What's The Difference Between The Julbo Shield and Shield M

What's The Difference Between The Shield and Shield M

The Shield and Shield M are versatile and lightweight multi-sport sunglasses. Designed for the mountains, but comfortable in any environment. But how do you determine which pair is right for you? Read on to learn the differences between the Shield and Shield M.

Lightweight. Full coverage. Versatile. That’s the Shield and Shield M, our multi-sport sunglasses that are loaded with technical features and available in a variety of lenses. And while they’re designed as glacier glasses for high-mountain utility and protection, they’re equally suitable around town or even on the water, thanks to removable side shields.

But what’s the difference between the two? 



Built for anything you can toss at them, the Shield glacier glasses perfectly combine on-mountain utility and off-mountain style.

The Frame: The Shield’s lightweight polycarbonate frame provides full coverage, while Air Flow venting at the top and bottom of the frame prevents fogging during strenuous efforts.

Curved temples equipped with Grip Tech and Nose Grip technology provide a comfortable and secure fit with ample protection from harmful sunlight and glare.

Like the Shield M, the Shield comes with removable synthetic side shields that are lightweight, soft and resistant to the elements.

A silicone accessory cord is also included with the Shield and Shield M to ensure they’re never too far away. 

The Shield offers a larger fit than the smaller Shield M.

Lenses: The Shield’s large lenses are available with polycarbonate Spectron lenses or REACTIV Photochromic lenses.

Spectron lenses were designed to offer powerful protection for mountain trekking and mountaineering, with an anti-reflective coating to improve visual comfort and a flash finish that improves the filtration of visible light. While the Spectron 3 Polarized lens offers additional protection from glare. The Shield is equipped with Spectron 3 Polarized and Spectron 4.

REACTIV Photochromic lenses adjust from light to dark depending on light levels, making them ideal for constantly changing conditions. Constructed from Trivex, a material used for helicopter windshields, REACTIV lenses offer unparalleled durability and optical quality. In addition, their NTS (Non-Temperature Sensitive) technology guarantees a constant photochromic range, whatever the temperature.

The Shield comes equipped with the REACTIV 2-4 Polarized lens 



The “M” in Shield M stands for “medium,” meaning it is a slightly smaller version of the Shield. Loaded with the same technology and features as the Shield, the Shield M are ideal for individuals looking for smaller-fitting mountain sunglasses.

The Frame: Like the Shield, the Shield M has a lightweight polycarbonate frame equipped with Air Flow venting technology. The temple arms, which feature a soft Grip Tech material, are curved to offer an ergonomic fit. The Shield M also has Grip Nose Pads for additional comfort and security.

Additionally, the Shield M features removable synthetic side shields that protect from harmful sunlight and glare.

Lenses: The Shield M’s wrap-around styling offers complete protection while maintaining a modern look. Like the Shield, the Shield M is available with either Julbo’s REACTIV Photochromic lenses or polycarbonate Spectron lenses.

Spectron lenses are designed to offer powerful protection for mountain trekking and mountaineering, with an anti-reflective coating to improve visual comfort and a flash finish that improves the filtration of visible light. The Spectron 3 Polarized lens offers additional protection from glare and reflected light. 

REACTIV Photochromic lenses adjust from light to dark depending on light levels, making them ideal for constantly changing conditions. They combine the advantages of mineral and polycarbonate lenses: optical quality, scratch resistance, strength and lightness. In addition, their NTS (Non-Temperature Sensitive) technology guarantees a constant photochromic range, whatever the temperature.
