Do Rain Jackets Lose Waterproof?.
Waterproof Your Waterproofs: Debunking the Myth of Rain Jacket Durability
A Tale of Two Coatings: DWR and Membranes
When it comes to keeping us dry in the face of Mother Nature's showers and downpours, rain jackets are our trusty companions. However, have you ever noticed that your once-waterproof jacket seems to be losing its effectiveness over time? Does water start to bead up instead of rolling off, or does the fabric feel less breathable? These are signs that your rain jacket's waterproofness may be waning.
The reason behind this decline in waterproofing lies in the two key components that make up a modern rain jacket: durable water repellent (DWR) and a waterproof membrane. The DWR, a hydrophobic coating applied to the outer fabric, acts as a repellant, allowing water droplets to bead up and roll off rather than soaking into the material. This delicate coating, however, is susceptible to wear and tear, especially from abrasion, UV rays, and harsh chemicals.
The waterproof membrane, typically made of a material like Gore-Tex or eVent, is the true barrier that prevents water from penetrating the jacket's interior. These membranes are extremely fine, allowing moisture vapor from your body to escape while keeping out larger water molecules. However, even these membranes can be compromised over time due to repeated washing, exposure to chemicals, or extreme temperatures.
Restoring Your Rain Jacket's Waterproof Edge
While the lifespan of your rain jacket's waterproofing can vary depending on usage and care, there are steps you can take to extend its effectiveness. Regular washing and drying using a gentle cycle and low heat will help preserve the DWR coating. For more stubborn stains, use a mild detergent specifically designed for outdoor gear.
If you notice your jacket's DWR starting to lose its grip, reapplication is essential. There are various DWR reproofing treatments available, such as those offered by Nikwax, Grangers, and ReviveX. These treatments work by rewetting the DWR coating, restoring its hydrophobic properties and making water droplets bead up again.
Prolonging the Life of Your Rain Jacket
Beyond regular washing and DWR reproofing, there are other preventative measures you can take to prolong the life of your rain jacket:
-
Avoid Excessive Folding: Folding your jacket repeatedly can strain the seams and reduce its overall durability. Instead, hang your jacket to dry or store it flat when not in use.
-
Avoid Harsh Chemicals: Keep your rain jacket away from harsh chemicals like insect repellents, sunscreen, or gasoline. These substances can break down the DWR coating and membrane, making your jacket less effective.
-
Handle with Care: Avoid dragging your rain jacket over rough surfaces or bushes, as this can damage the fabric and compromise its waterproofing.
-
Repair Minor Tears Promptly: Small tears or snags can quickly turn into larger problems. Repair them promptly using a quality seam sealant or fabric tape to prevent further damage and potential water intrusion.
By following these tips and maintaining proper care, you can ensure that your rain jacket continues to provide reliable protection from the elements for years to come. Remember, a well-cared-for rain jacket is an investment in your comfort and safety, whether you're hiking, camping, or simply commuting on a rainy day.
