Leather is naturally water resistant. It can handle minor water contact, like light rain. Leather is porous and will absorb water if left exposed to it for too long. It can lose its soft texture and become stiff after it has been wet. It can begin to degrade if it is left wet too long.

Why can't Leather be Fully Waterproofed?

Leather will never be waterproof 100%, even with the best treatments. This is especially true as leather ages. The porous nature of leather makes it susceptible to absorbing water. Untreated leather that is exposed to water over time can be damaged and lose its original feel and look. Proper care and treatment will extend the leather's lifespan and increase its water resistance.

Are Leather Jackets Waterproof?

Leather jackets are not naturally waterproof, but their water resistance can be improved with specific treatments.

1. Aviator Leather Jackets

Aviator leather jackets are made from sturdy leather designed to provide warmth and protection. While these jackets are made to handle the elements, the leather itself is not waterproof. For regular use in wet conditions, it's best to apply a waterproof spray to maintain the leather's quality and longevity.

2. Vintage Leather Jackets

Vintage leather jackets are typically made from full-grain or top-grain leather. These types of leather are not naturally waterproof and can absorb water, potentially leading to stains or weakening of the leather.

3. Leather Biker Jackets

Biker jackets are made to be solid and resistant to various elements. Although the leather is tough, it is not inherently waterproof. The leather can absorb water, which may lead to staining or warping.

4. Leather Blazers

Leather blazers have sleek and polished appearance, and are typically made from fine leather that is not waterproof. The leather in these blazers can absorb water, causing potential discoloration and damage. 

5. Leather Bomber Jackets

Bomber jackets, traditionally made from durable leather, have a tough exterior. While the leather used in bomber jackets is not naturally waterproof, it can withstand small amounts of water. However, to protect the leather from potential damage, it is recommended to apply a waterproofing spray.

How To Waterproof Leather?

The best method to waterproof leather depends on the type of leather you are working with. Here are a few common methods.

1. Spray Protectant

A waterproofing solution that can be sprayed on is the easiest way to protect leather. These sprays create an impermeable barrier on the leather surface.

2. Beeswax cream

Beeswax works well as a natural waterproofing agent, especially on leather. You can purchase beeswax products or create your own waterproofing product by mixing olive oil and beeswax.

DIY Beeswax Cream

Ingredients: 2 ounces beeswax, 1 cup extra virgin olive oil.

Instructions: Melt beeswax and olive oil in a double boiler. Let the mixture cool down and become stiff. Use a soft, clean cloth to apply the cream and buff it into the leather. Repeat this process to create a protective coating.

3. Wax application

Wax can be applied directly to leather, which will also create a barrier that is waterproof. After cleaning the leather, use a soft cloth to apply a small amount of wax. Let it dry naturally. After the leather has dried, use a buffed cloth to remove excess wax and provide a protective shine.

Advantages to Waterproofing Leather

• A waterproofing treatment creates a protective layer that prevents water from entering the leather. The leather's natural oils are preserved, which reduces the risk of cracking.
• Waterproofing is a great way to maintain leather's natural appearance and feel. It prevents water stains and marks.
• Waterproofed Leather is more resistant to damage from exposure to water.

The Consequences of Wet Leather

Leather exposed to water may lead to a number of undesirable results:

1. Changes to Texture

Leather can go from soft and supple, to hard and brittle when it becomes wet. Water binds to the oils in leather and when it evaporates, the oils are taken with it. This causes the leather to become dried out.

2. Staining

Water may cause unsightly watermarks or stains on leather. Salts from the tanning process may rise to the top of the leather when it gets wet. This can leave salt stains.

3. Odor and Decay

If leather is not dried properly, it may develop a musty smell and begin to degrade. In damp leather, mold and mildew may form. This is especially true if the leather is stored in an environment that's humid.

How to Fix Wet Leather?

Follow these steps if your leather item becomes wet:

1. Blot Excess water: Blot excess water immediately with a dry, clean cloth.
2. Air Dry: Let the leather air dry naturally. Avoid direct heat sources such as radiators and hair dryers, which may cause the leather leather to become stiff.
3. Condition: Apply leather conditioner while the leather is slightly damp to replace the lost oils. Allow the conditioner time to fully absorb before reusing the item.

Conclusion

Leather does not have a natural waterproofing property, but it is water resistant. You can increase its water resistance with proper care and treatment, but it will never be completely waterproof. Understanding the properties of different leather types will help you protect your leather products from water damage.
