The first layer is super important.
Of all the clothing worn in winter, the base layer, which is in close contact with the skin, is the most important item that affects body temperature regulation. In winter, sweat and cold can make you feel ill, so the performance of your clothing can make or break your ride.
However, it may be difficult to know which one to choose, as the fabric material and thickness vary from brand to brand. Therefore, to help you find a base layer that suits your riding style, we will introduce how to choose and recommend products.

1. Types of winter base layers
Base layers are selected based on fabric thickness and material.
It can be used in all seasons and can be layered with other base layers in the middle of winter. It dries quickly, is easy to move around in, and causes the least amount of stress.
The most versatile medium thickness in fall and winter. Its moderate thickness does not hinder movement, making it stress-free even in cooler temperatures.
This thicker material is ideal for riding in extremely cold climates or for low-intensity winter rides. Because of this, it sacrifices quick-drying and heat-dissipating properties, so it is not suitable for high-intensity training rides.
The material itself absorbs moisture and generates heat, providing excellent heat retention, as well as a pleasant texture and high antibacterial properties.
Because it is a natural material, it is sometimes said to be less quick-drying than synthetic fibers, but since sports merino is blended with synthetic fibers, there is little difference in functionality.
Its greatest feature is its excellent quick-drying properties. It allows perspiration to permeate the fabric and prevent it from returning wet, making it comfortable even after an intense ride.
Some materials are as good as wool in terms of heat retention.
2. How to choose & combine base layers
Select thickness and material according to the way you ride.
The appropriate base layer depends on the individual’s riding style. For high intensity or high temperatures, a lightweight base layer should be used, and layers should be added as needed, while a midweight or heavyweight layer should be selected for lower temperatures.
The material itself depends on your preference for texture, with merino being the best choice for comfort and synthetic fibers being the most cost-effective.
Choose a tight fit
The rule of thumb is to choose a size and silhouette that adheres closely to the skin so that it can absorb sweat.
You may choose a mountaineering brand, but be aware that they may have a relaxed fit that does not adhere closely.
Wear layers as needed
Although a single winter base layer can be used alone, layering a summer dry layer underneath is also effective in preventing chills.
Moisture absorbed by the dry layer is absorbed by the winter base layer (second layer), making it difficult to sweat cold.
If you are worried about getting sweaty cold with one winter layer, try wearing two layers in combination with a summer layer. You will feel more comfortable than usual.
