The Castelli Pro Thermal Mid LS Men's Cycling Jersey (Electric Lime) is a high-performance long-sleeve cycling jersey engineered for riders who demand professional-level comfort, aerodynamic efficiency, and reliable thermal protection during cool-weather riding. Developed with input from elite cyclists and built using Castelli's innovative Italian textile technology, this jersey is designed to excel in autumn, spring, and mild winter conditions while maintaining the lightweight feel and freedom of movement expected from premium cycling apparel.
Unlike bulky winter jackets, the Pro Thermal Mid LS strikes the perfect balance between insulation and breathability. Constructed with Castelli's advanced mid-weight thermal fabric, the jersey features a soft brushed fleece interior that traps a thin layer of warm air close to the body, helping regulate core temperature without causing overheating. This technical fabric provides excellent warmth during chilly morning rides and cool descents while remaining highly breathable when the intensity increases on climbs or during interval training.
One of the jersey's biggest advantages is its exceptional thermoregulation system. As your body generates heat, the moisture-wicking fabric actively transports perspiration away from the skin to the outer surface, where it evaporates quickly. This process keeps you dry, minimizes sweat build-up, and helps prevent post-exercise cooling, allowing you to remain comfortable throughout long endurance rides and rapidly changing weather conditions.
Designed around an aggressive riding position, the Castelli Pro Fit ensures a streamlined silhouette that reduces aerodynamic drag while providing unrestricted mobility. Multiple ergonomic panels and four-way stretch construction conform naturally to the rider's body, eliminating unnecessary fabric movement and improving efficiency on the bike. Whether you're climbing steep gradients, sprinting to the finish, or maintaining an aero position on flat roads, the jersey moves seamlessly with every pedal stroke.
Temperature regulation is further enhanced by the full-length YKK® Vislon® zipper, one of the most trusted zippers in premium cycling apparel. Riders can easily adjust ventilation during demanding efforts or fully zip up for additional warmth when temperatures drop. The zipper operates smoothly with one hand, making on-the-bike adjustments quick and effortless.
Practical storage solutions make the jersey ideal for long-distance riding. Three generously sized rear cargo pockets provide secure space for energy gels, nutrition, smartphones, mini tools, spare gloves, lightweight jackets, and ride essentials. An additional zippered security pocket safely stores valuables such as keys, cards, cash, or identification, ensuring peace of mind during training rides, sportives, and gran fondo events.
The silicone gripper waistband keeps the jersey securely positioned throughout every ride. Even during aggressive riding positions or extended periods in the drops, the jersey remains stable, preventing bunching and ensuring easy access to the rear pockets while preserving its aerodynamic profile.
Safety is an important consideration in the Pro Thermal Mid LS. Strategically positioned reflective details improve rider visibility in low-light environments such as early morning starts, evening commutes, foggy roads, or overcast weather. These reflective accents integrate seamlessly into the jersey's clean design while enhancing on-road safety.
The standout Electric Lime colorway not only delivers a bold and energetic appearance but also significantly improves daytime visibility. The bright fluorescent finish helps riders remain more noticeable to motorists and fellow cyclists, making it an excellent choice for road riding where visibility is essential. Combined with Castelli's minimalist styling, the jersey offers a modern, professional aesthetic that pairs effortlessly with black bib shorts, thermal tights, gloves, overshoes, and jackets.
