When we think of rain jackets, many of us think of something that keeps us dry in a downpour. However, staying dry is more than just blocking the rain. It is also about managing sweat and moisture from the inside. This is where breathability matters to your rain jacket. A breathable rain jacket isn't just waterproof but allows your body heat and sweat to move through the fabric too. This can make all of the difference when you are active outdoors.
The Science Behind Breathable Rain Jackets
Breathable rain jackets use a membrane or coating used in the fabric itself. This membrane has microscopic pores that are small enough to keep water droplets (like rain) from getting in, but large enough to allow water vapor (sweat) to escape.
One of the most used materials for breathable jackets is GORE-TEX® but there are many others, like eVent, HyVent, and DryVent. Each brand has slightly different technology, but they are all striving for the same result: water resistance and breathability.
Another important feature is ventilation. Many jackets have pit zips or back vents. These are extra openings you can unzip to let fresh air in. Overall, they will not only provide some airflow, but also help to cool your body temperature quickly while hiking, jogging, and cycling.
How Do You Measure Breathability?
In outdoor gear, the standard for breathability is MVTR or Moisture Vapor Transmission Rate. An MVTR number represents how many grams of water vapor can pass through a square meter of fabric in a 24-hour period. The higher number means better breathability. An MVTR of about 10,000 g/m²/24h is good enough for most people; but if you actively pursue sports or hiking, you may want something that is rated 20,000 or more.
Keep in mind that breathability is affected by humidity, wind, and perspiration. Different jackets feel breathable at different times. A jacket may feel breathable on a mild, dry day, but be less breathable when it is humid and warm outside. That’s why it is vital to pick the right jacket for your needs.
Why Breathability is Necessary?
If your rain jacket is not breathable, you will get wet from the inside out. Your sweat builds up, you overheat, and soon you become just as wet as if you had no jacket on at all. In outdoor activities like hiking, running, or biking, breathability is not just a bonus. It is essential for comfort and safety.
When buying rain jacket women will love, consider what it will be used for. If it is for light daily use, it may be sufficient to find a basic, water-resistant jacket. If your outdoor adventures are more intense, be sure to choose a fully waterproof, fully breathable jacket. Also, consider having features such as sealed seams, an adjustable hood, and multi-layering which balances weatherproofing with ventilation.
Where to Find Great Deals?
Breathable jackets can be expensive, but that doesn't mean you have to pay full price. You can often find great women's rain jacket sales online or at outdoor gear stores. Look for deals during off-seasons or special clearance sales. Just ensure you check the product specifications for breathability ratings and features.
Final Thoughts
A breathable rain jacket goes beyond being just a rain shield. It offers a way to stay dry and comfortable. From the technology behind waterproof membranes to some savvy shopping ideas, understanding how a rain jacket is breathable can help you get the right jacket that fits your situation. Whether you are walking to work or hiking up a mountain, the right gear can make the whole difference.
