Triumph Triaction Underwire Sports Bra - High Impact Black

Triumph Triaction Underwire Performance Sports Bra

The Triumph Triaction Performance Bra delivers high-impact support for larger cup sizes during intensive workouts. This underwire sports bra in black with grey piping combines Triumph's 130+ years of lingerie expertise with performance technology designed specifically for women who need reliable bounce control at the gym.

High Impact Support for C-F Cup Sizes

Engineered for extreme bounce control, this performance bra features a rigid top panel with structured lining that significantly reduces movement during high-intensity activities like running, HIIT, and cardio training. The underwire construction provides encapsulation support, holding each breast individually for maximum stability without the compression-only approach of standard sports bras.

Breathable Eco Fabric Technology

The innovative eco fabric construction allows superior breathability to reduce sweating during workouts. Moisture-wicking properties keep you cool and dry, while the quality materials ensure softness, comfort, and prolonged durability through repeated wear and washing.

Key Features

• Underwire design for enhanced support and bounce control
• Rigid top panel with structured lining for stability
• Breathable eco fabric with moisture management
• Black colorway with grey piping detail
• Hook-and-eye back closure for adjustable fit
• Designed specifically for larger cup sizes C-F

Designed for Larger Busts

Unlike generic sports bras sized S-M-L, the Triaction Performance uses traditional bra sizing to ensure proper fit and support for fuller busts. The underwire and structured cups prevent the "uni-boob" effect while providing the encapsulation larger cup sizes need for comfortable, distraction-free workouts.
