Long-sleeved thermal shirts

Long-sleeved cycling jerseys are an essential part of any cyclist's kit when riding in colder conditions - be it in autumn, winter or early spring. Their main task is to keep the body warm, wick away sweat and ensure comfort throughout the ride.

What are the main features of long-sleeved thermal underwear?

The specific features of thermal T-shirts are:

Functional materials: Made from technical fabrics such as polyester, polyamide, elastane or merino wool, which provide excellent insulation and are also breathable.
Quick drying and moisture wicking: Thermal shirts actively wick sweat away from the body and prevent hypothermia.
Comfortable fit: The elastic and anatomically shaped fit adapts to the body, does not restrict movement and is easy to wear under other layers (e.g. a cycling jersey or jacket).
Flat seams: Minimize skin irritation and increase comfort during prolonged wear.
Extended back: Protects the lower back even when leaning forward on the bike.
Long sleeves: Protect your hands from cold and wind.

Who are thermal shirts intended for?

Long-sleeved thermal shirts are designed for:

Cyclists of all levels (recreational and performance)
For road cycling, MTB, gravel and bikepacking
Ideal as the first layer in a layered dressing system

What are the main benefits of wearing thermal underwear?

Thermal comfort without overheating
Also suitable for off-bike use - for running, hiking or winter sports
Light weight and compact – easy to pack into a backpack

What is the difference between a merino wool and synthetic thermal shirt?

Merino wool: A natural material, it insulates well, absorbs odours and is pleasant to the touch. It dries a little slower.
Synthetics (e.g. polyester): Quick-drying, durable and lightweight. Can get smelly faster and is less warm at rest.

How should I care for a thermal T-shirt?

Wash it at low temperatures (usually up to 30 °C), without fabric softener and according to the manufacturer's instructions. Wash merino t-shirts with a special detergent for wool.

Is a thermal shirt sufficient as a single layer?

In slightly cold conditions, yes. However, in winter it is recommended to combine it with other layers - e.g. jersey, jacket, or vest.

What material is best for intense rides?

Synthetics are ideal for intense sports, as they dry quickly and effectively wick away sweat. Merino is also beneficial for slower rides or bikepacking.
