We make sure our optics perform at the highest level by ensuring they will survive extreme temperature changes. Our binoculars are tested under the harshest conditions, so you can use them under the harshest conditions, without fail.
From torrential downpours to crossing rivers, you’ll never have to worry about a Leupold binocular leaking or fogging up. Our proprietary gas blend and seals can withstand extreme temperatures, elevation changes, and shocks, so the internals of the optic stay moisture-free and crystal clear for life.
Built for a lifetime of performance - if at any time the optics on your rangefinding binocular don't perform, we will repair or replace them for free - whether you're the original owner or not.
