Yes, SnugsMoto will protect your ears from wind noise. As they are made from your physical ear impressions, they will protect your ears up to 30db of noise; they will not block outside noise completely (important for health and safety purposes). The level of isolation you get from your SnugsMoto will be dependent on factors including the thickness of skull and depth of ear impression. See Blog on how you need to protect your ears with Snugs.
If you are looking to simply reduce wind noise without added audio capability please look at Snugs Shield Hearing Protection range.
