Show Description

These glacier glasses don't make you look like a spread from National Geographic in 1972. Swap out the temples with an integrated leash system, or the classic loop behind the ear style. Dark category 4 lenses will keep your eyes safe at altitude, but are too dark for most day-to-day activities.

  • Tough Grilamid (TR90) frame is known for flexibility, durability and lightness, excellent for performance eyewear frames.
  • Adaptable frame lets you swap out standard temples for ones with an integrated leash, or classic C-temples that loop behind the ear. Leash has a bead for cinching, C-temples keep the glasses anchored to your face.
  • Includes a custom hard case to house temple options and glasses.
  • Removable leather side-shields block glare on snowfields and glaciers.
  • 6-base lens curve.
  • Stainless steel hinge.
  • Lens treatments help keep lenses clear of oil, water, and other smudge-causing gunk.
  • Grey lens with Red Ion or Silver Ion has 5% visible light transmission.
  • Dark Copper lens has 5% visible light transmission.
  • Dark lenses are great for bright locations, but not ideal for everyday tasks like driving.
