The most comfortable base layers

Thanks to the use of innovative and technical fabrics, our brand succeeds in combining comfort, quality and reasonable prices. In merino wool, in silk or in fibre of bamboo, all of Cimalp's thermal and technical base layers deliver comfortable warmth, a optimal insulation and moisture-wicking properties that guarantee hygiene and ease of movement. Our extreme cold base layers also guarantee an optimal fit and a ease of movement in your movements. What's more, they are durable over time. So don't go without them — they'll soon become essential. 

Our thermal ski base layers: perfect ergonomics

Whether they are long johns to wear under your extreme cold ski trousers or tops, the cuts Cimalp ski base layers always offer perfect ergonomics to support your favourite activity. They can be worn as women's and men's ski base layers, or as extreme cold base layers. Always developed with user comfort as a priority, the fabrics Cimalp uses for its thermal base layers are soft to the touch, benefiting from flat seams, low friction and a treatment antibacterial and anti-odour. The perfect companion for your ski outfit, they should of course be worn as the first layer if you follow the well-known 3-layer rule for your trekking outfit !

What are thermal base layers for?

Thermal base layers are designed to protect your body against cold temperatures during outdoor activities. Like a t-shirt, they are designed to be worn as a first layer and are made from warm, lightweight and breathable materials.

They also help regulate your body temperature and keep you warm when exposed to cold temperatures. They efficiently wick away moisture for maximum comfort. They are designed to be worn directly against the skin and are generally made from synthetic materials or merino wool, which have insulating and breathable properties. Finally, they are very lightweight and compact, making them easy to pack in your backpack. They are also highly versatile and can be worn in a variety of weather conditions, whether in cold and dry conditions or in the rain.

Equally suited to athletes and professionals, the thermal base layer can serve as workwear or as a garment for your sporting activities.

How do I choose the right size?

It is important to choose a size of thermal base layer that fits your body well without being too tight. Base layers that are too tight can restrict blood circulation, which can be dangerous during intense physical activity. It is also important to choose an appropriate length based on your height.

What are the different materials for thermal base layers?

There are several types of materials used for thermal base layers. The most common are polyester, merino wool and nylon, as well as fibre blends. Each material offers advantages and disadvantages in terms of warmth, breathability and weight — it is important to choose the material of your thermal base layer based on the weather conditions and activities involved. For example, merino wool is ideal for low-intensity activities and cold conditions, while polyester may be preferable for more intense activities and milder conditions.

Are thermal base layers suitable for all outdoor activities?

Yes, thermal base layers can be used for a wide range of outdoor activities, including hiking, skiing, snowboarding, running, mountaineering and more. Even in mid-season, a long-sleeved t-shirt or a lightweight base layer is a great way to keep the cold at bay. They are particularly useful when you are exposed to cool temperatures and windy conditions. Choosing the right sports t-shirt or thermal base layer matters — so get it right!
