p> Forgetting your sunglasses on the glacier sucks—snow blindness is serious. So ask your partner (or set your phone) to remind you to pack the Julbo MonteBianco shades ($170, julbousa.com). Broad, curved temples provide maximum coverage, and these can be easily adjusted for a custom fit so the glasses don’t slide around on your face while you’re sliding around on ice and snow. The side shields are removable, but tend to pop out; bring a spare or glue them in place. Available with the photochromic Camel lens (polarized and anti-fog treated) or Spectrum 4 lens (anti-glare).
