Dressing for Autumn & Winter Trail Running

By Kenny Stocker

Stay warm and dry on the trails with our seasonal running gear guide. Find out how to layer for comfort and performance in colder months.

As the days become shorter and the weather turns colder and wetter, heading out for a run can present more challenges than usual. However, with the right clothing, you can not only stay warm but also have an enjoyable experience. In fact, winter trail running can be even more rewarding than running in fair weather.

If you want to zoom out 10,000 feet and find more about getting ready for winter trail running check out our guide How to Survive the Winter Running Season.

Here we are going to focus on our top clothing recommendations that help us continue to run through the winter months.

Winter trail running clothing

The best windproof for running in winter

The outer or shell layer can be windproof or both wind and waterproof. Windproof layers are more breathable than fully waterproof jackets, which can be preferable while running. The Arro jacket is a lightweight, comfortable, windproof smock suitable for running in winter when protection from wind is all that is required.

The best waterproof for running in winter

When rain is a concern, a proper waterproof layer becomes essential. The Gravitas, with its stormproof hood and 2.5 layer fabric, is the standout lightweight choice for a waterproof running jacket.

The Foundation: Base Layer

Selecting the right base layer is vital for staying warm and comfortable in cold and damp conditions. The base layer is especially important to get right as it directly interacts with your skin, playing a big part in your perception of comfort.

Synthetic base layers generally suit fast paced aerobic activity like trail running. Synthetics also dry quicker than merino wool. If a non-wool options is what you are after, the Koulin Trail Long Sleeve, featuring Polygiene anti-odour treatment, will fit the bill well.

Among the natural fibre alternatives, merino wool stands out as an excellent choice for lower intensity runs or extreme cold due to its warmth. Ethically produced merino wool base layers are not only cozy but also align with eco-friendly considerations.

So when the ice has stuck your car doors shut we recommended the Alpkit Kepler merino base layer. Merino offers impressive performance and aesthetics across various weather conditions and retains its insulation properties even when damp. If your trails take you into the fells or you are out all day that extra comfort is going to be important.

By mixing merino and recycled polyester fibres you retain some of the benefits of the merino, but also gain extra durability and improved wicking. Aztec is our merino blend baselayer and is also available in both short sleeve and long sleeve flavours. The extra durability could be important to you if you wear a running pack or are participating in more intense activity.

Hybrid Comfort: Insulation with Freedom

Hybrid insulation jackets combine zones of gridded fleece around the core leaving your under-arms and the side panels uninsulated. This lets you dump heat when working hard, without losing wind protection. For cold weather when you are working hard we recommend the Griffon gridded fleece. For cold and windy weather either layer up your Griffon with an Arro jacket or pull on the Morphosis which maintains breathability and mobility.

Lower Body Protection

When the temperature drops all but the hardiest runners turn to Koulin Trail tights, transitioning from 3/4 length to full-length running tights in extreme cold. Reflective logos and trim are nice safety details for the dark nights.

Battling the Elements: Running Gaiters and Socks

As trails become muddier, the Kantju running gaiters provide added protection. Lighter and less cumbersome than walking gaiters, these gaiters prevent debris from entering your trail running shoes.

Socks play a crucial role in keeping feet comfortable and preventing frostbite and blisters. Merino Repeat socks are perfect for chilly days. For wet terrain, Rana waterproof socks are recommended. Using a thin liner sock with anti-microbial properties enhances comfort and hygiene.

Essential Running Accessories: Hat and Gloves

A Kepler Liner Beanie provides initial warmth for winter runs. For moderate cold, a lightweight pocketable net gaiter, such as the Kepler Draught Excluder, offers ear protection without overheating the head. A cap, like the Koulin Cap, offers protection from rain and wind, while a light hat can be worn over it.

Running gloves are essential for colder runs. Kepler Liner Gloves and Specta Pullover Gloves are suitable options, with reflective elements for visibility and touchscreen compatibility for managing devices on the go.

Looking after your winter trail running clothing

Your running clothes take a lot of stick through the winter months. Wash regularly using a suitable tech wash to maintain breathability and water resistance performance.

Embrace the challenges of your winter trail running and enjoy the benefits of a well-chosen outfit.
