The lightweight Stealth is a Bloc legend. It's a vital part of any kit bag providing demanding athletes the ultimate in performance and protection.

Moulded nose pads prevent slipping and improve comfort, control and performance. A comfortable lightweight flexible frame for high-speed pursuits. Perfect for skiing, cycling and shooting with maximum peripheral vision.

Three interchangeable lenses let you adapt to all sports and all weather conditions.

The three 100% UV protection lenses supplied are:
Clear (Category 0), to be used at night or in low light conditions - protects against foreign particles and wind penetration.
Citrus (Category 1), a high definition yellow lens ideally suited to low light conditions.
Ve5 (Category 3), the unique hue of this lens makes it a true all rounder, at home in the brightest conditions, whether on mountain, street or beach. The grey content ensures natural colour transmission and the vermilion enhances red, green and yellow, whilst eliminating a high degree of blue light. This increases perception of detail and dramatically reduces eye fatigue.

Comes in an attractive display box.
