Confused between the two most popular goggles from 509? Understandable. 

But the good thing is, that you don’t really have to worry anymore. I am here with another article that is going to help you finalize one, or both. Let’s see!

Comparing The Aviator And The Sinister

This sounds like the classic comparison of the Aviator and the Wayfarer, doesn’t it? Yeah, it does. It’s not every day we compare two of the best winter sports goggles. Let me brief you that the Aviator and the Sinister are both peas from the cod. That means they are models of 509, a company that has a tremendous reputation in the winter sports goods market. 

Their features are very similar to each other because they’re the twin brothers of the 509 family. But they may lay apart at some time. Let’s compare the 509 Aviator and the 509 Sinister snowmobile goggles with some key points:

Lens Technology

lens technology of 509 Aviator vs Sinister Goggles

The Aviator goggles have a toric lens shape, providing maximum field of vision and optical clarity. They also come with advanced coatings for anti-fogging and anti-scratch properties.

The Sinister goggles offer cylindrical anti-fog lenses designed to provide clear vision in varying weather conditions. Cylindrical lenses give us an unobstructed view when we’re out riding and enjoying our time. 

Lens Change System

Opening up the whole mechanism and inserting the lenses inside the frame in the middle of the field is very tiresome and is not convenient at all when you are trying to enjoy yourself. And if you’re a sportsperson, then it’s definitely not convenient for you to waste your time behind this. 509 has acknowledged this petty little problem of yours and turned in a solution just in time! The magnetic lens change system. Both these goggles come with a fast and easy-to-use magnetic lens change system, allowing users to quickly swap lenses based on weather conditions.

Field of View

Restricted view in the field accounts for many accidents. And you don’t want to be prone to any kind of accident, do you? Worry not, 509 has solved that for you in both of these models.

The Aviator goggles provide an oversized frame for an epic view, offering an expansive field of vision and a wide panoramic view of the surroundings.

The Sinister goggles are designed to offer a wide field of view, providing users with an unobstructed view of their surroundings during snowmobiling.


The ventilation system is the most important thing that a sports goggle needs. It is the basic need of a sports goggle to essentially have a ventilation system to prevent the fogging effect.

The Aviator goggles feature a well-designed ventilation system to prevent fogging and maintain airflow during intense activities.

The Sinister goggles come equipped with advanced frame shuttered venting, which enhances airflow and further reduces the risk of fogging.

Helmet Compatibility

What’s the use of wearing goggles, when they aren’t gonna fit inside your helmet and thus ultimately make you vulnerable to fever and, even worse, accidents! Both the 509 goggles are equally compatible with helmet models and may feature outriggers to improve helmet integration and comfort.

Price Point

Comparing The Aviator And The Sinister

The price of the Aviator is considerably higher than the Sinister model. Aviator is around $200+ which is quite expensive, I’d say. Sinister is a bit lower than Aviator, costing a little more than $160. Though not very cheap, their price is very low than the other high-end exquisite brands. 

But, do note that the models provide excellent value for their performance. While they may have an above-average price compared to some other options, many riders find the investment worthwhile due to the enhanced experience and protection they offer during snowmobiling adventures.


Both the 509 Aviator and the 509 Sinister snowmobile goggles are designed to provide excellent performance, clarity, and comfort for snowmobilers. The choice between the two will depend on individual preferences and specific features that best suit the rider’s needs and preferences. 

So, did you finalize one of them? Or both?
