Ideal for riders and active users who want premium shield-style coverage, strong contrast in bright light and a fit that feels a little less oversized than the biggest race-style sunglasses.
If you like the look and coverage of modern shield-style riding glasses but don’t want something overly huge on your face, the 100% S2 is a very easy pair to recommend. It takes the broad, fast-looking shield concept and trims it into a shape that tends to suit more riders, while still giving you excellent peripheral coverage and that open, unobstructed view you want on the road, gravel or trail.
The star here is the HiPER Blue Multilayer Mirror lens, which is built to boost contrast and make surface detail easier to pick out in strong light. In real use, that means clearer definition on the road and a more confident read on changing terrain, without giving away the all-day comfort you need from a pair of performance sunnies. The lower air scoops help the lens clear quickly once you’re moving, and the HYDROILO treatment makes sweat, spray and fingerprints easier to wipe away.
For buyers in Australia, the included clear spare lens is a genuine bonus. It makes the S2 much more versatile for dawn bunch rides, late finishes, winter commuting and mixed-weather riding, so you’re not locked into one light condition. Add the TR90 frame, grippy nose and temple contact points, plus the extra alternative-fit nose pad in the box, and you’ve got a premium pair of sunglasses that works well across cycling, running and general outdoor training.
HiPER lens for clearer contrast
Boosts colour separation and surface definition so road texture, trail detail and changing light are easier to read.
Large shield view without the huge look
The S2 keeps the broad field of vision of a performance shield, but in a shape that suits more faces than bulkier oversized options.
Clear spare lens included
Swap to the CAT 0 clear lens for early starts, overcast rides, winter commutes or general eye protection in low light.
Ventilation built into the lens
Lower air scoops help move air across the lens to reduce moisture build-up and help fog clear once you get rolling.
Secure grip when you sweat
Ultra-grip rubber at the nose and tips helps keep the frame settled on rough roads, gravel and hot training days.
TR90 frame comfort
Lightweight, flexible frame material keeps the feel comfortable for long rides without feeling flimsy.
Scratch-resistant interchangeable lenses
The lens system is designed for swapping between conditions while standing up to regular riding use and cleaning.

What's included
Additional notes
HiPER®
This contrast-enhancing lens technology boosts colours, sharpens detail and improves depth perception, so you'll read the road, trail and changing light more clearly.
HYDROILO
This lens treatment helps water, dirt and oil bead off the surface, keeping your vision cleaner in mixed conditions and making the lens easier to wipe down.
TR90
This lightweight, flexible frame material helps keep the glasses comfortable for long rides while staying durable enough for hard daily use.
Great for
Maybe not for
Fit is generally more neutral than very oversized shields, and it has been noted as working especially well for slimmer faces. The frame uses a fixed shape rather than highly adjustable arms or nose pieces, but an alternative-fit nose pad is included. As with most large-lens sunglasses, helmet brow shape can affect clearance, so pairing with your usual road or MTB helmet is worth checking.
vs Oakley Sutro Lite
The Sutro Lite is the obvious rival if you like large-format performance eyewear with contrast-enhancing lenses and strong road style.
vs Smith Wildcat
The Wildcat sits closer to the trail and gravel end of the market, with a similarly versatile shield format and interchangeable lens setup.
vs 100% Speedcraft
If you’re choosing within the same catalogue, the Speedcraft is the more distinctive oversized race option while the S2 trims that concept into an easier everyday fit.
A better choice if oversized shields feel too much
The S2 is the model we’d point you to if you like full-coverage eyewear but find extra-large race glasses too tall or too wide on your face.
The spare clear lens adds real day-to-day value
For Australian riding conditions, a second clear lens makes these much more useful across summer dawn rides, winter commutes and changeable weather.
Fit is secure, but not highly adjustable
These rely more on the frame shape and grippy contact points than on lots of tuning. If you usually need heavy adjustment at the nose or arms, that’s worth keeping in mind.
Ventilation works best once you’re moving
The lens design does a good job of clearing moisture on the move, but like most shield glasses they can still mist briefly if you stop after a hard effort.
