2025 2026 Windy City ThunderBolts Bolts #10 Jersey | Embrace the “Electric”

The ThunderBolts’ 2026 rebrand is the biggest news of the Frontier League offseason, and this jersey is the centerpiece. The team has embraced the “Bolts” shorthand, and this design screams energy. The main body features a striking, dark charcoal and black base, overlaid with a dynamic, jagged lightning bolt pattern in a cool, electric blue. This isn’t a subtle design; it’s meant to be seen from the grandstand, representing the high-tension power that fuels the team and the fans.

Across the chest, the new “BOLTS” wordmark is rendered in a custom, blocky, electric-inspired font, making it clear this is a new chapter. The button-down front and athletic cut provide a classic baseball silhouette, while the modern design ensures it stands out in any crowd.

This jersey is a heartfelt ode to the unique character of the ThunderBolts’ home. The design is audacious, celebrating what makes the team uniquely theirs. The logos on the sleeves, including the new “WC” mark, are fully integrated into the design, showcasing the comprehensive new identity.

On the back, the 2026 Windy City ThunderBolts “Bolts” #10 Jersey features the number 10 in the same custom electric-blue font, set against the mesmerizing lightning bolt pattern. Above the number, a stylized logo of a player swinging for the fences encapsulates the power and ambition of the new “Bolts” era. The #10 is the quintessential fan number—representing you, the “10th man” on the field, the heart of the team’s support system. It’s a classic, player-agnostic number that will never go out of style.
