How to get ready for outdoor training in any weather?
Heat, cold, wind, and rain – the ever-changing conditions outdoor sports enthusiasts face can be challenging… but they don’t have to be! Whether you’re hiking in the mountains, trail running, or cycling, with the right preparation you can enjoy your training to the fullest – even in the most unpredictable weather.
In this article:
-
Three layers (base, thermal, and outer) allow the outfit to adapt to changing weather conditions and maintain optimal body temperature.
-
Fabrics such as 4F Dry, Merino, NeoDry membrane, PrimaLoft and DWR, among others, provide breathability, thermal insulation, rain protection and quick drying.
-
Outdoor clothing should be lightweight, easy to pack and flexible so as not to restrict movement; technologies such as 4F Skin and 4-Way Stretch support freedom during activity.
-
Trekking, cycling and running require other details, such as jackets with water repellent coating, shorts with gel padding and shirts with quick-drying fibers.
Short summary:
How do you prepare for an outdoor workout?
The key is layering, especially if you’re heading out for a long trek or a multi-hour bike ride. Using three independent layers that you can mix and match freely allows you to adapt to changing weather conditions while keeping your body at the right temperature.
-
Base layer: breathable and quick-drying, perfect for warm, dry days. This includes technical T-shirts and longsleeves, leggings, and shorts.
-
Thermal layer: warm, yet lightweight and packable – easy to fit in your backpack. Think quick-drying hiking or training sweatshirts and fleeces and thin, lightweight insulated jackets.
-
Outer (protective) layer: jackets with membranes or water-repellent coatings that shield you from wind and rain.
Remember that each layer can be worn on its own or combined, depending on the weather. On warm, sunny days, the base layer may be all you need. When it’s cooler but still dry, you can throw on the insulating layer. If it’s warm but rainy, go with the outer shell. And when the conditions get really tough, all three layers work together to keep you protected.
In 4F’s outdoor collections – whether you run, cycle, or hike – you’ll find all three types of layers designed to keep you comfortable in any weather. Plus, the pieces are color-coordinated, so you stay stylish on the trail too.
Outdoor sports technologies
One of the key features of training apparel – especially when it comes to outdoor sports – is technology. It's not just about enhancing performance and comfort, but also about keeping you safe. When you're far from home, up in the mountains, on a long trail run or a multi-hour bike ride, you can only rely on what you’re wearing and what’s in your backpack. So what technologies are worth having on your side?
4F Dry
This is a special fabric finish that speeds up the absorption of moisture from the skin’s surface. It allows your sportswear to dry faster, prevents your body from getting chilled, and keeps you feeling fresh and comfortable – even during high-intensity workouts. It’s a versatile solution for any type of training: running, cycling, or long-distance trekking.

Merino Wool
Merino wool naturally regulates temperature – keeping you warm when it’s cold and cool when it’s hot. It’s lightweight, soft, hypoallergenic, and gentle on the skin. Plus, it resists odors, keeping you comfortable and fresh even after a full day of intense activity.

NeoDry Membrane
This breathable waterproof membrane protects you from rain and wind while allowing moisture to escape from the inside. It keeps your gear dry and breathable, so you stay comfortable – even when you're caught in a sudden downpour on the trail.

DWR Coating, Taped Seams & Water-resistant Zippers
A durable water-repellent (DWR) coating slows down the absorption of moisture – rain beads up on the surface of the fabric and runs off easily. Water-resistant zippers and taped seams complement this by preventing moisture from seeping in through stitch lines and openings. It’s an ideal solution for unpredictable weather, keeping your outerwear dry for longer – even in rain or snow.
PrimaLoft
PrimaLoft is a synthetic insulation material that’s perfect for outdoor wear. It’s incredibly lightweight while offering excellent thermal insulation. It breathes well, dries quickly, and retains its insulating properties even when wet – making it especially useful in the mountains, where intense activity meets challenging, fast-changing weather conditions.

Comfort and functionality
Whether you're training at the gym or outdoors, comfort is key. Feeling good and having full freedom of movement allows you to train effectively and fully focus on your activity.
4F Skin
This finish allows garments to fit your body like a second skin. It provides total freedom of movement and maximum comfort during all kinds of outdoor activities. Products with 4F Skin technology feature flat seams or are completely seamless to minimize the risk of chafing.

4-WAY Stretch
An exceptionally elastic fabric that stretches in all directions, ensuring complete freedom of movement and maximum comfort during physical activity.
Functionality is also a core feature of sportswear. The layers you take with you on a hike or bike ride need to be ultra-lightweight and easy to pack. That way, they’re always on hand when you need them – and when the sun comes out and temperatures rise, you can simply fold them away in your backpack and forget you're even carrying them. In the 4F collection, you’ll find ultralight jackets and sweatshirts that can be packed into their hoods or into special dedicated pockets.
What to wear for a trek?
The mountains are a place that often puts your preparation to the test. That’s why it’s best to go for layers you can easily mix and match to adapt to changing weather conditions. Breathable, quick-drying T-shirts will be perfect for sunny days (Merino wool tees work great here); warm midlayers insulated with PrimaLoft will keep you comfortable in cooler temperatures; and lightweight outer layers with a water-repellent finish will protect you from rain and wind.
Pro tip: make sure everything is light and compact – so it’s always ready when you need it!
What to choose from the cycling collection?
Cycling often feels like riding through all four seasons – you might start in warm sunshine and finish in biting wind. That’s why your gear should keep up with the changes and let you focus on the ride, not the weather. One of the most important parts of a cycling outfit is a pair of padded shorts with a gel insert to cushion impact and reduce discomfort over the hundreds of kilometers you’ll cover during the season. For warm days, choose breathable jerseys; for cooler temperatures, go for technical longsleeves and midlayers. Also pay attention to smart details like cycling pockets on the back for drinks and energy gels, and reflective elements to help keep you safe.
What to focus on in the running collection?
Do you trail run? Then you already know that outdoor running – whether in the mountains, across fields or through forests – requires the right gear. The new 4F running collection is designed to make your runs enjoyable in any conditions. It features breathable apparel made from quick-drying 4F Dry fabrics for warm, sunny days, as well as lightweight running layers and jackets with water-repellent coatings that will protect you from wind and sudden showers.
