Red Bull SPECT Eyewear's Fuse are sports sunglasses built around the Flow 2.0 system: the lens floats freely, detached from the frame, and transforms with a single gesture. With a soft, contoured top line and an ultralight bio-based G850 frame, this model is designed for cycling and running, yet remains restrained enough for city wear.

Key features

• Flow 2.0 system: the lens is decoupled from the frame and floats freely; it can be activated or deactivated by hand
• Activated, the lens moves away from the frame: maximum ventilation, vibration dampening, less fogging
• Deactivated, the lens closes against the frame: aerodynamic silhouette and maximum protection against sun and debris
• Bio-based G850 frame: ultralight, hypoallergenic, and flexible
• Wraparound polycarbonate shield lens with mirror finish, category 3 (8 to 18% light transmission)
• 100% UV protection
• Rubberized, adjustable, and very flat temple tips to prevent contact points with the helmet
• Adjustable nose pads with rubber reinforcements
• V°MAX ventilation: open frame design and vents in the tips to dissipate hot air
• Frame width 138 mm, temple length 130 mm
• Lens top line positioned by Red Bull SPECT as being particularly flattering on narrower faces

Materials
