A cosmic view of the road ahead.

The latest ALBA OPTICS JUMBO is one of the most distinctive eyewear releases to arrive at Chainsmith — combining bold Italian design, exceptional visibility and practical performance for Australian riding conditions.

Handcrafted in Italy, the JUMBO was created for riders who demand more from their eyewear than simple sun protection. The oversized VZUM™ J-LENS platform delivers an expansive field of vision while maintaining a lightweight feel at just 26 grams. Whether you're rolling through the city before sunrise, climbing into changing mountain weather or riding under harsh Australian midday glare, the JUMBO is designed to adapt with you.

This version features the VZUM™ F-LENS FLM photochromic lens, developed to automatically respond to changing light conditions. The lens transitions between Category 1 and Category 3 protection depending on UV exposure, helping riders maintain clear vision through:

• early morning bunch rides
• shaded forest roads
• changing weather fronts
• bright coastal glare
• intense Australian summer sunlight

The pink-toned FLM lens enhances visual contrast while maintaining a bright field of view, helping improve reaction time when light conditions shift rapidly. For Australian cyclists who regularly begin rides before sunrise and finish under strong daylight, photochromic technology removes the constant compromise between low-light visibility and high-sun protection.

Three integrated ventilation ports within the VZUM™ J-LENS help reduce condensation and fogging during hard efforts, climbing and variable temperatures. The interchangeable lens system allows future lens upgrades while maintaining the clean aesthetic that has become synonymous with Alba Optics.

The lightweight TR90 frame combines durability with long-ride comfort, while adjustable temple tips allow riders to fine-tune fit and helmet compatibility.

Like much of modern Italian cycling culture, the JUMBO blends performance and emotion equally. It is technical without feeling clinical. Functional without becoming generic.

For Australian riders chasing long road rides, gravel adventures, alpine descents and everyday training, the JUMBO offers one of the most adaptable premium eyewear systems available.

At Chainsmith, we deliberately stock the photochromic FLM version because Australian riding conditions can change dramatically across a single ride. One lens. One pair of glasses. Broad versatility.

JUMBO. Ready to fly.

Light is a fundamental component that determines of all our choices. VZUM™ lenses have only one objective: to provide athletes with the maximum visual experience in all weather conditions and on all types of terrain. The range of colours carefully developed by ALBA Optics aims to enhance colour saturation and balance visual contrasts, thus increasing the perception of sharpness and details.

The material of which VZUM™ lenses are composed of is a durable ultra-light polycarbonate. This offers fundamental protection to avoid straining eyes and the lenses maintain these characteristics for the total cycle of use. Thanks to this versatility, VZUM™ lenses offer the best sports experience ever.
