-
🧅 Layered clothing is essential – follow the “onion” principle: thermal underwear, an insulating layer, and an outer jacket allow you to regulate your temperature and protect you from the cold.
-
🔥 Thermal underwear is crucial – choose merino wool or modern synthetics that wick away moisture and prevent hypothermia.
-
🧥 The insulating layer retains heat – choose a fleece, light down jacket, or insulated sweatshirt depending on the intensity of the hike and weather conditions.
-
🌧 The outer layer protects you from the weather – a jacket and pants with a membrane will protect you from wind, snow, and rain, while ensuring breathability.
-
🧤 Accessories make a difference – a hat, neck warmer, gloves, and warm socks are essential for staying comfortable and safe on the winter trail.
A brief summary – how to dress for the mountains in winter?
Layered clothing - the layering principle
Winter conditions in the mountains can be really demanding and changeable, so proper clothing is fundamental for comfort and safety during any adventure. Therefore the principle of layering, that is putting on layers of clothing that allows you to effectively protect yourself from the cold, moisture and wind will work best - especially in mountainous conditions. Such a way gives you a chance to quickly regulate the temperature, so you can avoid hyper- or hypothermia.
-
The first layer is thermal underwear, which wicks moisture away, keeps the skin dry and prevents hypothermia.
-
The second layer provides insulation. Here, for example, a fleece jacket or thermal sweatshirt will work. Its job is to retain heat and maintain optimal body temperature.
-
Layer three is a membrane jacket that primarily protects against wind, snow and rain, but also breathes so you won't overheat while you're active.

Such an outfit will allow you to easily adjust to changing conditions and intensity of activity. You can quickly take off or put on another layer at any time so that you don't get cold, but also don't overheat your body. This is a practical and effective solution for any winter hike.
How to choose a good thermal underwear?
Choosing the right thermal underwear is key for a successful and safe winter trip to the mountains. Anything that requires your particular attention? Remember that the material must provide great moisture-wicking properties so that you don't feel cold even during intense exercise. That's why cotton underwear is off the limit as it absorbs sweat and quickly becomes cold, which can lead to hypothermia.
-
merino wool, which naturally insulates, provides breathability and does not absorb odours while remaining warm even when wet,
-
synthetic fabrics, such as polyester or polyamide, dry out quickly and effectively transport moisture to the outside,
-
blend of these fibres with elastane admixture, helping the underwear fit snugly without restricting movement.
The best materials are primarily:
Fabric’s weight is also important - for winter, choose pieces with a higher weight, such as 150-190 gsm, which will provide extra warmth. This will make thermal underwear your first layer of protection against cold and moisture.
-
Men's seamless thermal underwear (top) - red made of quick-drying polyamide with elastane admixture for a good fit with seamless construction. Denser fabric weave makes it a perfect choice for winter mountain excursions.
-
Women's seamless thermal underwear (top) - burgundy is the perfect fit that you will appreciate during your mountain adventures. The material fits your body like a second skin, giving you unrestricted movement. The seamless design eliminates chafing, and the quick-dry finish keeps you dry even during intense workouts. You'll also love this piece for its ventilation zones, which improve air circulation to keep you comfortable all day long.
-
Women's seamless thermal underwear with merino wool (bottom) - grey if you are wondering how to dress for a winter trip to the mountains, these leggings are an absolute must-have during such adventures. Merino wool guarantees natural temperature regulation while the 4FSkin technology ensures that the material fits the body perfectly. Merino wool makes the material much more gentle on the skin, which can make a big difference in winter conditions.
Are you looking for tried-and-true pieces? Here are some items worth your attention.
Insulating layer - what to choose?
You already know what to choose as the first layer, so what now? It's time for insulating layer, which plays a key role during winter adventures in the mountains. Why is it so important? Its function is to trap the heat produced by the body and to protect against heat loss to the outside. You have several options: lightweight fleece jackets, down jackets and insulated sweatshirts that can be easily adjusted to suit the conditions and intensity of the activity.
-
A fleece jacket is a versatile option that provides great insulation while being breathable and lightweight.
-
Lightweight down jackets work well when you are resting or on very cold days, when you need extra warmth without noticeable extra weight.
-
Insulated sweatshirts or softshell jackets offer comfort and flexibility when it’s moderately cold outside.
It doesn't take much to fall into a trap when choosing a second layer. If you’re up for an intense hike, make sure the insulating layer is not too thick as you may end up overheating. Thicker insulation, on the other hand, will come in handy during a longer rest or less demanding part of the adventure.
What would we recommend as an insulating layer?
-
Hooded regular fleece jacket for men - black - warm and lightweight, perfect when worn underneath a jacket. Its advantage is the 4FWarm technology, which helps maintain optimal thermal comfort. A great model for mountain adventures.
-
Women's black down jacket with natural fill by Outhorn - this is another option. Natural fill makes this thin, lightweight jacket perfect as an insulating layer for winter mountain hikes.
-
Men's black zippered sweatshirt is a piece made of thick knit fabric (as much as 360 gsm), which can be a perfect choice for winter trips to the mountains. In addition, it will be a versatile piece that will work just as great as a part of casual outfits.
Outer layer - jacket and trousers
And finally, the outer layer. What to choose to avoid getting cold? Good jackets and trousers must effectively protect against wind, snow and rain while allowing the skin to breathe.
4F recommends pieces with the NeoDry membrane, which guarantees high water resistance (up to 20,000 mm water column) and excellent vapour permeability (breathability of 15,000 g/m²/24h). This ensures that moisture is quickly wicked away and you stay dry without feeling the cold.
If you appreciate lightweight and flexible items, the outer layer made of softshell fabric is a great solution. This material is windproof, resistant to light precipitation and very comfortable when you’re very active.
-
adjustable and detachable hood that you can make suitable for current weather conditions,
-
cuffed sleeves and legs to prevent the cold permeating inside,
-
a ventilation system under the armpits or on the legs that allows you to control breathability during intense exercise,
-
waterproof laminated zippers to protect against moisture.
Choose pieces with practical comfort-enhancing elements such as:
Hard facts? Here you are!
-
Women's red trekking jacket with a 10k membrane is a piece with taped seams and DWR coating that provides extra fabric protection against water. And these are just some of the many assets of this model.
-
Men's blue trekking rain jacket with a 20K+ membrane is a genuine heavy-duty piece. The NeoDry20K+ membrane effectively protects against heavy rain and the 3-layer laminate blocks wind and moisture. Taped seams and a DWR coating prevent the material from soaking through. What else? An integrated adjustable hood, two-way zipper and laminated zippers add comfort and protection. We could go on for hours - just take a peek at the product sheet and see for yourself.
-
Men's black trekking trousers with a 10K membrane - this is a proposition for those who do not like unpleasant surprises while hiking. The 10K/8K NeoDry membrane effectively protects against moderate rain and promotes breathability on the move, while the outer DWR treatment prevents the fabric from absorbing water and moisture from the environment. It’s your hiking companion for winter trips to the mountains.
Accessories necessary for a winter adventure
During a winter trip to the mountains, appropriate accessories are just as important as basic clothing items. They are often the make-or-break pieces when it comes to comfortable body temperature regulation and protection from the cold in places where most body heat escape.
Well-selected accessories will keep you warm and comfortable on any trail, even in the most harshest conditions. Choose proven pieces.
