Running jacket

Running is a sport that can be practiced regardless of the weather, as long as you are prepared. A running jacket is one of the key pieces of equipment for every runner. However, choosing the right one may not be easy. In this article, we will discuss what to consider when buying a jacket, including waterproofing, windproofing, weight, adjustability and additional features such as pockets and reflectors.

In this guide, we break things down to their most basic components. We show you what’s important and what’s not.

1. Waterproofing and Wind Protection 

In changeable conditions, waterproofing and windproofing are key features of a running jacket.

Both jackets without membranes and models equipped with windproof and waterproof membranes are available on the market. Jackets without membranes protect the body from cooling down due to cold air, especially in open terrain. These jackets are usually cheaper.

Conversely, jackets with membranes, such as GORE-TEX, offer effective protection against rain, making them a more expensive but versatile option. These membranes have high waterproofing parameters (e.g., 10,000–20,000mm water column) while allowing air to escape. Therefore, jackets with membranes provide adequate waterproofing and windproofing, guaranteeing comfort and protection regardless of the weather and allowing you to focus on your training.

2. Lightweight and Packable Design

A running jacket should be made of lightweight, advanced materials that allow for maximum freedom of movement and comfort during activity. Lightweight fabrics make the jacket nearly imperceptible on the body. Additionally, the jacket’s low weight often makes it easy to store — many models can be folded down to a small size and tucked away in a pocket.

Therefore, when choosing a jacket, it is worth checking if it has a dedicated pocket for easy folding and storage. This practical feature is useful for both urban runners and those who train over longer distances in the countryside.

3. Fit Matters: Choosing the Right Cut

A running jacket’s fit is crucial for ensuring comfort and freedom of movement during training. An ergonomic design, created with runners in mind, allows the body to move naturally without restriction. Additionally, elastic panels or inserts in strategic areas, such as the shoulders and sides, provide a better fit. Another important feature is the jacket’s extended back, which effectively protects the lower back from the cold and moisture. Thanks to these features, the jacket is comfortable and practical, allowing you to focus fully on your workout.

4. Adjustability for a Better Fit

In addition to fit, adjustability is also important. Drawstrings at the bottom of the jacket allow you to adjust its circumference. This prevents wind from blowing in and helps keep you warm. An adjustable hood protects your head from rain and wind, and it won’t fall off while you’re running. Additionally, adjustable cuffs provide a snug fit around the wrists, helping to retain heat and protect against cold air. These features make the running jacket more comfortable and functional.

5. Pockets – Preferably Waterproof

Pockets on a running jacket are an extremely practical feature that increase its functionality. Closable pockets allow you to safely store small items. The waterproof finish of the pockets is particularly important because it protects the contents from moisture on rainy days and ensures the safety of electronic devices.

However, remember that if you carry more small items for training, a jacket pocket may not be practical. The movement of objects can be distracting and irritating. Therefore, if you often carry your keys, phone and energy gels, a hip belt that can hold all these items is a better solution. It will also fit your body much better.

6. Reflective Elements for Safety

Reflective elements on a running jacket are crucial for safety, especially when training in conditions of limited visibility, such as fog or rain, or at dawn or dusk. These elements reflect light, making the runner more visible to drivers and other road users. This inconspicuous yet essential feature significantly reduces the risk of accidents and allows you to feel more confident when running in urban areas or on dimly lit routes.

Remember, a running jacket should be adapted to weather conditions and the runner’s individual needs. Testing different models is worth it to find the perfect balance between protection, comfort and functionality.
