Have em and love em. Slightly heavier than the proflexes because they have actually ear protection.
Bottoms are a bit lower profile but still nice and flexible. Holes are a bit smaller so no more shell chunks cutting your lips.
Earpieces are rubber and work great. Anchored in two places much like the old hard earpieces but nice and bendy. You can also trim them down if you wish.
Same goggles/lenses as the flexes.
I love mine, I just wish the quality control on thermals lenses was better. They don't last like they used to
