Technical Cycling Jerseys

A good jersey makes all the difference when you spend hours on the bike. At Twenty One, we design and test our garments in real conditions in Girona and Barcelona, between the Costa Brava and the Pyrenees, where wind, humidity, and elevation changes demand maximum quality and performance.

Our collection of men's and women's jerseys combines ergonomic fit, technical fabrics, and functional details designed for road, gravel, indoor cycling, and mountain biking. Every panel and every finish is aimed at offering comfort, stability, and freedom of movement on rides and training sessions.

If you're looking for a cycling jersey that performs when the pace picks up and the ride gets longer, your choice starts here.

Types of cycling jerseys available

Summer Cycling Jerseys

Designed for the warmer months, they incorporate lightweight and breathable fabrics that promote ventilation and efficient sweat wicking. They are ideal for intense training sessions and long rides under the sun.

The construction prioritizes freshness, quick-drying, and freedom of movement, maintaining a stable fit even during prolonged efforts.

Winter Cycling Jerseys

Made with thermal materials and insulating membranes, they help maintain body temperature in cold conditions. Thanks to their breathability, they prevent moisture accumulation inside.

They are a solid option for winter training without compromising comfort or mobility. Explore winter jerseys here.

Mid-season jerseys

Designed for spring and autumn, they offer lightweight and versatile protection. Perfect for combining with vests or jackets when the weather changes during the ride.

How to choose your cycling jersey

Choosing the right cycling jersey depends on your level, discipline, and the conditions in which you ride.

According to your level and type of ride

• Performance: a more fitted and aerodynamic cut, designed for those seeking maximum performance.
• Light & Air: focus on lightness and ventilation for warm climates or intense sessions.
• Thermal: oriented towards training in low temperatures with a warm and stable interior.

If you train regularly on the road or gravel and prioritize efficiency, a technical fit and pocket stability are key. For indoor cycling or high-intensity sessions, moisture management is crucial.

According to the weather

• Summer: lightweight fabrics and ventilation panels.
• Winter: thermal materials with cold protection.
• Mid-season: lightweight long sleeves or combination with outer layers.

The weather can change quickly, so having an appropriate jersey improves performance and comfort on every ride.

Technical materials and construction

At Twenty One, we work with high-performance technical fabrics, selected for their breathability, elasticity, and resistance to intensive use.

Ergonomic fit and anatomical cut

The pattern is designed for the actual position on the bicycle. This reduces wrinkles, prevents chafing, and improves aerodynamic efficiency. In the women's collection, the cut is adapted to the female anatomy for greater comfort in the chest, shoulders, and waist.

Breathability and moisture management

The fabrics allow for efficient sweat wicking, keeping the body dry even during prolonged efforts. The combination of lightness and quick-drying contributes to a constant feeling of freshness.

Pockets and functional details

All models incorporate easily accessible back pockets for nutrition and accessories. Some include an additional zippered pocket. Finishes and flat zippers help improve comfort.

Size guide and fit

A cycling jersey should fit snugly but without restricting movement. If you are in doubt between two sizes, consult our size guide:

• Men's size guide
• Women's size guide

Choosing the correct size improves aerodynamics and prevents unnecessary folds.

Care and maintenance of the cycling jersey

To preserve the technical properties of the fabric:

• Wash in cold water.
• Avoid fabric softeners.
• Do not tumble dry or iron.
• Store in a dry, ventilated place.
