Smith Boa Downhill Skiing

Find your size

• Measure the circumference of the largest part of your head
• Wrap a tape measure just above your ears and about 1 inch above your eyebrows
• Use brand sizing charts to find your size
• If you can, try helmets on in-person with your goggles

Fit tips

• A good helmet should feel snug but not tight
• If the helmet rocks back and forth or shifts from side to side, the fit is too loose
• It should sit level on your head no more than 1 inch above your eyebrows

Key features:

• Vents: Let cool air in and warm air out. Adjustable vents help fine-tune airflow
• Liners: Adjust liners or ear pads for warmth
• Goggles compatibility: Fit snugly to the top of the goggles without gaps

Happy riding!

Understand lens shapes

• Cylindrical: More affordable, but can cause more glare and slightly limit peripheral vision
• Spherical: Better peripheral vision, less distortion and less glare. Cost more than cylindrical lenses
• Toric: Offer improved optical clarity and reduced distortion—at a higher price point

Light transmission (VLT)

VLT is the percentage of light that passes through the lens to reach your eyes

• Bright conditions: Look for less than 25%
• Partly cloudy: Aim for between 25%-50%
• Overcast, stormy or low-light: Look for 50% or higher
• Night riding: Use clear goggles or 80%-100%

Other features:

• Low bridge fit: Ideal for those with higher cheekbones or lower nose bridges
• Interchangeable lenses for easy swaps
• Photochromic lenses adjust to changing light
• Extra lens included: Two lenses for different light conditions
