One cold minus three degree morning last year I accidently dropped my backpack out of the tree stand. The propane heater inside barely survived with major damage to the plastic housing and control valve.
The Leupold binocs were now out of focus and had a crack in the housing even though they were armor protected. I suspect the cold added to the damage, possibly causing it with both items.
I finally sent the binocs in and Leupold repaired them no questions asked and no fee. It would have cost me around $200.00 otherwise based on the paperwork they sent back to me.
Lifetime warranty means lifetime with Leupold
