100 Percent Goggles

Frame Tech, Foam and Weather Performance

The foundation of any decent goggle is what sits between your face and the frame. On 100 Percent goggles, that's a triple-layer face foam - a combination of open-cell and moisture-wicking fleece materials that pulls sweat away during hard efforts rather than letting it pool and eventually seep onto the lens. On a long enduro stage or a sweaty bike park lap, that distinction is more important than it sounds.

Ventilation does the heavy lifting against fogging. Forced air intake ports channel moving air across the inner lens surface, which - combined with the factory-applied anti-fog coating - keeps condensation at bay even in the thick, damp air you get riding through Scottish pine forests or Peak District moorland hollows. The coating is the part worth protecting: never wipe the inside of the lens when it's wet, as that's the quickest way to degrade it.

On the lens itself, there's a practical difference between standard Lexan and Ultra HD polycarbonate worth understanding. Lexan is a tough, proven material used across the Racecraft 2, Accuri 2, and Strata 2 - it handles roost and branch strikes well and is optically clear. Ultra HD polycarbonate, found in the Armega, takes impact resistance and optical distortion further. Think of it as the difference between a reliable workhorse and a precision instrument - both do the job, but one does it with noticeably more clarity at speed.

Breaking Down the 100 Percent Goggle Range

Four models, four different riders. Getting the right one comes down to how you ride and what you're willing to spend.

The Armega is the flagship. It uses an Ultra HD shatter-resistant polycarbonate lens with a quick-release system that lets you swap lenses in the car park without tools - genuinely useful when conditions change between runs. Maximum frame coverage, 6-point retention tabs to keep the lens locked under impact, and the widest field of vision in the range. If you're racing downhill or doing serious enduro stages, this is where the money goes. It sits alongside Fox Goggles and Oakley Goggles at the top end of the market - each has its loyalists, but the Armega's lens swap system is a genuine practical advantage.

The Racecraft 2 is the pro-level option with outriggers - small extensions on the frame sides that route the strap and help the goggle sit deeper and more securely inside a full-face helmet. It also features a removable nose guard, which is a useful bit of coverage for riders doing faster, more consequence-laden runs. The outriggers create a better facial seal when you're tucked inside a full-face, reducing the gap where cold air (and roost) can sneak in.

The Accuri 2 is the one most riders end up on. No outriggers, which makes it more adaptable across helmet styles, but it shares the same Lexan lens platform and tear-off profile as the Racecraft 2. That means the same optical quality and the same spares compatibility - a meaningful consideration when you're going through tear-offs on a muddy race day. A solid option if you split time between a full-face and an open-face lid. Smith Optics Goggles occupy a similar versatile space in this bracket, worth a look if you want to compare fit.

The Strata 2 is the entry point. Same lens and tear-off profile as the Accuri 2 and Racecraft 2, trimmed-back frame detailing. If you're new to the sport or buying a second pair for muddy days, it does the job without the premium outlay.

Helmet Pairing and Keeping Them Clean in the UK

Fit between goggles and helmet is one of those things that's easy to overlook until you're on the trail with a gap letting wind whistle across your forehead. Models with outriggers - the Racecraft 2 and Armega - are specifically designed to sit inside the goggle port of a 100 Percent Full Face Helmet or most other modern full-face lids, with the outriggers routing the strap smoothly and pulling the frame flush against your face. The result is a better seal and less movement under impact. For open-face or half-shell use, the Accuri 2 or Strata 2 without outriggers tend to sit more naturally.

Universal curvature across the range means compatibility is broad - 100 Percent goggles are designed to work with most modern MTB helmet profiles, full-face or otherwise. If you're pairing them with a non-100% lid, it's worth checking the goggle port dimensions, but for the vast majority of helmets on the market you won't hit issues.

Cleaning polycarbonate and Lexan lenses correctly is something a lot of riders get wrong. After a muddy run, rinse the lens with clean water before you touch it - wiping dry mud across the surface is how micro-scratches happen, and those compound over time into a lens that hazes your vision. Once rinsed, pat dry with a clean microfibre cloth. For the triple-layer foam, pull the goggle away from the frame if possible and let it air-dry rather than leaving it compressed in a bag. Damp foam that stays damp grows bacteria, breaks down faster, and eventually stops sealing properly against your face - a short drying session after each ride extends the life of the goggle significantly.
