With the BSG4 you're not only choosing for a snow goggle. It's a total package of:
13 years ago, we were riders frustrated with the same problem you know too well: paying a fortune for goggles that fog, scratch or simply don’t keep up. So we asked a rebellious question:
"What if we could build top-tier performance gear without the top-tier price tag?"
That question sparked our first Kickstarter launch and grew into a community of thousands of skiers and snowboarders who trust us every season.
Today, we’re taking everything we’ve learned and pushing it further than ever. A new goggle designed around real frustration, real mountain conditions and real progression.
This is the BSG4.
And it’s built to redefine what “premium” should mean on the mountain.

The BSG4 features an integrated heated lens system that actively prevents fog formation by regulating the lens temperature.
Unlike traditional anti-fog coatings, the heated system works continuously in cold, humid or changing conditions. This ensures clear vision even during intense riding, lifts, or sudden weather changes.
Yes. When the heated lens system is activated, the BSG4 delivers true fog-free performance.
Fog occurs when warm air condenses on a cold lens. By slightly warming the lens surface, the BSG4 eliminates this condensation at the source, instead of trying to reduce it afterward.
The BSG4 battery pack provides up to 12 hours of power, depending on conditions and usage.
This is more than enough for a full day on the mountain. The battery is USB-C rechargeable and can be easily recharged overnight.
No. The battery pack is lightweight and designed to attach directly to the goggle strap.
Once mounted, it stays secure and balanced, without causing pressure or distraction while riding.
If the battery runs out, the BSG4 can still be used as a regular snow goggle.
You simply lose the active heating function, but visibility remains functional thanks to the high-quality lens construction.
ZEISS® SONAR lenses are premium performance lenses engineered to enhance contrast and depth perception in snowy and low-visibility conditions.
They help riders read terrain better, detect changes in snow texture faster and maintain control in flat light or overcast weather.
Yes. The combination of a heated lens system, ZEISS® SONAR lenses and a sealed frame makes the BSG4 suitable for snow, wind, cold, humidity and rapidly changing mountain conditions.
No special maintenance is required. We recommend charging the battery regularly, storing the goggles dry after use, and avoiding unnecessary contact with the inner lens surface, just like with any premium snow goggle.
Yes. Beginners benefit from clear, fog-free vision and ease of use, while advanced riders appreciate the performance, reliability and fast lens changes.
The BSG4 is designed for riders who want confidence in their vision, regardless of skill level.
