Ideal for riders who want premium shield-style sunglasses with full coverage, a stable fit and a bright-light lens for road, gravel or MTB use.
The 100% S3 sits right in the sweet spot for riders who want the bold look and big coverage of modern shield glasses without an overly bulky feel. The semi-rimless design keeps your view open, the 5.5-base cylindrical shield lens gives broad peripheral vision, and the built-in dual air vents help move air through the lens to cut down fogging when the effort goes up.
For bright Australian riding conditions, the HiPER® Royal Blue Mirror lens is a smart match. It is built to boost contrast and depth perception, while the Ultra HD™ construction aims to keep your view clear and distortion-free. You also get the practical extras that matter in real use: a replacement lens, a microfibre cleaning bag, and an alternative-fit nosepad so you can fine-tune the fit straight out of the box.
In day-to-day riding, the S3 shape has built a strong reputation for coverage, durability and easy lens swaps. It is a particularly good option if you want one premium pair for road, gravel and MTB use, or if you simply prefer a larger lens shape that shields your eyes from wind, dust and trail debris better than smaller performance glasses.
HiPER® Royal Blue Mirror lens
Built for bright conditions, with contrast-boosting optics that help terrain, road texture and detail stand out more clearly.
Large shield-style coverage
The S3 shape gives a broad field of view and better protection from wind, dust and spray than smaller lens designs.
Semi-rimless construction
Keeps the feel lighter and helps you look through the lens rather than at frame edges.
Dual lens vents
Built-in venting promotes airflow to reduce fogging during climbs, hard efforts and variable weather.
Ultra Grip Rubber contact points
Helps the glasses stay put when you are sweating, sprinting or riding rougher surfaces.
Durable polycarbonate lens
Impact-rated, hard-coated and treated to shed water, oil and grime more easily in mixed conditions.
Prescription-ready option
Compatible with the 100Percent RX Carrier if you need a prescription setup without changing the overall S3 platform.
Useful extras included
Comes with a microfibre bag, alternative-fit nosepad and replacement lens for more flexibility across conditions.

What's included
HiPER®
We'd recommend HiPER® if you want stronger contrast, richer colour and more trail or road detail at a glance. It helps you read terrain more clearly and improves depth perception so changing light is easier to manage.
Ultra HD™
This lens tech is built to keep your view crystal clear, so you can stay focused on the road, trail or bunch without distracting haze or distortion.
Hydrophobic + Oleophobic lens treatment
This treatment helps water, oil and dirt bead off the lens, so your glasses stay cleaner and easier to look through in mixed conditions.
Grilamid TR90
This lightweight frame material gives you a strong, durable feel without adding unnecessary bulk, making long rides more comfortable.
Ultra Grip Rubber
The nose and contact points stay soft and secure, helping the glasses hold their position even when you're sweating hard.
Great for
Maybe not for
The S3 is a larger-coverage model, so it generally suits riders who like a bold shield fit. Review testing suggests smaller heads can find the brow sitting close to the helmet and the arms may interact with some helmet retention cradles, so it is worth checking helmet compatibility if your fit is already tight. Includes an alternative-fit nosepad for extra adjustment. Prescription use requires the 100Percent RX Carrier, sold separately.
vs Oakley Sutro
The Sutro is another benchmark oversized cycling sunglass with excellent optics and a very secure feel, but it uses a full-circumference frame and typically comes with fewer extras.
vs Smith Wildcat
The Wildcat is a premium hybrid shield design that has been praised for working well across hot road rides, gravel and MTB, but it sits at a higher price point in Australia.
vs 100% Hypercraft
If you love the 100% look but want a lighter, more minimal option for hot-weather riding, the Hypercraft is the obvious step across within the same brand.
Best lens use case
The 16% light transmission, CAT 3 Royal Blue Mirror lens is best for bright daylight riding. If most of your rides start early, finish late or stay under tree cover, the included replacement lens adds useful flexibility.
Helmet fit check matters
Because the S3 is a large-coverage design, riders with smaller heads or low-sitting helmet cradles should check temple and brow clearance before committing. It is a great shape when it fits, but it is not a tiny sunglass.
A good multi-discipline option
This is one of those glasses that makes sense if you swap between road, gravel and MTB. The big shield helps with wind on the road and debris protection off-road, so you do not need separate glasses for each bike.
Easy maintenance pays off
The hydrophobic and oleophobic treatment helps keep the lens cleaner, but mirrored lenses still reward careful handling. Use the included microfibre bag for storage and cleaning to keep the coating looking its best.
