SUMMARY

1. Introduction

2. NXT technology

3. Julbo high-performance lenses

Better technology for better performance, as always.

A past master in the art of lenses, Julbo continues to lead the field with cutting-edge solutions perfectly adapted to the requirements of high-level sport. Our technical lenses Falcon, Octopus, Cameleon, Zebra and Zebra Light continue to use NXT Technology for unrivalled performance and the most effective solution for each discipline and each user.

2. NXT TECHNOLOGY// a lens for all occasion

The technology was initially developed for the US Army in the 1990s for two purposes:

To protect against bullets

To guarantee the finest optical quality

NXT is used in the most extreme conditions:

Aeronautics:helicopter windscreens

Motor sports:helmet visors

Police forces:riot shields

2 // NXT, a high-tech lens

NXT is made from Trivex, the most effective material on the optics market,combining the advantages of mineral and organic materials.

An optical quality close to that of mineral glass

Crystal clear images

Stronger than polycarbonate

The lightest

2 // A unique manufacturing processNXT is produced by casting at moderate temperature rather than by injection molding.

2 // NXT, produced by casting

NXT (castin)

POLYCARBONATE (injection)

Temperature Moderate temperature High temperature

Polymerisation time 15 to 20 hours A few seconds

Photochromic treatments inside the material External surface of the lens

Procedure Meticulous control oftemperature, viscosity and

hydrometry

No mechanical stress

2 // With NXT, get the competitive advantage

NXT lens characteristic:

LightweightWith a density of 1.11, the NXT lens is the lightest lens currently available.

Superior optical qualityNXT is cast at moderate temperature: no residual internal stress. The geometry of the lenses is homogenous: no image distortion.

UnbreakableAn NXT lens can withstand the impact of a 7mm bullet travelling at 165 kph.

2 // Get the competitive advantage

NXT lens characteristic:

Crystal clear image:the ABBE number of the NXT lens is 45. Its chromatic aberration is 1.5 times lower than polycarbonate. Vision is clearer.

Resistance Mechanical strength : NXT lenses withstand repeated stresses.

NXT lenses have withstood torsion tests applied for 10,000 cycles. Resistance to solvents : NXT withstands the effects of acetone.

An NXT lens subjected to petrol vapours for 10 minutes remains intact.

High scratch and cracking Resistance

Longlasting material treatment: NXT lenses undergo an in-mass photochromic process. The polarizing films of NXT lenses are inserted into the centre of the lens between two layers and are therefore protected against any risk of delamination.

2 // The best of optical quality

NXT technology guarantees optimum optical quality, great visual clarity and exceptional resistance to wear. NXT lenses are unbreakable and ultra-lightweight.

Photochromic: protection category 1 to 3. Fast activation speed Exceptional anti-fog coating: no condensation, maximum longevity. External oil-repellent coating: prevents marking and facilitates water runoff. Brown: accentuates relief.

This photochromic and anti-fog lens, developed for the Speed range adapts to light levels at any time of day.

FROM DAWN TO DUSK

Lens Selector

USERSAll those who practice active outdoor sports: trail running, mountain biking,climbing, skiing.

USES- varied situations: snow, in and around the forest, footpaths, open spaces- frequent changes in light level- intense effort

3 ou 4

Photochromic: protection category 2 to 4. NTS technology: the lens gets darker or lighter regardless of the temperature. Polarizing: eliminates snow glare, ensuring purity of vision. Exceptional anti-fog coating: no condensation, maximum longevity. External oil-repellent coating: prevents marking and facilitates water runoff. Brown: accentuates relief.

This photochromic, anti-fog and polarizing lens, developed for the outdoor range, is designed for use in mountain and desert environments.

PURE ALL-TERRAIN VISION

Lens Selector

USERSAll those who practice mountain sports: mountaineering, trekking, skimountaineering.

USES- Intense glare due to reection (snow, ice, desert) or altitude- reections (snow, ice)- changes in light level- temperature variation

Photochromic: protection category 2 to 4. Pure Polarising Filter (PPF): Highly durable varnish finish / optimum optical quality. NTS technology: the lens gets darker or lighter regardless of the temperature. External hydrophobic coating: makes water run off the lens, improving visibility. Internal and external oil-repellent coating: prevents finger or grease

marks and makes cleaning easier. Grey: faithful color reproduction.

This photochromic, polarized and water-repellent lens, developed for the Nautic range, is suitable for all water sports.

A CLEAR VIEW TO THE HORIZON IN ALL WEATHERS

Lens Selector

USERSAll those who practice water sports: sailing, dinghy sailing, canoeing and kayaking.

USES- On the sea, on lakes or in white water:° the need to be able to see in spite of the reections of sun on the water° water spray° changing light conditions according to the weather- Holidays beside the water (sea or lakes)

Photochromic: protection category 2 to 3. Polarizing: eliminates glare from all reflective surfaces (water, tarmac, glass etc.)

and provides the purest of vision. Anti-reflective coating: reduces eyestrain and eliminates interference glare. Internal oil-repellent coating: prevents finger or grease marks and makes

cleaning easier. BWS (Behind the Windshield) : the lens will get darker behind a

windshield and is particularly suitable for driving. Copper: accentuates contrasts, more comfortable vision.

This lens, developed for the Travel range, is multipurpose and recommended for driving.

CLEAR VISION AT ALL TIMES
