When it comes to outdoor activities, having the right gear is crucial. Among all the essential equipment, an outdoor jacket stands out as a key piece. One of the most important features of an outdoor jacket is its breathability rating. As a supplier of outdoor jackets, I’ve had numerous discussions with customers about this topic. In this blog, I’ll delve into what the breathability rating of outdoor jackets means, why it matters, and how it impacts your outdoor experience. Outdoor Jackets

Understanding Breathability Rating
Breathability in outdoor jackets refers to the jacket’s ability to allow moisture vapor (sweat) to escape from the inside of the jacket to the outside while preventing water from entering. It is measured in grams per square meter per 24 hours (g/m²/24h). This measurement indicates how much moisture the jacket can transfer through its fabric in a day.
There are two main methods to measure breathability: the MVTR (Moisture Vapor Transmission Rate) and the RET (Resistance to Evaporative Heat Transfer). The MVTR method measures the amount of water vapor that passes through a fabric sample under specific conditions. A higher MVTR value means the fabric can transfer more moisture, indicating better breathability. For example, a jacket with an MVTR of 10,000 g/m²/24h can transfer 10,000 grams of moisture per square meter of fabric in 24 hours.
On the other hand, the RET method measures the resistance of the fabric to the transfer of moisture. A lower RET value indicates better breathability. For instance, a fabric with a RET of 5 m² Pa/W is more breathable than one with a RET of 10 m² Pa/W.
Why Breathability Matters
Breathability is of utmost importance for outdoor enthusiasts. When you engage in physical activities such as hiking, skiing, or running, your body sweats to regulate its temperature. If your jacket doesn’t have good breathability, the sweat will accumulate inside the jacket, making you feel wet and cold. This can lead to discomfort, fatigue, and even hypothermia in extreme conditions.
A breathable jacket allows the sweat to evaporate quickly, keeping your body dry and comfortable. It also helps to maintain a stable body temperature, which is essential for optimal performance during outdoor activities. Moreover, a breathable jacket can prevent the growth of bacteria and odor, as moisture is removed from the fabric.
Factors Affecting Breathability
Several factors can affect the breathability of an outdoor jacket. The first is the fabric used. Different fabrics have different breathability properties. For example, Gore-Tex is a well-known waterproof and breathable fabric. It has a microporous membrane that allows water vapor to pass through while preventing liquid water from entering. Other fabrics like nylon and polyester can also be treated to enhance their breathability.
The construction of the jacket also plays a role. Seams, zippers, and vents can all impact breathability. Sealed seams can prevent water from entering but may reduce breathability. Zippers and vents can be used to increase airflow and improve breathability when needed.
The fit of the jacket is another important factor. A tight-fitting jacket may restrict airflow and reduce breathability, while a loose-fitting jacket may allow more air to circulate but may also let in more wind and water.
Breathability Ratings in Different Outdoor Activities
The required breathability rating of an outdoor jacket depends on the type of outdoor activity you’re engaged in. For low-intensity activities such as casual walking or fishing, a jacket with a moderate breathability rating of around 5,000 – 8,000 g/m²/24h may be sufficient. These jackets are usually more affordable and offer a good balance between breathability and waterproofness.
For high-intensity activities such as mountaineering or skiing, a jacket with a high breathability rating of 10,000 g/m²/24h or more is recommended. These jackets are designed to handle heavy sweating and provide maximum comfort during strenuous activities.

Choosing the Right Outdoor Jacket

When choosing an outdoor jacket, it’s important to consider your specific needs and the type of outdoor activities you’ll be doing. Here are some tips to help you make the right choice:
- Determine your activity level: If you’re engaged in high-intensity activities, look for a jacket with a high breathability rating. For low-intensity activities, a moderate breathability rating may be sufficient.
- Consider the weather conditions: If you’ll be in wet or cold conditions, choose a jacket that is both waterproof and breathable. If you’ll be in warm and dry conditions, a jacket with a higher breathability rating may be more suitable.
- Check the fabric and construction: Look for jackets made from high-quality fabrics with good breathability properties. Pay attention to the seams, zippers, and vents to ensure they are designed to enhance breathability.
- Try on the jacket: Make sure the jacket fits well and allows for a full range of motion. A tight-fitting jacket may restrict airflow and reduce breathability, while a loose-fitting jacket may let in more wind and water.
