Cycling base layers help regulate body temperature and manage moisture during riding, making them one of the most important pieces of clothing for comfort in both hot and cold conditions. Worn underneath jerseys and jackets, base layers improve breathability, warmth and overall comfort for road cycling, mountain biking, gravel riding and commuting.
Why Choose Cycling Base Layers?
Base layers are designed to sit close to the skin and move moisture away from the body during riding, helping riders stay drier and more comfortable through changing temperatures and riding intensities. Lightweight summer base layers help improve cooling and sweat management, while thermal winter options add insulation for colder rides and harsh weather conditions.
What to Look for in Cycling Base Layers
- Fit: Base layers should fit close to the body for effective moisture management and comfortable layering beneath jerseys and jackets.
- Temperature range: Lightweight sleeveless and short sleeve options suit warmer weather riding, while thermal long sleeve base layers provide added insulation during colder conditions.
- Fabric: Moisture-wicking synthetic materials dry quickly and regulate temperature well, while merino wool blends offer natural warmth, breathability and odour resistance for year-round riding.
Base layers work best as part of a complete layering system alongside jerseys, gilets and jackets to help riders adapt to changing weather conditions throughout the year.
