Hello everyone,
The RB3025 come in 3 different sizes:
Starting with the 55 being the small size and the 58 considered a medium large; and the 62 large x large
There is another model number for aviators RB8307. These sunglasses are only available in lens size 58mm. The RB3044 is a small size aviator. I personally like the RB3407.
But if you are looking for a classic aviator the way to go is RB3025. By the way the most popular color is the 001 which is the arista with crystal green lens, many would think is black but is green lens :)
