For running in winter, choose your jacket based on weather conditions and effort intensity. In cool, dry, and windy weather, a lightweight windbreaker may be enough. When the cold becomes more intense, an insulating and breathable jacket provides more comfort. In the rain, a waterproof jacket protects from both water and wind.
Temperature gives a first guideline, but it doesn’t tell the whole story. Wind, humidity, precipitation, duration of the run, and intensity can completely change your needs.
Here’s how to choose between a windbreaker, thermal jacket, and waterproof jacket to keep running comfortably during winter.
What type of jacket to choose for running in winter?
A dynamic run at 5°C without wind and a long run under 8°C with rain don’t require the same protection. To make the right choice, start by identifying what is really likely to cool you down: wind, rain, low temperature, or a combination of these factors.
| Conditions | Type of jacket | Main need |
|---|---|---|
| Cool, dry, and windy weather | Windbreaker | Block wind while maintaining good breathability |
| Dry cold | Breathable thermal jacket | Retain more heat during effort |
| Cold + rain | Breathable waterproof jacket | Protect simultaneously from water and wind |
| Variable weather | Modular jacket | Quickly adjust your level of protection |
Dry cold and wind: prioritize breathability
Wind quickly increases the feeling of cold, especially on exposed sections or when your pace slows down. In these conditions, a windproof layer can bring a lot of comfort without adding significant insulation.
During an intense session, your body quickly produces heat. A jacket that is too insulating or too closed can then encourage moisture buildup inside. For moderate, dry cold, a lightweight jacket that blocks wind while remaining breathable is often the most versatile solution.
When the cold sets in: add breathable insulation
When the temperature drops further, wind protection can be complemented by an insulating material. The goal is to retain some of the heat produced by your body while allowing moisture to escape during effort.
A well-designed winter jacket can combine different materials depending on the areas: protection on exposed parts, insulation on the chest, and more breathable zones on the back or under the arms.
Cold and rain: the waterproof jacket takes over
As soon as rain becomes persistent, a breathable waterproof jacket becomes more suitable. Its membrane protects from water and also blocks wind very effectively, greatly improving thermal comfort.
However, a waterproof jacket does not provide thermal insulation by itself. Warmth mainly depends on the layers worn underneath and your activity level.
Which Raidlight jacket to choose for winter running?
Raidlight jackets cover various winter scenarios: light wind protection, insulation for cold, waterproof membranes, or more structured 3-layer protection.
2IN1 WINDPROOF: for wind and cool temperatures
Weighing just 100 g, the 2IN1 WINDPROOF prioritizes lightness and versatility. Its windproof and water-repellent fabric offers suitable protection for cool, dry days, especially when the wind intensifies the chill.
Its fully removable sleeves allow you to quickly transform it into a vest. They can then be packed into the collar or their dedicated pocket when the temperature rises or intensity increases.
A lightweight and versatile jacket for cool, windy, and relatively dry outings.
Best for sustained effort when you want to block the wind without adding much warmth.

2IN1 SORONA WINDPROOF: for running in the cold
The 2IN1 SORONA WINDPROOF is more geared towards cold winter conditions. It combines Sorona Aura insulation, a stretch Thermofleece fabric with a brushed interior, and 3D honeycomb mesh zones on the back, sides, and underarms.
This design provides warmth where it's needed while promoting ventilation during effort. The windproof sleeves are removable to turn the jacket into a vest as conditions change.
With its 280 g, thumbholes, and two front pockets, it directly meets the needs of a winter running or trail session.
A winter jacket combining insulation, wind protection, and breathable zones to keep you running when temperatures drop.
The model to choose if you want a true Raidlight running jacket for the cold.

ULTRALIGHT 3.0 MP+® and TOP EXTREME MP+®: for cold in the rain
When rain joins the cold, MP+® waterproof jackets take over. Their membrane blocks precipitation and wind while allowing some moisture produced during effort to escape.
175 g · 25K/50K membrane · gusset compatible with a pack up to 12L.
To prioritize lightness, compactness, and high breathability.
200 g in size M · MP+® 20K/20K membrane · compact construction suited for trail and ultra.
For waterproof 20K/20K protection with a lightweight design.
With its MP+® 3-layer construction, 20K/20K membrane, and 436 g weight, the ADVENTURE MP+® 3X offers more structured protection than ultra-light trail jackets.
Its adjustable hood, adjustable cuffs, adjustable hem, and two zippered pockets make it ideal for winter activities where exposure to wind, moisture, and snow is greater.
A great option for winter hiking, snowshoeing, or skiing with a suitable thermal layer underneath. The jacket protects against the elements but doesn’t include thermal insulation.

How to dress for running in winter?
The logic of three layers lets you easily adapt your outfit to the conditions. The first layer, worn against the skin, helps wick away moisture. The second provides warmth when the temperature demands it. The third protects against wind, rain, or snow.
You don’t always need to wear three layers. An intense session in dry weather might only require a technical shirt and a windbreaker, while a long run in cold and rain may call for an extra thermal layer under the waterproof jacket.
Before and after effort: avoid cooling down
Your needs change as soon as you slow down or stop. After a session, your body produces less heat while your clothes may still be damp. Quickly adding a comfortable layer helps maintain a pleasant temperature during cool-down.
The VO3 MAX outfit fits this versatility logic: warm-up, waiting before the start, recovery, or moderate effort in cool weather.
A comfortable outfit for before and after effort, designed to retain heat when intensity drops.
The jacket features a stretchy, soft fabric, a high collar, and two large zippered pockets. The pants add two pockets, long ankle-thigh openings, and a water-repellent fabric.

| Situation | Recommended model |
|---|---|
| Cool weather + wind | 2IN1 WINDPROOF |
| Dry cold / winter outing | 2IN1 SORONA WINDPROOF |
| Cold + rain | TOP EXTREME MP+® |

| Before / after effort | VO3 MAX jacket + pants |
Start by finding the right balance between wind protection, breathability, and insulation.
Switch to a waterproof membrane and adjust the layers underneath according to the temperature and your effort level.
In summary
To run in winter, first choose your jacket based on the conditions. The 2IN1 WINDPROOF suits cool, windy days, the 2IN1 SORONA WINDPROOF offers more insulation when the cold sets in, and the MP+® jackets take over in the rain.
The outside temperature remains a useful indicator, but wind, humidity, and the intensity of your effort directly affect how cold you feel. A modular outfit lets you adjust your protection more easily throughout your run.
