Pit Viper Ski Helmets & Goggles

Frequently Asked Questions

• How does the Pit Viper Proform Goggle compare to the BN5000 Goggle?

  The Proform Goggle emphasizes a massive field of view using Pit Viper’s Perfect Peripherals design with polycarbonate lenses and CAT 3/CAT 1 VLT options, while the BN5000 uses Worldwide Vision Technology with wrapped side shields, heat-formed foam and custom-molded HDPV lenses for enhanced contrast. Both use Magic Magnets™ for fast lens swaps and Hyperventilator 360 venting, so choice comes down to whether you prioritize the specific lens optics of the BN5000 (HDPV) or the proven wide-peripheral shape and VLT range of the Proform.
• What is Magic Magnets™ and how do lens changes work on Proform and BN5000 models?

  Magic Magnets™ is a magnetic lens retention system that lets you snap lenses in and out quickly and securely without tools, making on-mountain swaps easy between sunny and low-light lenses. Both the Proform and BN5000 include a bonus low-light lens and are designed so lenses seat cleanly against the frame and foam for consistent optics and anti-fog performance.
• Which VLT (visible light transmission) lenses should I choose for sunny, overcast, and flat-light conditions?

  For bright, sunny days choose a low-VLT lens (e.g., the Proform’s CAT 3 ~12%), while overcast or mixed conditions work well with mid-range lenses; for flat light or stormy, low-contrast days use a high-VLT/low-light lens (Proform’s CAT 1 ~44% or the BN5000 bonus low-light). HDPV lenses on the BN5000 also boost contrast in flat light, so carry a sunny and a low-light lens and swap as conditions change.
• Are Pit Viper goggles helmet-compatible and what fit/size should I expect?

  Pit Viper goggles are one-size-fits-most (OSFM) with universal face shaping and a 50mm adjustable strap featuring snakeskin silicone or rubberized touch points to prevent slip, yielding a secure fit with most snow helmets including Pit Viper’s Brainstorm (with MIPS). The heat-formed foam and frame geometry are designed for a seamless seal and comfortable fit across a wide range of head sizes.
• How do Pit Viper goggles manage fogging and ventilation during long days in variable weather?

  Pit Viper uses Hyperventilator 360 full-frame venting plus anti-fog coatings and dual-layer/heat-formed foam to promote airflow and reduce internal moisture buildup, and HDPV lenses resist haze while enhancing contrast. Proper vent alignment with your helmet and keeping vents clear will improve performance, but removing saturated goggles to dry lenses between runs is still recommended in very wet conditions.
