Explore men’s base layer tops
Men’s base layer tops are worn closest to the skin, so they need to deliver on both comfort and temperature-regulating performance. The right choice depends on your needs in the outdoors, as different activities demand different cuts, fits and materials. Whether you need a base layer for walking, skiing or climbing – in cold or warm climates – or simply an extra layer under a shirt or fleece for your daily commute, you’ll find it here.
Why choose a Fjällräven men’s base layer?
Our body temperature can change often in the outdoors. Wearing the right combination of base layer, mid layer, insulation garment, and shell jacket is the key to ensuring your comfort in nature. To help you build the layering system you need, every piece is carefully considered, with seams placed to minimise chafing and fits shaped for optimal layering. All are made from selected materials to handle both low- and high-intensity activities and are designed to serve you season after season.
Merino wool base layers: Natural warmth and breathability
One of the most popular materials for men’s base layers is merino wool. It’s a remarkable natural fibre that is breathable; regulates body temperature and keeps you warm even when damp. It’s also naturally antibacterial and odour-resistant, helping you stay fresh even when working hard.
Beyond its functional qualities, wool is renewable and biodegradable. We offer men’s merino wool base layers in both 100% merino wool and blends, giving you the freedom to choose the qualities that best suit your needs.
Find the right base layer top for outdoor performance
For skiing or climbing, when you need warmth without overheating, our 100% merino wool tops for men are ideal. Merino base layer tops breathe and wick away moisture, helping you stay dry and warm even during exertion – perfect for cold-weather activities. For trekking in colder weather, we offer merino wool blended with hardwearing polyester, to keep you warm when it’s chilly or you’re at rest and cool when you’re actively walking. For warm treks, choose a technical jersey base layer with a hood for built-in sun protection, quick-drying performance and maximum ventilation.
FAQ
What is a base layer top for?
A base layer shirt helps regulate body temperature by insulating in cold weather and wicking away sweat during exertion. As the layer worn closest to your skin, it needs to be soft, flexible, and breathable for all-day comfort.
What to wear on top of a base layer?
Over a base layer you’ll want to wear a mid layer such as a warm jumper, light insulation jacket, or shirt, depending on activity and temperature. It should allow moisture to escape while retaining warmth, and be easy to remove if it gets too hot. The mid layer can then be followed by an insulation layer or a shell jacket that protects against wind and rain.
How warm is 100% merino wool?
Merino wool is naturally insulating, trapping and holding body heat, making it a reliable base layer material for cold conditions.
