Are expensive youth goggles worth it given how fast kids grow?

It depends on how often your child skis. For occasional ski trips (1–5 days per season), a mid-range youth goggle ($40–$60) with dual lenses, anti-fog coating, and UV400 protection is sufficient. For children in weekly programs or race training, investing in a premium youth goggle ($60–$100) with better anti-fog performance, more durable construction, and superior comfort is worthwhile because the goggle will be worn for many hours and must perform reliably. The cheapest goggles ($15–$25) often lack proper anti-fog coating and may fog so badly that the child refuses to wear them—making them a waste of any money.
