The main difference here is that our bike goggles have a single layer lens whereas our snow goggles have a double layer lens, which stops the lens fogging in cold snowy climates. Without the double lens you're likely to not be able to see all the time as the lens will be prone to fogging.
From a technical standpoint a lot more work and material costs go into creating a good snow goggle lens, which is why the price for snow goggles tends to be higher across the industry than MX / MTB goggles.
