waterproofing treatments can help protect leather, but they are not permanent.

Regular reapplication of waterproofing products is necessary to maintain protection. The intervals at which you should reapply depend on the quality of the leather, how often it’s exposed to the elements, and the severity of each exposure. This means leather riding gear and accessories actually require careful monitoring and maintenance to keep them in good shape.

Why Leather Motorcycle Gear Needs Treatment & Care

Leather motorcycle gear and bike accessories require proper care to maintain their functionality and appearance. Here’s why:

• Properly treated leather can offer better protection against rain, wind, and debris. Untreated leather can absorb water, which weakens the material and reduces its effectiveness.
• Regular care, including cleaning and conditioning, helps prevent cracks, drying, and other forms of wear and tear.
• Well-maintained leather retains its strength and integrity, which helps protect you and certain parts of your bike in case of an accident.

How to Maintain & Waterproof Your Motorcycle Leathers

Regular Cleaning

• Use a damp cloth to wipe away dirt and dust.
• For deeper cleaning, use a leather cleaner or mild soap solution.
• Avoid harsh chemicals that can damage the leather.

Conditioning

• Apply a leather conditioner when you notice the leather starting to dry or fade.
• Use products specifically designed for leather to avoid damage.

Waterproofing

• Use a waterproofing spray or wax designed for leather.
• Products with beeswax or silicone are popular choices.
• Test the product on a small, inconspicuous area first.
• This helps you make sure the product won’t discolor the leather.
• Apply the waterproofing treatment evenly, following the manufacturer’s instructions.
• Reapply as needed, especially before exposure to wet conditions.

Storage

• Store leather items in a cool, dry place.
• Keep gear away from direct sunlight and heat sources to prevent fading and drying out.
• Use breathable garment bags to protect from dust while allowing air circulation.

Handling Wet Leather

• If the leather gets wet, blot (don’t rub) the excess water with a soft cloth.
• Allow the item to air dry naturally.
• Keep it away from direct heat sources like radiators or hair dryers
• Too much heat can cause the leather to become brittle.
• Once dry, apply the conditioner to restore moisture lost during the drying process.

Luimoto’s Alternatives to Leather Seat Covers

Instead of leather, our rider and passenger seat covers use high-quality marine-grade vinyl. Here’s why:

• Better water resistance—this type of vinyl is the same material used to protect equipment and metal surfaces on commercial fishing vessels.
• Japanese synthetic suede can be used to upgrade the appearance of panels without being as delicate as genuine suede.
• Requires less maintenance over time. To protect your Luimoto seat cover when not riding, simply apply one of our weather protectors made with PU waterproof coating.

We make seat covers for a huge range of different bikes, and also create custom one-of-one covers with unique stitching, embroidery, and material upgrades. Explore our made-to-order collection below or start your custom order here.

Frequently Asked Questions about Leather for Motorcycle Gear

What are the signs that my leather gear needs conditioning or waterproofing?

Signs that your leather gear needs conditioning include a dry or faded appearance, stiffness, or small cracks. If water no longer beads up on the surface, it’s also an indication that waterproofing needs to be reapplied.

Can I use household products to clean and condition leather?

It is not recommended to use household products like vinegar or olive oil on leather, as they can damage the material over time. It’s best to use products specifically designed for leather care to ensure proper cleaning and conditioning without causing harm.

How should I store my leather gear to maximize its lifespan?

Store your leather gear in a cool, dry place away from direct sunlight and heat sources. Use breathable garment bags to protect from dust while allowing air circulation. Avoid plastic bags that can trap moisture and lead to mold growth.

Is synthetic suede better than genuine suede for motorcycle gear?

Synthetic suede can be a good alternative as it is less delicate and offers better durability while maintaining a similar appearance and texture. It is also easier to maintain and can provide superior protection against the elements when used in motorcycle gear.
