Goggles & Glasses
Used MTB goggles and glasses split into two categories: goggles for DH and enduro, with a full seal, foam interface and strap over the helmet, and glasses for trail and XC, which are lightweight and self-supporting. Goggles such as the Oakley Airbrake, 100% Racecraft and Leatt Velocity pair with full-face helmets and offer the widest field of view, while trail glasses like the Oakley Sutro and 100% Speedcraft protect against debris and UV under an open-face lid. Lens tint matters as much as frame choice.
Goggles or glasses?
Goggles are designed for full-face helmet use — the foam gasket seals against your face and the elastic strap wraps around the helmet, giving maximum coverage against mud, rocks and branches. Use goggles for downhill, enduro racing and bike parks. Glasses work with open-face (half-shell) helmets and sit on your nose and ears like regular sunglasses: lighter, less sweaty and easier to push up on climbs. Most trail and XC riders prefer glasses, gravity riders wear goggles, and the same split runs through the rest of the MTB kit you'd pair with each.
Which lens tint works in UK light?
Lens tint determines what conditions the eyewear works in. Clear lenses suit dark woods and night riding. Rose and vermillion tints enhance contrast in flat light — the best all-round UK choice. Dark smoke or grey lenses cut brightness on sunny days. Photochromic lenses auto-adjust to light conditions (Oakley Prizm Trail, 100% HiPER) and are the most versatile single-lens option but cost more. For goggles, look for easy lens-swap systems such as Oakley Switchlock or the 100% Nose Guard release so you can change lenses trailside.
How do I stop goggles fogging?
Fogging is the biggest problem with MTB eyewear, especially goggles. Dual-pane lenses — two layers with an air gap, like double glazing — resist fogging far better than single-pane. Anti-fog coatings help but degrade with cleaning, so never wipe the inside of a goggle lens with anything abrasive. Vented frames with top and bottom air channels reduce fogging on climbs, and some goggles (Smith Squad, Oakley Airbrake) have better ventilation than others — read reviews specific to UK humid conditions.
Will goggles fit my helmet?
Goggles must fit your helmet. The foam should sit flush against your face with no gaps at the nose or temples, and the goggle-helmet gap — the space between the top of the goggle frame and the helmet visor — should be minimal, since a big gap looks bad and lets in rain and mud. Some helmet brands (Bell, Fox, Troy Lee) design specific goggle-helmet pairings, so goggles, full-face lids and armour and pads are worth thinking about as one setup. For glasses, check they sit comfortably under your helmet brim and don't get pushed down your nose when you look up.
Which brands are worth looking for?
Oakley dominates both categories — the Airbrake MX and Flight Deck for goggles, the Sutro and Jawbreaker for glasses. 100% (Racecraft and Accuri for goggles, Speedcraft and S3 for glasses) offer excellent value and come as standard with many race teams. Leatt and Scott make solid budget goggles, Smith (Squad, I/O) are popular for their ChromaPop lens tech, and Melon Optics offer UK-designed goggles at competitive prices.
What should I check buying used?
Lenses are the critical check — scratches directly affect vision and can't be fixed. Hold lenses up to light and look for surface damage, especially in the centre of the viewing area, and check the anti-fog coating isn't peeling, which appears as a hazy film. On goggles, inspect the face foam: if it's compressed, hardened or peeling, the goggle won't seal properly and will fog constantly. Straps stretch over time, so check the silicone grip strips still hold on the helmet. For glasses, check nose pads and temple tips aren't degraded — these are often replaceable.
