Flat light on a storm day or a bluebird morning in the trees: the 4D MAG XL gives you the widest view Smith makes, in a larger frame that fits over your glasses.

BirdsEye Vision extends the lens into your lower peripheral view, so you catch terrain changes and the riders around you sooner. ChromaPop lenses sharpen contrast so bumps and wind lips show up when the light goes flat. It's the only over-the-glasses goggle in Smith's 4D family, sized for riders who find standard frames too small.

What you'll love on the hill

• BirdsEye Vision opens up the bottom of your view, so you see more of the slope below and beside you.
• Two ChromaPop lenses in the box: one for bright sun and one for low light, so you're set from first chair to last.
• Magnetic MAG lens system makes swaps quick and easy when the weather turns on the chairlift.
• Fits over prescription glasses, so you don't have to switch to contacts to ride.
• 5X anti-fog inner lens and AirEvac venting work with Smith helmets to keep the view clear on hard laps.
• Wide silicone-backed strap and three-layer DriWix foam stay put and wick sweat all day.

Fit note: Medium/Large frame. If you have a lower nose bridge or high cheekbones, a Low Bridge Fit version exists; ask us about it. Comes with a hard case and a microfibre bag with a spare-lens sleeve.
