"Water-repellent" and "waterproof" are terms you often see when choosing outdoor wear. While both relate to water, they do not mean the same thing.
Whether you want to wear it for walking around town on a light rainy day or need to prepare for continuous rain, understanding the differences based on your intended use will make it easier to choose the right gear.
What is water-repellent? Repelling water droplets on the fabric surface
Water-repellent refers to a property where the fabric surface repels water droplets, preventing water from spreading. On fabric treated with a water-repellent finish, you can often see water droplets bead up and roll off.
This is useful for light rain or protection against splashes, but water-repellent treatment alone does not necessarily prevent water from penetrating. If it rains for a long time or if water pools on the surface, moisture may seep through the fabric or seams to the inside.
Do not assume it is "completely waterproof" just because it repels water; be sure to check the product specifications.
What is waterproof? Preventing water from entering
Waterproof refers to properties and construction designed to keep water from getting inside. For apparel, this often involves using fabrics with waterproof membranes or coatings.
However, using waterproof material is not the same as the garment being entirely waterproof.
Even if the fabric itself has waterproof performance, water can still enter through seams, zippers, or openings. When choosing gear for rain, it is important to check not just the fabric, but the entire construction of the garment.
The difference between water-repellent and waterproof
| Comparison points | Water-repellent | Waterproof |
|---|---|---|
| Main role | Repels water droplets on the fabric surface | Prevents water from entering |
| What to check | Presence of finish and the affected areas | Fabric, as well as seam and opening specifications |
| When to choose | Protection against light rain or splashes | Preparation for potential continuous rain |
| Points to note | Even if it repels water, it may still enter | The level of protection varies by usage conditions and garment construction |
A garment may not necessarily feature only one or the other. Some garments made with waterproof materials may also have a water-repellent finish on the outer fabric.
When water-repellent gear is suitable
Water-repellent treated gear is a good option for walking around town on days with stable weather or for protection against minor splashes.
You can find water-repellent finishes on not only jackets but also pants and hats. Choose something that fits your needs by considering comfort, ease of movement, and breathability.
Note, however, that water-repellent clothing does not necessarily serve as a substitute for rain gear. If rain is in the forecast or if you are in an area where the weather changes quickly, be sure to have separate rain protection.
When to consider waterproof gear
If you plan to walk in the rain or there is a possibility of continuous rain during your activity, consider gear that has been verified for waterproof specifications.
When choosing, use the following points as a guide:
・Does the fabric have waterproof performance?
・Are the seams treated for waterproofing?
・What is the construction around the zippers?
・Can the hood, cuffs, and hem be adjusted?
・Does the product match the intended use?
Proper adjustment while wearing is also important to suppress water entry. If there are large gaps in the hood or cuffs, water may enter through those areas.
"Waterproof-breathable" does not always mean it won't get stuffy
Waterproof-breathable materials are designed to keep water out while allowing moisture vapor from inside the clothing to escape.
However, comfort while wearing is not determined solely by the material's performance. It also changes depending on temperature, humidity, physical activity levels, and base layers.
Check for features like ventilation zippers and consider your layering combination so that you can easily regulate your temperature when you get hot from walking.
Watch for scope of treatment and differences by color
Depending on the product, the water-repellent finish may only be applied to the main body or specific areas. Furthermore, the same product may vary in its treatment depending on the color.
Don't just look for the term "water-repellent"; check the product notes to see which parts or colors are covered.
Follow product care instructions
Water repellency can be affected by friction and dirt from everyday wear. When caring for your gear, always check the laundry symbols and product guide first.
The use of detergents, fabric softeners, drying methods, and re-waterproofing agents varies by product. It is important to avoid a one-size-fits-all approach and care for the item according to its specific requirements.
Choose based on the weather
Use water-repellent gear for protection against light rain or splashes. For scenarios where there is a risk of continuous rain, your options should include gear with verified waterproof specifications.
Do not judge by the name alone; check the fabric, seams, openings, and coverage of the finish to choose the gear that fits the weather and your activities.
