Winter cycling requires a thoughtful gear selection, and a crucial component of your cold-weather kit is the right base layer. When the temperatures drop, maintaining optimal body temperature becomes even more critical for both performance and comfort. That's where our winter cycling base layers come into play.

Designed for the coldest conditions, our winter cycling base layers excel in regulating body temperature by providing an additional layer of insulation. The innovative design ensures that you stay comfortably warm without compromising your ability to move freely on the bike. The base layer acts as a thermal barrier, effectively trapping heat close to your body to shield you from the biting cold.

Made from advanced materials, our winter cycling base layers prioritize lightweight and breathable fabrics that actively wick away moisture. This feature is essential in preventing sweat buildup, which can lead to discomfort and even hypothermia in extreme conditions. Whether you're facing cool or sub-zero temperatures, our base layers work tirelessly to keep you dry and insulated.

Say goodbye to chafing and discomfort during your rides with our winter cycling base layers. The soft, yet durable, materials eliminate the risk of irritation from seams or rough textures, allowing you to focus on the road ahead. Even the days of feeling restricted by bulky layers seem distant: our base layers are designed to move with you, ensuring an unrestricted and natural riding experience.

Furthermore, our base layers are versatile and can be used for other winter activities as well. Their design and materials make them suitable for running, skiing, or hiking in cold conditions.

Investing in a high-quality winter cycling base layer is not just a luxury, but it is a necessity for peak performance in cold conditions. Don't let the cold weather hold you back. Our base layers are engineered with years of expertise and research, promising to make a significant difference in how you face the challenges of harsh weather. Embrace the warmth, stay comfortable, and elevate your winter cycling adventure with our winter cycling base layers. Your cold-weather rides will never be the same again.

When searching for winter cycling base layers, people tend to look for a variety of attributes. Here are some common attributes you might consider when choosing our winter cycling base layers.
Maintaining a comfortable body temperature in cold conditions is challenging. Our base layers help regulate body temperature by providing insulation. They are made with materials such as polyester and merino wool, capable of trapping and retaining body heat ensuring extra warmth in the most extreme weather conditions.
Sweating is still a concern even in cold weather, and proper moisture management is crucial in winter cycling base layers for staying warm, dry and comfortable. A damp base layer can increase heat loss, which is especially dangerous in colder temperatures. When the body is wet, the cooling effect is more pronounced, making it essential to keep moisture away from the skin. Inadequate moisture control can also lead to discomfort and chafing, particularly in sensitive areas. A base layer with effective moisture-wicking properties can prevent these issues by transporting sweat away from the skin. To keep cyclists dry and comfortable, we often incorporates moisture-wicking fabrics that efficiently move sweat away from the skin, preventing the build-up of moisture. Through polyester and polypropylene yarns, our base layers can effectively wick moisture away from the skin keeping the body warm and preventing hypothermia.
A lightweight cycling base layer is important for enhancing the comfort and performance of a cyclist. It allows for better breathability and moisture management. It is also more flexible and form-fitting, reducing bulkiness and improving mobility on the bike.
A well-fitting cycling base layer is essential for comfort, performance, and health. It should fit snugly, hug the skin, and cover the lower back. In a few words, it should fit close to the body. A proper fit prevents chafing and discomfort, avoids cold exposure, and regulates body temperature. If the base layer is too tight, it limits movement and breathing, while if it's too loose, it creates friction and irritation. In cold weather, a base layer that is too loose also allows cold air to seep in. Our well-fitting base layers help you stay comfortable, dry, and perform at your best while riding.
Breathability is crucial in a cycling base layer. While providing insulation, our base layers are usually designed to be breathable, allowing excess heat and moisture to escape, preventing overheating during intense rides. By preventing overheating, which can lead to more fatigue, they guarantee improved performance. Breathable fabrics also prevent discomfort by keeping you dry during a ride.
A good winter cycling base layer should obviously be comfortable to wear, especially during long rides. In practice, this means it should be made with breathable and quick-drying materials, able to manage moisture and regulate body temperature. In addition, features such as right fit, antibacterial properties, odor-resistant technology and flatlock seams that lie flat against the skin (reducing irritation) are all important for added comfort and performance. You'll find all of these in our winter cycling base layers.

When we consider our winter cycling base layers, we can divide them into two different groups depending on their weight, thermal or mid.

Made with warm fabrics such as SottoZero Fleece multi-denier 100% polyester or wool, our thermal-weight base layers are ideal for cold and extreme cold conditions, including temperatures below zero. We're talking about the Flanders Warm Long Sleeve for men and women, the Flanders Warm Neck Warmer, which features higher than normal neck that can be pulled up to act as a neck warmer, and the Bandito Wool LS Baselayer for men and women.

More focused on breathability and lightness, our mid-weight base layers are suitable for cool/mid-season conditions or winter days when temperatures are not too low. Among them are the Prosecco Tech Long Sleeve for men and women, the Prosecco Tech Short Sleeve for men and women, the Miracolo Wool Long Sleeve for men and women, the Bandito Wool SS Baselayer and the Core Seamless Base Layer LS.

In addition to the winter cycling base layers mentioned so far, which are normally used as first layers in contact with the skin, we've designed a garment with the function of a second layer between a jacket and a base layer. We are talking about the Cold Days 2nd Layer for men and women, made of Polartec® Alpha® 90 fabric to ensure maximum thermal insulation. This feature makes it ideal in harsh conditions and temperatures even below zero. The presence of the high collar provides additional protection and emphasizes the attention to detail that has always characterized the Castelli brand. Moreover, the Cold Days 2nd Layer offers cold protection without compromising on lightness and breathability, and it works effectively when paired with all our winter cycling base layers: Prosecco, Flanders, Bandito, Miracolo or Seamless.
